April 2018 Hurricane Season Forecast

Many areas are still reeling from Harvey, Irma, and Maria. Many people lost their properties and are rebuilding. Some lost their life. Hurricane Season is coming as it starts on June 1, 2018.

The analog years I am using are in which previous winter is a weak to moderate La Nina. The forecast is uncertain with El Nino or Neutral.

Based on this, the analog years are 1891, 1945, 1963, 1989, 1996, 2001, 2006, and 2012. They are coming off of a La Nina. Of course, there are other factors in play besides El Nino. I look at Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), Northeast Pacific Warm Pool (NEPWP), Equatorial Indian Ocean (EIO), Tropical South Atlantic (TSAI), Southern Ocean/Roaring Forties, Atlantic Main Development Region (MDR), and Indian Ocean Dipole (IOD). The IOD is based on Australian Bureau of Meteorology forecast.

Analog Years For 2018 (TS/H/MH ACE ACE/Storm)
1891 10/7/1 116 11.6
1945 11/5/2 63 5.7
1963 9/7/2 118 13.1
1989 11/7/2 135 12.3
1996 13/9/6 166 12.8
2001 15/9/4 110 7.3
2006 10/5/2 79 7.9
2012 19/10/2 129 6.8

What affect did those analog seasons have? Let’s start with 1891. Hurricane #1 hit Galveston after intensifying into Category 2 hurricane with 100 mph winds on July 6, 1891. Galveston was flooded from storm surge. It spawned tornadoes in Baton Rouge, which hit a prison, killing 10 people. There is also Hurricane #3 better known as as the Martinique Hurricane was the only major hurricane for the 1891 season. It intensified into a Category 3 hurricane later that day and hit Martinique. There were reports of lightning, which suggests the hurricane was intensifying. Martinique was leveled by strong winds and power waves. Once the hurricane passed, at least 700 people died from the hurricane. Some put the death toll as high as 1,000. The hurricane traverses and makes landfall on Dominican Republic as a Category 2 hurricane. Than it goes northward towards Grand Turk of the Turks and Caicos Islands. The hurricane goes over Bahamas and makes landfall on South Florida as a Category 1 hurricane.

1945 had two major hurricanes hit the US. There is Hurricane #5 or 1945 Texas Hurricane. It made landfall as a Category 3 hurricane over Port Aransas on August 27, 1945. It was a slow moving hurricane as it moved slowly across Texas pelting with strong winds, storm surge, and heavy rain. Some areas saw storm surge as high as 15 feet. The moisture swath could be felt as far as Tampa Bay. The slow movement caused rainfall amounts of 20 inches with amounts likely over 30 inches. The hurricane claimed 3 lives and caused $20 million in damages. Hurricane #9 or 1945 Homestead hurricane is the most intense hurricane to strike Florida since the 1935 Labor Day Hurricane. It was a rather small hurricane. It went over Bahamas and Grand Turk Island as it intensifies. It made landfall on Key Largo as a Category 4 hurricane with 130 mph winds. It emerges out of Florida and makes landfall between Georgia and South Carolina as a tropical storm with 70 mph winds. A total of 26 people died, including 22 in Bahamas and Grand Turk Island. Four died in the US.

1963 was a devastating season. Hurricane Cindy developed in the Gulf of Mexico. It made landfall as a Category 1 hurricane on High Island on September 17, 1963. It stalls over Southeast Texas and dumps heavy rain in amounts of of nearly 24 inches measured. It is certainly possible higher rainfall amounts fell in East Texas. Cindy claimed 3 lives. Hurricane Flora is a large Category 4 hurricane. It was a Cape Verde Hurricane. Once it approached Haiti, Dominican Republic, Jamaica, and Cuba, it stalls out. Flora dumps extremely heavy rain, especially in mountainous areas. In a six day period, some areas see over 100 inches of rain in Cuba, with likely higher amounts. Flora is the wettest known Atlantic tropical cyclone. 8,000 people died from massive flooding from Flora. Flora ranks as one of the deadliest Atlantic hurricanes besides 1780 Hurricane, 1900 Galveston, Mitch (1998), and Fifi (1974).

1989 was an active season. Tropical Storm Allison, which formed from remnant of East Pacific Hurricane Cosme. Allison paid a visit to the Upper Texas Coast on June 27, 1989 with 50 mph wind. Many areas saw 10 to 20 inches with the highest being 30 inches. Eleven people lost their life in Texas Louisiana, and Mississippi. Hurricane Chantal and made landfall on High Island, Texas on August 1, 1989 as a Category 1 hurricane. Chantal produced three feet storm surge at Galveston. An area from Southern Harris County, Fort Bend, and Galveston County saw 8 to 12 inches of rain with amounts as high as 20 inches in Friendswood. Thirteen people die, including 11 offshore. Hurricane Hugo is the most intense hurricane of 1989, which peaked at 160 mph and central pressure of 918 millibars. Hugo first ravages the Caribbean as a monster hurricane. It flattens almost every building in Guadeloupe, Montserrat, St. Croix, and Puerto Rico. Hugo makes landfall as a Category 4 hurricane. Hugo produces monster storm surge in the Charleston area due to its large size. 35 people lost their life in America. Hurricane Jerry is the second hurricane to hit the Upper Texas Coast in 1989. Jerry makes landfall on Jamaica Beach. Galveston sees 75 mph winds with gusts as high as 100 mph. The storm surge destroys a section of State Highway 87. Houston does not feel much impact from Jerry due to it small size. Three people died from Jerry all in Galveston as they were driving on the Galveston Sea Wall.

1996 had many major hurricanes form, more so than 1995. Hurricane Bertha made landfall as a Category 2 hurricane on North Carolina on July 12, 1996. It peaked as a Category 3 hurricane near Puerto Rico. Bertha traversed across the Eastern Seaboard with heavy rain and strong winds. Bertha claimed 12 lives. Hurricane Cesar made landfall as a Category 1 hurricane on Bluefields, Nicaragua on July 27, 1996. It dumped heavy rain over Nicaragua, Costa Rica, and El Salvador. A total of 142 people, which includes 29 missing, mostly in Central America. Cesar crosses into the Pacific and becomes Douglas, which a rare crossover. Douglas is a power Category 4 hurricane. Hurricane Fran formed on August 23, 1996 as a Cape Verde Hurricane. It developed with Hurricane Edouard to the east. Fran becomes a Category 3 hurricane off the Bahamas and is a large hurricane. It made landfall on September 5, 1996 near Cape Fear, North Carolina as a Category 3 hurricane. Fran ravaged the Carolinas with strong winds, storm surge, and heavy rain. It moved northward towards Virginia as it is weakening. Fran becomes more of a rain event as winds are diminishing. Once Fran is gone, a total of 27 lives are lost. Hurricane Hortense formed on September 3, 1996. It was slow to develop and first strikes Guadeloupe as a tropical storm on September 8, 1996. It becomes a hurricane on September 9, 1996. Not too long after Hortense made landfall around Guánica, Puerto Rico as a Category 1 hurricane. It emerges and hits the eastern tip of Dominican Republic. As Hortense moves northward it becomes a Category 4 hurricane and makes its final landfall on West Quoddy, Nova Scotia as a Category 1 hurricane. Hortense dumped flooding rains in Puerto Rico. Hortense claimed a total of 39 lives. Hurricane Lili was a long lived hurricane that formed on October 14, 1996. It ravages Central America, Cuba, Bahamas, and United Kingdom. It made landfall on Matanzas Province, Cuba as a Category 2 hurricane on October 18, 1996. Than heads towards Bahamas where it goes over San Salvador Island and Great Exuma on October 19, 1996. Lili becomes a Category 3 hurricane. Than Lili hits United Kingdom as a strong extratropical storm. Once it is all over, 22 lives, mostly in Central America.

2001 started with Tropical Storm Allison. It made landfall on June 5, 2001 near Freeport, Texas. It lingered over Texas dumped heavy rain. On the early morning of June 7, 2001, heavy rain fell in Beaumon and Sugar Land, Texas. Up to 15 inches of rain fell along feeder band. Louisiana got heavy rain from the large circulation of Allison. Than on the evening of June 8, 2001, thunderstorms form near the center of Allison. Than they all converge over Houston dumping heavy rain for nearly 12 hours. Once it is all over, up to 28 inches fell! A total of 40 inches fell from June 5 to 10 near Beaumont, Texas. Thibodaux, Louisiana got nearly 30 inches of rain. The heavy rain led to severe flooding in Houston area, the worst prior to Harvey. Allison traversed across the Southeastern and Northeastern US dumping heavy rain. Hurricane Gabrielle formed on September 11, 2001, the day America was attacked in New York, Arlington, and Shanksville. It made landfall on September 14, 2001 near Venice, Florida as America was mourning the victims of horrifying terrorist attack. Hurricane Iris was a powerful October hurricane. Iris traveled the Caribbean and rapidly intensified into a Category 4 hurricane with 145 mph winds. On October 8, 2001, Iris makes landfall on Monkey River Town, Toledo, Belize. A 70 mile area is ravaged by strong winds and storm surge. The hurricane claimed 23 lives in Belize and 36 lives including Guatemala, Dominican Republic, and Mexico. Later in the month, Hurricane Michelle forms. Michelle formed near Nicaragua on October 29, 2001 and moved inland near Puerto Cabezas, Nicaragua. It lingered over Nicaragua and Honduras for more than a day dumping heavy rain. 98 people died in Nicaragua and Honduras from deadly flooding, which happened three years to the day Hurricane Mitch ravaged Central America with epic rainfall and flooding. Michelle exits Central America into the Caribbean. It undergoes rapid intensification into a Category 4 hurricane. Michelle makes landfall first on Cayo Largo del Sur, Cuba on November 4, 2001. It moves into Bay of Pigs. Cuba is ravaged by strong winds, waves, storm surge, and heavy rain. Five people died in Cuba from Michelle. Michelle moves northward towards Bahamas on November 5, 2001 and becomes an extratropical storm due to interaction with a cold front.

2006 was predicted to be just as active as 2005. Turned out to be an average season due to a developing El Nino and dry Saharan Desert air blowing over the Atlantic. Tropical Storm Alberto landfall on Florida on June 13, 2006 with 45 mph winds. Many areas in the Southeastern US, Grand Cayman, and Cuba have heavy rain. Two people died in Florida, and one died in North Carolina. Four sailors off the coast of Newfoundland Canada went missing when Alberto is an extratropical storm. Hurricane Ernesto formed west of Grenada on August 24, 2006. It becomes a hurricane southwest of Haiti on August 27, 2006 with 75 mph winds. Ernesto weakens as it interacts with the mountains of Haiti and Dominican Republic. Ernesto makes landfall on Cuba. Ernesto and Florida. Ernesto traverses over Florida be emerging over the Atlantic, which intensifies to 70 mph and possibly a Category 1 hurricane. Ernesto makes landfall on Oak Island, North Carolina on August 31, 2006. Five people died in Haiti, while two died in Virginia when Ernesto is an extratropical storm.

2012 proved to be an active season. Hurricane Isaac was a large Category 1 hurricane that hit New Orleans area and Mississippi. It moved slowly as it dumped heavy rain and produced high storm surge. A large area saw at least 10 inches of rain. The hurricane tested the newly improved levee and flood control system that was ravaged by Katrina in 2005. Hurricane Sandy is the most intense hurricane of the 2012 Atlantic Hurricane season. It is best known as Superstorm Sandy, when it was a very large hurricane/extratropical storm hybrid as it had tropical storm force winds diameter of 1,150 miles! Before it became the superstorm, it hit near Kingston, Jamaica as a Category 2 hurricane on October 24, 2012 and Santiago de Cuba, Cuba as a Category 3 hurricane on October 25, 2012. As it went towards the Atlantic, Sandy got larger as it showed more of an extratropical storm like appearance with a warm core. Than Sandy made landfall as a large extratropical storm with Category 1 winds on Brigantine, New Jersey on October 29, 2012. Sandy set numerous records from lowest air pressure to high storm surge. Battery Park, New York had nearly 14 feet storm surge. Sandy is the most hurricane to make landfall northeast of Cape Hatteras, North Carolina. It also dumped heavy rain mainly over Maryland and Delaware of nearly 13 inches of rain. Sandy claimed a total of 233 lives and did $68.7 billion in damages. Sandy was the second costliest hurricane prior to Harvey and Maria.

Here is a heat map of analog seasons. It is based on 300 mile radius from the storms.

The heat map has Upper Texas Coast, Southeast Georgia, Carolinas, and Windward Islands. However, when you look at the whole basin, everyone is at risk for landfall. I never make landfall predictions. Everyone is at equal risk for landfall.

11 to 16 named storms, likely 13 named storms
4 to 10 hurricanes, likely 7 hurricanes
1 to 4 major hurricanes with 3 major hurricanes
ACE is 80 to 140 with ACE likely of 100 to 125

Many including myself severely underforecasted the 2017 season, which turned out to be active and brutal. The 2013 Atlantic Hurricane Season was overforecasted as it turned out to be a quiet season. There is always room for improvement.

Regardless of forecast, I think 2018 could be an interesting hurricane season. It is the same Atlantic name list used in the 2012 season, which produced Isaac and Sandy. Sandy is retired due to devastating effects on the Eastern Seaboard and Cuba.

What Will Mid January 2018 Be Like?

It has been cold lately. It is a cold start for 2018. There have been cold start to the new year like in 1928 and 1979.

Will there be more cold weather? The Climate Prediction Center 8 to 14 Day Analog could offer some insight.

Some of the analog dates are interesting.
1/19/2001-Cold blasts come on 1/29 with a low of 26°F. The lows would be freezing every night up to 1/23.
1/21/1978-January 1978 is the coldest month on record for Houston. A brief warming occurred on 1/24. It gets cold again on 1/25.
1/29/1952-Heavy rain falls on 2/1. Rainfall totals are Houston WB: 3.22″; Hobby: 3.88″; Galveston: 6.29″. Hobby and Galveston have their wettest 2/1 as of 2018. It is the wettest February day on record for Hobby and Galveston as of 2018.
1/1/1985-A series of cold waves occur in January 1985. Snow falls on 1/2-1/3 and 1/12. A low of 16°F occurred on 1/21.
1/23/1986-A cold blasts went east of Texas. On 1/28, Space Shuttle Challenger launches despite cold weather. The space shuttle explodes in front of horrified audiences and students at school watching the launch.
1/28/1959-Heavy rain falls between 1/29 to 2/4. Rainfall totals are Houston WB: 6.36″; Hobby: 6.93″; Galveston: 2.60″. 3.69″ fell on 2/1 at Houston WB, which is wettest 2/1 as of 2018. It is the wettest February day on record for Houston as of 2018. 2.14″ fell on 1/29 and 0.94″ on 2/2 at Hobby, which is wettest 1/29 and 2/2 as of 2018.
1/11/1961-Snow fell on 1/25. Houston received a trace of snow.

Looking at those analog dates, they mostly had cold blasts. A couple of them had heavy rain. This would suggest we could see another cold blast in mid January. Perhaps we could also see snow or other wintry precipitation. Anything can change.

2017-2018 Winter Forecast

Winter has started and Christmas has passed. It is very cold throughout America. Last winter we had a borderline Neutral/La Nina. This time around, we have La Nina. Other factors to consider are Pacific Decadal Oscillation (PDO), Atlantic Multidecadal Oscillation (AMO), Northeast Pacific Warm Pool (NEPWP), Equatorial Indian Ocean (EIOI), Indian Ocean Dipole (IOD), Tropical South Atlantic (TSAI), Roaring Forties (R40I), Hudson and Baffin Bay (HBB), and Quasi-Biennial Oscillation (QBO). However, since this El Nino is large and strong and has significant impact, it will weigh in more than other factors listed. Here are the analog winters I came up with.

1881-1882
1928-1929
1933-1934
1937-1938
1944-1945
1949-1950
1961-1962
1984-1985
2000-2001

I chose these winters because the previous winter was La Nina or Neutral. Here is a table I created to identify strongest analogs.

Year AMO PDO NEPWP EIOI IOD TSAI R40I HBB QBO Total
1881-1882     1 1 1   1     4
1928-1929 1 1     1     1   4
1933-1934 1 1 1 3
1937-1938 1 1 2
1944-1945 1 1 1 1   1 1 1   7
1949-1950 1 1 1   1 1     1 6
1961-1962 1 1 1     1 1     5
1984-1985       1 1 1 1   1 5
2000-2001 1 1 1 1 1 1 1   1 8

I look at eight ocean and one upper wind patterns based on Fall (September to November) averages. The cutoff for further analysis is four (before 1948 due to QBO data not available). With QBO, the cutoff is five. We can eliminate these winters.
1933-1934
1937-1938

The analogs I will be looking at are:
1881-1882
1928-1929
1944-1945
1949-1950
1961-1962
1984-1985
2000-2001

Let’s start with the ever important temperature. All maps were generated with 20th Century Reanalysis Monthly Composites. They are all Northern Hemisphere.

Alaska, Bering Sea, Southern US, Eastern US, Eastern Canada, Greenland, and Western China are warmer than normal. Arctic, Siberia, Korea, Japan, Central Asia, Southeast Asia, Europe, North Africa, Western US, and Western Canada are cooler than normal. Southeast Texas is warmer. Keep in mind, some areas do not have weather records, so this may be spurious as it includes 1881-1882.

Wonder what winter will be like in the rain department?

It is drier in Western US, Western Canada, Southeast US, Cuba, Bahamas, Southern China, Central Asia, Western Europe, and Northern Europe. It is wetter in Central US, Caribbean, Alaska, Northern Japan, Southeast Asia, and North Africa. Southeast Texas sees average amount of rain in the winter. Again, this may be spurious as it includes 1881-1882.

Let’s look at the upper air pattern.

There is upper level ridging south of Alaska, which is negative East Pacific Oscillation (EPO), Eastern US, Siberia, Greenland, and Northeast Canada. Ridging over Greenland and Northeast Canada is negative North Atlantic Oscillation (NAO). There is troughing over Central Canada and one running from Japan, Korea, and to all of Central Asia. Negative NAO and EPO usually means cold air will go down south.

How were winters like in these analog years?

1881-1882
A warm winter dominated the US. Southeast Texas had a warm winter.

1928-1929
A cold blast came on the start of 1929 in Southeast Texas. Another hard freeze came in February 1929. It did not go above freezing on February 9, 1929 with high of 29°F.

1944-1945
A world engulfed in World War II. No freezes occurred in Southeast Texas.

1949-1950
Most of the US had a warm winter, including Southeast Texas.

1961-1962
Snow fell in Houston area in December 1961. January 1962 had a strong cold blast in America. A strong high pressure with pressure of 1062 millibars was recorded. Many areas saw record lows set. Houston saw a record low on January 10, 1962, which has been beaten in 1977.

1984-1985
Cold blasts occurred in January and February 1985. The 1985 Presidential Inauguration was the coldest on record. Many areas saw record lows set. Houston saw record lows on January 20-21, 1985. Near records occurred on February 1-2, 1985. Snow fell in Houston in January and February 1985. San Antonio saw record snowfall on January 11-13, 1985.

2000-2001
Eastern US had a cooler than normal winter. Southeast Texas had a cold winter.

I am not suggesting we will see a cold blast on par with February 1929, January 1962, January 1985, and February 1985. It is possible this winter could see more cold blasts.

I think this winter could be a cooler winter despite what the past analog winters being warm. I would not be surprised to hear of a major cold blast this coming winter or snow falls again.

April 2017 Hurricane Season Forecast

It is almost this time of year. Hurricane Season is coming as it starts on June 1, 2017. Last year was quite an active hurricane season with Matthew, Nicole and Otto. Tropical Storm Arlene formed in the Northeast Atlantic.

The analog years I am using are in which previous winter is La Nina or Neutral and second year after El Nino. The forecast is uncertain is El Nino will develop later in 2017 despite the water showing warming in the Equatorial Pacific, especially off the coast of South America.

2017
2015-2016 El Nino
2016-2017 La Nina
2017/2017-2018 El Nino/Neutral?

Based on this, the analog years are 1901, 1913, 1972, 1989, 2004, 2006, and 2009. They happened two years after El Nino and came off of a La Nina. Of course, there are other factors in play besides El Nino. I look at Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), Northeast Pacific Warm Pool (NEPWP), Equatorial Indian Ocean (EIO), Tropical South Atlantic (TSAI), Southern Ocean/Roaring Forties, and Atlantic Main Development Region (MDR).

Analog Years For 2017 (TS/H/MH ACE ACE/Storm)
1901 13/6/0 99 7.6
1972 7/3/0 36 5.1
1989 11/7/2 135 12.3
2004 15/9/6 227 15.1
2006 10/5/2 79 7.9
2009 9/3/2 53 5.9

So, what affect did those analog seasons have?
1901
Tropical Storm #2 made landfall on Matagorda, Texas on July 10, 1901 with 50 mph winds. This comes 10 months after the devastating Galveston Hurricane on September 8-9, 1900, which claimed 12,000 lives.

Hurricane #4 is known as the 1901 Louisiana Hurricane. The hurricane formed southwest of Azores on August 2, 1901. It traversed the Atlantic before making landfall on Florida on August 11, 1901. It emerges into the Gulf of Mexico and intensifies into a Category 1 hurricane due to the Loop Current on August 12, 1901. The hurricane makes landfall on Buras, Louisiana as a Category 1 hurricane with 85 mph wind and that makes a second landfall on Ocean Springs, Mississippi on August 15, 1901. Buras reports 4 feet of water, while New Orleans sees the Mississippi River rise by 7 feet. Up to 15 people are known to have died and inflicted $1 million of damages.

1972
1972 was a largely quiet season, but will be most remembered for Hurricane Agnes. It was a hurricane of non-tropical origin that formed over Yucatan Peninsula, Mexico on June 14, 1972. The tropical depression exits Yucatan into the Yucatan Channel. Agnes brushes Western Cuba as it heads towards Gulf of Mexico. Agnes becomes a Category 1 hurricane with 85 mph winds on June 18, 1972 as it is moving northwards towards Florida. Agnes weakens slightly as it makes landfall on Cape San Blas, Florida as a Category 1 hurricane with 75 mph, but likely a tropical storm as there was no sustained hurricane force winds reported. Agnes produced 7 foot storm surge and heavy rain in Florida. There is also a tornado outbreak in Florida from Agnes, which claimed 7 lives. A total of 9 people died in Florida from Agnes. Agnes is responsible for the deadliest tornado outbreak from a tropical cyclone. Agnes continues to weaken as it moves further inland. Agnes goes over the Atlantic on June 22, 1972 as a tropical storm, which developed over North Carolina. Agnes intensifies into a 70 mph tropical storm and makes landfall in Suffolk County east of New York City on June 22, 1972 with 65 mph winds. Once inland, Agnes becomes an extratropical storm. From there, Agnes starts dumping heavy rain throughout a large area of the Northeast from June 23 to 25, 1972. Many areas see 10 to 15 inches of rain including 19 inches of rain in Pennsylvia. Some areas likely saw higher amounts of rain. Pennsylvania took the brunt of Agnes from the heavy rain and massive flooding. Many other states were hit hard from Virginia, Maryland, New York, Ohio, and West Virginia. At least 119 people died in America from flooding, including 50 in Pennsylvania. On top of it, Agnes did $2.1 billion in damages, the most at the time. Agnes was not a major hurricane and will be remembered as an epic flood event in the Northeast, particularly in Pennsylvania.

1989
Before 2001 Tropical Storm Allison, there was 1989 Tropical Storm Allison, which formed from remnant of East Pacific Hurricane Cosme. Cosme made landfall east of Acapulco as a Category 1 hurricane with 85 mph winds. Allison paid a visit to the Upper Texas Coast on June 27, 1989 with 50 mph wind. Many areas in Texas saw 10 to 20 inches of rain. Like 2001 Allison, 1989 Allison loops over Texas, which dumps heavy rain over Northern and Central Louisiana. Many areas saw 15 to 20 inches including 30 inches at Winnfield, Louisiana. Eleven people lost their life in Texas Louisiana, and Mississippi.

Hurricane Chantal is the first hurricane to strike the Upper Texas Coast in 1989. Chantal is a small hurricane that made landfall on High Island, Texas on August 1, 1989 as a Category 1 hurricane with 80 mph winds and central pressure of 984 millibars. The highest winds is 70 mph with gusts as high as 105 mph. Many areas see 50 to 65 mph winds. Chantal produced three feet storm surge at Galveston. An area from Southern Harris County, Fort Bend, and Galveston County saw 8 to 12 inches of rain with amounts as high as 20 inches in Friendswood. One interesting aspect is that the “dirty” side of Chantal was on the southwest side of the hurricane, which produced most of the heavy rain. Thirteen people die, including 11 offshore.

Hurricane Hugo is the most intense hurricane of 1989, which peaked at 160 mph and central pressure of 918 millibars. Hugo was a Cape Verde storm as it formed from a tropical wave that came off of West Africa on September 9, 1989. Hugo became a tropical depression once the tropical wave left Africa. Hugo undergoes rapid intensification over the Atlantic. Hugo first encounter with land as it crosses between Guadeloupe and Montserrat on September 17, 1989 as a Category 4 hurricane with 140 mph winds. Gusts are as high as 210 mph! Guadeloupe is ravaged by strong winds and 8 feet storm surge as many homes are destroyed on top of 10 lives lost. A gust of 184 mph is recorded from a French research ship. Montserrat is ravaged by 20 feet storm surge as almost every house is damaged! Almost everyone are left homeless as a result. 21 people die in Montserrat. Hugo than makes its first landfall on St. Croix. A slowing Hugo puts St. Croix under prolonged hurricane force winds as high wave pelt the island. 90 percent of buildings are leveled and the infrastructure is destroyed by Hugo. The damage is a staggering $1 billion for St. Croix. Later that day, Hugo makes landfall on Vieques and Fajardo, Puerto Rico as a Category 3 hurricane with 120 mph winds. The highest sustained winds are 102 mph with gusts as high as 153 mph. Hugo ravages eastern Puerto Rico and decimates the crops. Hugo goes northward as a Category 2 hurricane. Hugo undergoes intensification to a Category 4 hurricane with 140 mph and central pressure of 944 millibars. Hugo is heading towards America. On the night of September 21, 1989, Hugo makes landfall as a Category 4 hurricane with 140 mph and central pressure of 934 millibars. The highest wind is 119 mph with gusts of 179 mph! Many areas see 80 to 120 mph winds with gusts of 120 to 180 mph. Hugo produces monster storm surge in the Charleston area due to its large size. Twenty feet storm surge are reported as it floods the coastal area. The fast motion of Hugo does not lead to massive flooding. 35 people lost their life in America and costliest hurricane at the time prior to Andrew in 1992.

Hurricane Jerry is the second hurricane to hit the Upper Texas Coast in 1989. It formed in the Bay of Campeche on October 12, 1989. Jerry became a Category 1 hurricane on October 15, 1989. As Jerry approaches the Upper Texas Coast, it continues to intensify. By the time it is getting closer to the Upper Texas Coast on October 16, 1989, it has 85 mph winds. Later that day, Jerry makes landfall on Jamaica Beach. Galveston sees 75 mph winds with gusts as high as 100 mph. The storm surge destroys a section of State Highway 87. Houston does not feel much impact from Jerry due to it small size. Many areas saw 2 to 4 inches with highest amount of over 6 inches in Silsbee. Three people died from Jerry all in Galveston as they were driving on the Galveston Sea Wall.

2004
Hurricane Charley is first of the four hurricanes to ravage Florida in the 2004 season. Charley formed over Barbados on August 9, 2004. Two days later, Charley becomes a hurricane south of Jamaica. As Charley heads towards Cayman, intensifies into a Category 2 hurricane and continues to intensify into Category 3 as it heads closer to Cuba. Charley makes landfall close to Punta Cayamas with 120 mph. The highest winds is 120 mph with gusts of 180 mph over Cuba. Over 13 feet storm is measured in Cuba. Charley continues traverses over Cuba and is west of Havana. Charley emerges from Cuba as a Category 2 hurricane with 110 mph and its first landfall on Florida is Dry Tortuga. A cold front is steering Charley towards Southwest Florida. Forecast models have Charley hitting Tampa Bay as a Category 3 hurricane. As it gets closer to the mainland, Charley undergoes rapid intensification into a Category 4 hurricane with 150 mph winds and 941 millibars. Charley first struck Cayo Costa and than Punta Gorda as a Category 4 hurricane. Charley produce up to 13 feet storm surge in Florida. The highest sustain winds is 128 mph with gusts of 192 mph! The highest measure gust is 172 mph out of Charlotte Regional Medical Center which was before anemometer failed. Charley travels along Interstate 4 and ravages Orlando as a Category 1 hurricane. Many areas see 5 to 8 inches of rain from Charley. Charley emerges into the Atlantic as a Category 1 hurricane. Than it makes landfall Cape Romain and North Myrtle Beach as a Category 1 hurricane. The highest wind is 63 mph with gusts of 96 mph. Charley is the first hurricane to hit South Carolina since Hugo in 1989. Charley dumps 3 to 7 inches of rain and produces 4 to 6 feet storm surge. Once Charley is gone, it claims 15 lives, mostly in Florida. There are 20 indirect deaths, which brings total to 35. Charley also does $16.3 billion in damages.

As Florida is recovering from Hurricane Charley, another storm forms off the Cape Verde Islands, Frances. Frances forms off the Cape Verde on August 24, 2004 and becomes a tropical storm the next day. Frances gains intensity is it traverses over the Atlantic, it undergoes rapid intensification and becomes a hurricane on August 26. Frances intensifies into a Category 4 hurricane with 135 mph winds. Frances undergoes eyewall replacement cycle, causing it to weaken to Category 3 hurricane. AS Frances travels westward and intensifies into a Category 4 with 145 mph winds on September 2, 2004 as it begins to ravage Bahama. Frances weakens into a Category 3 hurricane due to wind shear as it is over Bahamas. Frances maintains Category 2 hurricane with 105 mph as it gets closer to Florida. Frances is a large hurricane with a large eye. To make matters worse, France is moving slowly as it gets closer to Florida. Frances makes landfall on Hutchinson Island, Florida as a Category 2 hurricane with 105 mph winds on September 5, 2004. Frances ravages Florida with strong winds and heavy rain. Many areas in Florida see 10 to 20 inches of rain, which leads to flooding. As Frances is leaving Florida, it emerges into the Gulf of Mexico and make landfall on Aucilla River, Florida as a tropical storm. As Frances weakens, it becomes a huge rainmaker for the Southeast. The Appalachian Mountains draw more moisture out of the storm leading the heavy rain. Many areas in North Carolina see over 20 inches of rain including nearly 24 inches of rain in Mount Mitchell. The flooding causes Asheville to have no water for several days. There are 7 people killed and 43 indirect deaths, which brings the total of 50.

If things got worse, it does, as a tropical wave emerges from Africa on August 31, 2004, which becomes a tropical depression on September 2, 2004. The next day it is Tropical Storm Ivan. Ivan is a tropical storm for two days and on September 5, 2004, it becomes a hurricane and rapidly intensifies into a Category 3 hurricane with 125 mph winds. Ivan first hits Granada as a Category 3 hurricane. Many areas see 80 to 100 mph winds with gusts of 120 to 150 mph. Ivan unleashes devastating winds and destroys numerous buildings including a prison, which allows prisoners to escape causing more trouble. Most of the island is leveled by Ivan as it claims 39 lives. Ivan enters the Caribbean and rapidly intensifies into a Category 5 hurricane with 160 mph. Ivan comes approaches Jamaica on September 11, 2004 and pelts the nation with hurricane force wind and heavy rain. 17,000 people are left homeless from flooding and strong winds of Ivan. Ivan dumped heavy rain on Jamaica as much as 28 inches of rain! It is very likely the amount are higher. 17 people died in Jamaica. As Ivan moves away from Jamaica, it re-intensifies into a Category 5 hurricane. As Ivan comes closer to Grand Cayman, Ivan peaks at 165 mph and central pressure of 910 millibars. Ivan is the tenth most intense hurricane on record in the Atlantic as of 2017. The strong winds of Ivan damage many buildings despite strict building codes. Grand Cayman has winds of 157 mph with gusts as high as 236 mph! Ivan goes between Yucatan Peninsula and Cuba as a Category 5 hurricane. Cuba is being ravaged by full force Category 5 winds and heavy rain. Despite it, there are no reports of casualties in Cuba from Ivan. Ivan enters the Gulf of Mexico as a Category 4 hurricane and maintains it. As Ivan inches closer to the Gulf Coast, people are order to evacuate. The Superdome in New Orleans becomes a “shelter of last resort”, which had been used with Hurricane Georges in 1998. Many evacuate New Orleans as it most of the city is below sea level and would be very vulnerable to storm surge. However, Ivan goes east of New Orleans and makes landfall on Gulf Shore, Alabama as a Category 3 hurricane with 120 mph winds in the small hours of September 16, 2004. Alabama and Florida are hammered by strong winds of 80 to 100 mph with gusts of 120 to 150 mph on top of 15 foot storm surge. Ivan spawned numerous tornadoes, a total of 117, which is the most from a hurricane. On top of it, there is heavy rain of 10 to 15 inches as causes widespread flooding. Ivan moves further inland and weakens into a tropical storm. Appalachian Mountains are getting more heavy rain as it has been flooded by Hurricane Frances several weeks earlier. Part of Ivan break away and moves eastward back into the Atlantic and loops towards Florida. That piece of Ivan enters the Gulf of Mexico and begins to reorganize. By the time it is near Texas/Louisiana, Ivan becomes a tropical depression and tropical storm on September 22, 2004. Ivan makes landfall on Holly Beach, Louisiana as a tropical depression. Some areas in Louisiana and Texas had up to 8 inches of rain. Ivan claimed 92 lives and including 32 indirect deaths, which brings the total to 124 lives.

As Ivan is entering the Gulf of Mexico, a tropical depression develops east of Guadaloupe on September 13, 2004, which made landfall on the island nation. Many areas in Guadaloupe see 8 to 12 inches of rain. The next day it becomes Tropical Storm Jeanne as moves westward towards the Virgin Islands. On September 15, 2004, Jeanne makes landfall on Yabucoa, Puerto Rico as a tropical storm and travels over the island. Many areas see 5 to 10 inches of rain with the highest amount of nearly 24 inches in Vieques. Eight people have died from Jeanne in Puerto Rico. Jeanne exits Puerto Rico and becomes a Category 1 hurricane with 85 mph winds before it makes landfall on the eastern tip of Dominican Republic September 16, 2004. Jeanne traverses on the north side of Hispanola and weakening due to interaction with the mountains. Despite weakening, Jeanne is dumping heavy rain over Haiti and Dominican Republic for 30 hours. The prolonged heavy rain triggers widespread flooding and deadly mudslide in Haiti and Dominican Republic. The highest reported total is 13 inches with totals possibly going as much as 40 inches of rain in the mountains. The coastal city of Gonaives is hardest hit by flooding from Jeanne. At least 2,900 people are known to have died in the city. Throughout Haiti, at least 3,000 people have died from Jeanne. In Dominican Republic, 18 people have died from Jeanne from deadly flooding. Jeanne is now a tropical depression as it exits Hispanola on September 17, 2004. Jeanne lingers east of Bahamas and becomes a Category 1 hurricane with 85 mph winds on September 20, 2004. Jeanne loops around the Atlantic as a hurricane and moves westward towards the Bahamas. Jeanne continues to intensify into a Category 3 hurricane with 115 mph as it hits Abaco Island, Bahamas on September 25, 2004. Jeanne continues westward towards hurricane ravaged Florida. On the night of September 25, 2004, Jeanne makes landfall just two miles away from where Frances made landfall on Hutchinson Island as a Category 3 hurricane with 120 mph winds and 950 millibars, which is the peak of Jeanne. Jeanne produces 6 foot storm surge in Florida. Many areas see 60 to 90 mph winds with gusts of 90 to 135 mph. Many areas see 5 to 8 inches of rain with totals as high as nearly 13 inches of rain. Jeanne weakens as it is over Florida and moves northward dumping heavy rain throughout the Southeast and Mid-Atlantic region. It is unclear how much of the damage is from Charley, Frances or Jeanne. Regardless, Jeanne did a total of $7.66 billion in damages. Jeanne claims over 3,000 lives and exceeds Katrina and Stan in 2005. Jeanne is the deadliest hurricane of the 2000s.

2006
Tropical Storm Alberto formed between Cuba and Yucatan Peninsula, Mexico. The storm peaks at 70 mph west of Tampa Bay on June 12, 2006 over the Loop Current. Alberto makes landfall on Taylor County, Florida on June 13, 2006 with 45 mph winds. Many areas in the Southeastern US see 3 to 7 inches of rain, which leads to flooding. Grand Cayman records up 22.72 inches of rain in 24 hours. Many areas in Cuba see 7 to 12 inches of rain, including 17.52 inches in Pinar del Rio province, Cuba. Two people died in Florida, and one died in North Carolina. Four sailors off the coast of Newfoundland Canada went missing when Alberto is an extratropical storm.

Hurricane Ernesto formed west of Grenada on August 24, 2006. It becomes a hurricane southwest of Haiti on August 27, 2006 with 75 mph winds. Ernesto weakens as it interacts with the mountains of Haiti and Dominican Republic. Ernesto brushes the western tip of Haiti on August 28, 2006 as a weak tropical storm with 45 mph winds. Than Ernesto makes landfall near Guantánamo Bay, Cuba. Ernesto continues northwestward towards Cuba, first hitting Plantation Key, Florida, and than Miami-Dade County as a tropical storm. Ernesto traverses over Florida be emerging over the Atlantic, which intensifies to 70 mph and possibly a Category 1 hurricane. Ernesto makes landfall on Oak Island, North Carolina on August 31, 2006. Haiti sees up to 11 inches of rain and strong winds. Cuba sees rain amounts of 2 to 5 inches of rain with highest of 7.46 inches in Nuevitas, Camagüey. Florida sees 3 to 6 inches of rain with highest of 8.72 inches at South Golden Gate, Florida. The Carolina sees 4 to 8 inches of rain with 14.61 inches being the highest at Wrightsville Beach, North Carolina. Five people died in Haiti, while two died in Virginia when Ernesto is extratropical storm.

2009
Hurricane Bill is the most intense hurricane for 2009 as it was a Category 4 hurricane with 130 mph winds and central pressure of 943 millibars. On August 22-23, 2009, the outerbands of Bill affect the Eastern Seaboard, particularly Massachusetts. Bill dumps heavy rain and produces numerous high waves on the East Coast. Hurricane Bill makes landfall on Point Rosie, Newfoundland as a 70 mph tropical storm. Many areas in Newfoundland and Canadian Maritime provinces experience strong winds and heavy rain. The coastal areas are pelted by high waves that a buoy recorded 87 feet waves!

Hurricane Ida was a Category 2 hurricane with 105 mph winds and central pressure of 975 millibars. However, it is better remembered as a powerful Nor’easter dubbed Nor’Ida. The storm would hammer the East Coast from November 11 to 17, 2009 with heavy rain and strong winds. The highest rainfall total is 18 inches of rain in Virginia. The storm also produce over 7 foot storm surge, which is on par with Hurricane Isabel in 2003.

Some of the analog seasons are inactive like 1972, but are very memorable. It shows it only takes just one to make a huge difference. Some are very active and deadly like 1989 and 2004. There were also Category 5 hurricanes in 1989 and 2004.

Here is a heat map of analog seasons. It is based on 300 mile radius from the storms.

The high risk areas are Cuba, Yucatan Peninsula, Florida Panhandle, South Florda, Carolinas, Bahamas, and Upper Texas Coast. However, when you look at the whole basin, everyone is at risk for landfall, which is why I never make landfall predictions. Everyone is at equal risk as I always say!

The analog seasons are within standard deviation, which indicates this upcoming hurricane season is going to be within average.

What is my prediction for this season?
6 to 12 named storms, likely 10 named storms
3 to 8 hurricanes, likely 6 hurricanes
1 to 3 major hurricanes with 2 major hurricanes
ACE is 65 to 110 with ACE likely of 70 to 100

This excludes Arlene, which formed earlier in April, which would be 11 named storms. I do not think this season will be as active as last year. Of course, it only takes one to be bad like in 1972 with Agnes.

Let’s see how my April 2016 hurricane forecast compare to the actual 2016 season.

7 to 13 named storms, likely 11 named storms
4 to 8 hurricanes, likely 6 hurricanes
2 to 4 major hurricanes with 3 major hurricanes
ACE is 90 to 150 with ACE likely of 100 to 130

2016 Actual Number
15 Named Storms
7 Hurricanes
4 Major Hurricanes
141 ACE

I was off with named storms. I was close with hurricanes, major hurricanes, and ACE. There is always room for improvement either way.

Regardless of forecast, I think 2017 could be an interesting hurricane season. It is the same Atlantic name list used in the devastating 2005 season, which produced Dennis, Emily, Katrina, Rita, and Wilma. Of course some of the names are not there with the exception of Emily.

2016-2017 Winter Forecast

Wow, time flies fast. Every year, time flies faster and it is almost Christmas. Winter is upon us again. Last winter we had a strong El Nino. This time around, we have Neutral conditions, neither La Nina or El Nino. Usually when there is a strong El Nino, La Nina follow. Not this time around. Other factors to consider are Pacific Decadal Oscillation (PDO), Atlantic Multidecadal Oscillation (AMO), Northeast Pacific Warm Pool (NEPWP), Roaring Forties, Equatorial Indian Ocean, and Tropical South Atlantic. However, since this El Nino is large and strong and has significant impact, it will weigh in more than other factors listed. Since, we have a strong El Nino, here are my analog winters. Here are the analog winters I came up with.

1878-1879
1897-1898
1900-1901
1912-1913
1919-1920
1926-1927
1931-1932
1958-1959
1983-1984
2003-2004

I chose these winters because the previous winter was El Nino as they are mostly strong El Nino’s. Those analog had weak La Nina or Neutral. Here is a table I created to identify strongest analogs.

Year ENSO Strong AMO PDO NEPWP EIOI TSAI R40I Total
1878-1879 1 1   1 1   1 5
1897-1898 1 1 1 1       4
1900-1901 1 1 1 3

1983-1984 1   1 1 1 1 1 6
2003-2004   1 1 1 1 1 1 6

I look at seven ocean patterns based on November averages. The cutoff for further analysis is four. We can eliminate these winters.
1900-1901
1912-1913
1919-1920
1926-1927

The analogs I will be looking at are
1878-1879
1897-1898
1931-1932
1958-1959
1983-1984
2003-2004

Let’s start with the ever important temperature. All divisional temperatures and rainfall were plotted with NOAA/NCDC Climate Division data: Mapping and Analysis Web Tool. All maps were generated with 20th Century Reanalysis Monthly Composites.

2016-2017_analog_divisional_temperature_standardizedanomaly-strongest-analog

This is a climate division map of the Lower 48. It does not have 1878-1879. Most of America saw cooler than normal winter, especially in Utah and Colorado. It is also colder in Texas. This would suggest a cooler than normal winter for most of America. The exception is in the Southeast where it is either normal or slightly warmer. What effects does it have around the world?

2016-2017_analog_wintertemperatureanomaly_world-strongest-analog

This one has 1878-1879. Alaska, Kamchatka Peninsula, Southeast Asia, India, Central Asia, and Arctic look to be cooler than normal. The Eastern Tip of Russia, Southeast US, Northeast Canada, North Central Siberia, Sudan, and Chad are warmer than normal. If one is wondering what the winter of 1878-1879 was like, here it is.

djf-1878-1879_wintertemperatureanomaly

It was cooler winter for North America with the exception of Northeast Canada and Greenland. It was also cooler throughout Siberia and Arctic. The NWS New York City has data from 1869 from Central Park. The first one is Normals and Extremes Central Park, NY (1869 to Present) and Average Monthly & Annual Temperatures at Central Park. The winter of 1878-1879 was a cold one with an average of 29.2°F. The average winter temperature in New York City is 35.1°F, which is 6 degrees below normal. The NWS Chicago shows a cooler than normal winter in 1878-1879, but not super cold. The previous winter of 1877-1878 is the warmest on record. It remains the warmest winter to this day. Chicago’s warmest winters occur in El Nino winters. No surprise there as the jet stream goes further south than usual. All Columbus, Ohio Data has the worst winters and 1878-1879 is considered one of the worst winters for Columbus. This would suggest that 1878-1879 was a cold winter for America including Texas.

The reason for 1878-1879 winter to be cold is due to negative North Atlantic Oscillation (NAO) and Arctic Oscillation (AO), which is ridging over Northeast Canada and Greenland. A positive NAO and AO is troughing over Greenland and Northteast Canada.

djf-1878-1879_winter500mbgeopotentialanomalynh

What does the upper level look like in analog winters?

2016-2017winter500mbgeopotentialanomalynh-strongest-analog

There is ridging south of Iceland, South of Bering Sea, and North Central Siberia. There is troughing over Eastern Russia, off the Eastern Seaboard of US, and Western Canada. This would suggest that cold blasts will be from the NAO rather than East Pacific Oscillation (EPO) and West Pacific Oscillation (WPO). It shows that if EPO and WPO are positive, while NAO is negative, there can be cold blasts. Keep in mind, EPO, WPO, and NAO can change quickly.

Wonder what winter will be like in the rain department?

2016-2017_analog_divisional_rain_standardizedanomaly-strongest-analog

From Texas to Maine, it looks to be wetter than normal. Same goes with part of the Midwest and Western US. California looks to be somewhat drier than normal. Again, this does not include 1878-1879, which I have included.

djf-1878-1879_winterprecipitationanomaly_world

Florida, California, Scandinavia, Iceland, Iran, Korea, Japan, and Western Canada were drier than normal in 1878-1879. It was very wet in Texas, Hawaii, Southwestern US, Caribbean, Spain, Portugal, France, Mediterranean region of Europe and Southwest Asia, and India in 1878-1879. Here is a worldwide map with the analogs.

2016-2017_analog_winterprecipitationanomaly_world-strongest-analog

It is the same general areas that are wet and dry. Interestingly, Western Canada is wetter, while Southwest is drier in analog winters. Texas has an average rainfall in analog winters.

How were winters like in these analog years? Were there cold blasts? Cold events are either in America or Texas. Rankings are temperature average since 1895.

1878-1879
Many areas in Northern US experience colder than normal winters.
1878 was a cold year for Europe, especially for United Kingdom.
The previous winter of 1877-1878 was very warm. In fact it is known as the year without winter in 1877.

2003-2004
Northeast US was hit by cold blasts in January 2004. Boston had their coldest January since 1893. Many areas saw over 100 inches of snow, especially in Northern New York.
Snow fell in San Antonio and Austin on Valentine’s Day 2004.

Ranking
America’s 78th coldest winter on record.
Texas’s 88th coldest winter on record.
Upper Texas Coast’s 51st coldest winter on record.

I am not suggesting we will see a cold blast on par with December 1983 or January 2004. It is possible this winter could see a cold blast. Interesting to note that 1958-1959 and 1983-1984 were cold winters for America and Texas.

I think this winter could be a cooler winter. I would not be surprised to hear of a major cold blast this coming winter. It should be an interesting one for sure.

April 2016 Hurricane Season Forecast

20050829_GOES-12_IR_Enhanced_0045Z

Already, Hurricane Alex formed in the Eastern Atlantic in January. It overcame hostile conditions on top of a strong El Nino. What does this mean? It this a harbinger of things to come? Hurricane season is looming as usual as it starts on June 1, 2016.

I chose those years because they are coming off of a strong El Nino on top of a warm Atlantic Multidecadal Oscillation (AMO). Any data before satellite should be taken with a grain of salt. It is likely those seasons are more active than reported.

So, what affect did those analog seasons have?

Hurricane #7 formed south of Haiti as a Category 1 hurricane with 80 mph winds. An American brigantine was wrecked on Tiburon Peninsula with everyone killed. It intensified into a Category 2 hurricane with 105 mph winds as it went over Eastern Bahamas. It intensified into Category 3 on September 30 and Category 4 on October 2, which peaked at 140 mph. The hurricane was a major hurricane at a high latitude up to October 8. It likely became an extratropical storm and affected Europe.

Gale of 1878, which is the eleventh storm of the season. A tropical storm formed west of Jamaica on October 18, 1878. Two days later, it became a hurricane made landfall on Cuba the next day as a Category 2 hurricane with 105 mph winds. It moves northward and makes landfall on Swansboro, North Carolina on the night of October 23, 1878 as a Category 2 hurricane with 100 mph. Hurricane force winds can be felt throughout the Eastern Seaboard. It merged with an extratropical low over New England. Once it was all over, 71 people lost their life from the storm.

1889
Hurricane #4 formed on September 1 east of Barbados. It made landfall on Puerto Rico as an intensifying Category 2 hurricane with 100 mph winds. The hurricane stalls off the Northeast from September 9 to 12 causing flooding from heavy rain and storm surge. The hurricane claims 40 lives.

1897
Hurricane #2 was first spotted in Straits of Florida on September 10. It is probable it formed further east. It makes landfall as a tropical storm around Marquesas Keys, Florida. Once it exits for the Gulf of Mexico, it intensifies into a Category 1 hurricane with 85 mph winds. It makes landfall on Cameron Parish, Louisiana as a hurricane on September 13. It weakens over Texas. The hurricane claims at least 29 lives in Texas.

Hurricane #5 forms south of Windward Islands on October 9. It is probable it formed further east. The hurricane travels over the Caribbean and turns northwest on October 14 towards Cuba. The hurricane makes landfall on Cuba on October 18 as a Category 1 hurricane with 80 mph. Most of the deaths are from the sinking of Triton near Pinar del Rio province. The sinking claims 188 lives and 42 people are rescued. The captain committed suicide. The hurricane weakens to a tropical storm and heads to the northwest and makes landfall around Cape Hatteras, North Carolina with 65 mph winds. The storm produce strong winds and heavy rain throughout the Eastern Seaboard. The storm moves eastward into the Atlantic and becomes extratropical.

1900
Great Galveston Hurricane. It made landfall as a Category 4 hurricane with 145 mph winds. It had a central pressure of 936 millibars. The hurricane produced 15 foot storm surge, which proved deadly. Once it past, 12,000 people died, making it one of the deadliest hurricane in the Atlantic Basin. Only Great Hurricane of 1780 and Mitch are deadlier. It remains the deadliest disaster in American history, exceeding 1906 San Francisco Earthquake and 9/11. Even with the death toll combine of 9,000, the Great Galveston Hurricane claimed way more lives.

1941
Tropical Storm #1 made landfall between Galveston and Port Arthur as a tropical depression after it peaked as a 60 mph tropical storm.

The 1941 Texas Hurricane is Hurricane #2, which comes a week after Tropical Storm #1. The storm lingers over the Gulf of Mexico before intensifying into a Category 3 hurricane with 125 mph winds and central pressure of 942 millibars. The hurricane made landfall late on September 23 as a large 115 mph Category 3 hurricane around Bay City. The hurricane went west of Houston, putting the city on the “dirty” side of the hurricane. Houston received considerable damage from the hurricane. The hurricane claimed 7 lives as it weakened and became extratropical. The extratropical storm would be a problem for Ontario and Quebec, Canada.

Hurricane #4 traverses across the Caribbean. It peaked at 130 mph Category 4 hurricane before making landfall on Cape Gracias a Dios, Honduras on September 27. It went over Central America and hits Belize with 85 mph winds. Once the hurricane exits into Bay of Campeche on September 29 and fizzles. The hurricane claims 43 lives.

The 1941 Florida Hurricane is Hurricane #5, which peaked as a compact Category 3 hurricane with 120 mph winds. It formed north of the Virgin Islands. The hurricane rapidly intensifies before it ravages Bahamas. The hurricane makes landfall as a Category 2 hurricane with 100 mph winds. It is a very small hurricane that dumps light rain. The highest rain is 0.35 inches, which is unusual. The hurricane goes over Gulf of Mexico as a small hurricane before making landfall on Carrabelle, Florida as a Category 1 hurricane with 90 mph winds. The hurricane went over Georgia causing damage. The hurricane claimed at least 10 lives and was not a rainmaker.

Tropical Storm #6 travereses across the Florida Straits before making landfall at Cedar Key. It stalls over and dumps up to 35 inches of rain in four days between October 17 to 22!

1988
Hurricane Gilbert is the most intense hurricane prior to Wilma. It had a central pressure of 888 millibars and 185 mph winds. It is on top of being one of the largest hurricanes known. It directly hit Jamaica as a Category 3 hurricane with 125 mph winds. Jamaica is ravaged by Gilbert from 19 foot storm surge and heavy rains that claim 49 lives. Once it exits Jamaica. Gilbert undergoes explosive intensification over the Caribbean. Than it hits Yucatan Peninsula of Mexico as a Category 5 hurricane with 165 mph winds. It is the first time since Camille hit the Gulf Coast in 1969 as a Category 5 hurricane. The Yucatan Peninsula is ravaged by strong winds, storm surge, and flooding. Once it exits Yucatan Peninsula, Gilbert goes over Gulf of Mexico. There is concerns that Texas could be hit by Gilbert, prompting evacuations.

1998
Hurricane Bonnie formed east of the Lesser Antilles. As Bonnie moved through the Atlantic, it intensified into a Category 3 hurricane with 115 mph winds. Bonnie made landfall as a large 110 mph Category 2 hurricane around Wilmington, North Carolina. Many areas saw 6 to 10 inches of rain from Bonnie. Once Bonnie left, it left 5 people dead and $1 billion in damages.

Tropical Storm Charley forms in the Gulf of Mexico and peaked at 70 mph. Not too long after, Charley made landfall around Port Aransas. On August 24, core rains form around the center of Charley, dumping 17 inches of rain on Del Rio and Ciudad Acuña. 26 people lost their life from Charley, mostly from flooding.

Hurricane Earl formed in the Gulf of Mexico from a tropical wave that left Africa on August 17, 1998. Earl intensified into a Category 2 hurricane with 100 mph winds. It had no discernable eye or eyewall, which is unusual. Earl made landfall around Panama City, Florida as a Category 1 hurricane with 90 mph. As it traversed the Southeastern US, Earl became extratropical. Once it entered the Atlantic, Earl rapidly intensified as an extratropical storm in the Atlantic with central pressure of 957 millibars. Earl made landfall on eastern Newfoundland.

Tropical Storm Frances formed from a monsoonal low in the Caribbean. It slowly moved into the Gulf of Mexico. The large area of thunderstroms became a tropical depression east of Brownsville, Texas. The lack of sheer and warm water, allowed Frances to strengthen into a large tropical storm as it made landfall around Corpus Christi, Texas as a strong tropical storm. Frances dumped heavy rain over Texas and Louisiana. Many areas saw 10 to 20 inches of rain. 44 inches of rain was reported in Escuintla, Chiapas, Mexico. Frances produced 8 foot storm surge, which is high for a tropical storm. It is due to its very large size.

Hurricane Georges is a long lived and very intense hurricane. A classic Cape Verde storm, which formed from a tropical wave. Georges rapidly intensified into a large Category 4 hurricane with 155 mph winds as it travesed the Atlantic heading towards Lesser Antilles. It weakened to Category 3 with 115 mph winds as it first made landfall on Antigua. It weakens to a Category 2 before it intensifies to a Category 3 with 115 mph winds before making landfall around Faljardo, Puerto Rico on September 21. It dumps extremely heavy rain over Puerto Rico of up to 30 inches. It exits Puerto Rico and heads for Dominican Republic and Haiti and makes landfall on September 22 as a 120 mph Category 3 hurricane. The mountainous terrain weakens Georges, while dumping extremely heavy rain of 39 inches over Dominican Republic and Haiti. Once Georges left, 589 people die in Hispanola, mostly from flooding. Than Georges heads to Guantanamo Bay, Cuba on September 23. Georges traverses over Cuba dumping heavy rain of up to 24 inches. Georges claims 6 lives in Cuba before heading towards Straits of Florida as an intensifying Category 2 hurricane with 110 mph winds. Georges made landfall on Key West with 105 mph winds on September 25. Georges heads to the Gulf of Mexico and makes final landfall on Biloxi, Mississippi as a 105 mph Category 2 hurricane on September 28. Georges stalls and moves slowly east dumping heavy rain of over 38 inches of rain! The Louisiana Superdome is used as a “shelter of last resort”, a first. The Superdome would be used for Ivan in 2004 and lastly with Katrina in 2005 which proved disasterous. Georges long reign of terror claimed 604 lives.

Hurricane Mitch is the most intense since Gilbert in 1988. Mtich formd from a tropical wave that intensified over the Caribbean. It underwent explosive intenisfication On October 25-26. Mitch had a central pressure of 905 millibars and 180 mph winds over the Western Caribbean. Mitch goes over Swan Island during its peak and a schooner, Fantome, gets destroyed, claiming 31 lives on October 27. Guanaja Island is hammered with 120 mph winds for two days, destroying every vegetation on the island. Mitch was forecasted to go north towards Yucatan Peninsula, but went southwards due to upper level ridging. Mitch makes landfall as a 80 mph Category 1 hurricane east of La Ceiba, Honduras on October 29. It lingers over Central America as it dumps extremely heavy rain as it draws moisture from Pacific and Caribbean due to its large circulation. The heavy rain causes deadly mudslides and massive flooding. Some areas record up to 75 inches of rain in the mountains. Very likely that some areas see over 100 inches of rain during its reign. Some rain gauges recorded 25 inches of rain in 6 hours before it got washed away! Mitch moves slowly over Central America dumping heavy rain nonstop, mainly at night. The heavy rain causes massive and deadly mudslides in the mountainous regions. Many areas are flooded greatly. Mitch than goes over the Gulf of Mexico and intensifies into a 60 mph tropical storm before making landfall near Naples, Florida. Many areas see 6 to 10 inches of rain as it spawns 5 tornadoes. Mitch becomes an extratropical storm as it heads to the Atlantic. What was Mitch ravages Ireland and United Kingdom with heavy rain, strong winds, and high waves. Once Mitch is gone for good, at least 19,325 people have died from deadly floods and mudslides. Hurricane Mitch is the deadliest hurricane since the Great Hurricane of 1780, which claimed 28,000 lives! Mitch is one of the deadliest disaster in the Western Hemisphere besides 2010 Haitian Earthquake and Great Hurricane of 1780.

Interesting those analog seasons have two of the deadliest hurricanes, Great Galveston Hurricane and Mitch. Does this mean that 2016 will be a deadly year? No, but anything is possible. Also, interesting to note, many hurricanes made landfall on the East Coast like in 1878 and 1998.

Here is a heat map of analog seasons. It is based on 300 mile radiusm from the storms.

2016AprilAnalogHurricaneMap

Looking at the heat map, the highest risk areas are Central and Eastern Gulf of Mexico, Southwest Caribbean, Hispanola, Lesser Antilles, and Eastern Atlantic. However, when you look at the whole basin, everyone is at risk for landfall, which is why I never make landfall predictions. Everyone is at equal risk!

It only takes one to be a bad year, no matter how inactive the season is. Case in point, 1983, a very quiet season. It is best known as Hurricane Alicia ravaging Southeast Texas on Augus 18, 1983. Let’s go to analog statistics.

The analog seasons are within standard deviation, which indicates this upcoming hurricane season is going to be within averages.

What is my prediction for this season?
7 to 13 named storms, likely 11 named storms
4 to 8 hurricanes, likely 6 hurricanes
2 to 4 major hurricanes with 3 major hurricanes
ACE is 90 to 150 with ACE likely of 100 to 130

This includes Hurricane Alex that formed in January. Excluding Alex, it would be 10 named storms, 5 hurricanes, and 3 major hurricanes. Some of the analog seasons had high ACE/storm, like 1878, 1958, and 1998. Interesting to note they all have 8 at the end.

Let’s see how my April 2015 hurricane forecast compare to the actual 2015 season.

6 to 10 named storms, likely 8 named storms
4 to 6 hurricanes, likely 4 hurricanes
1 to 3 major hurricanes with 2 major hurricanes
ACE is 40 to 90 with ACE likely of 50 to 80

2015 Actual Number
11 Named Storms
4 Hurricanes
2 Major Hurricanes
63 ACE

I was off with named storms. I got it right with hurricanes and major hurricanes. I was withing range for ACE.

Regardless, I think 2016 will be an interesting season. So fasten your seatbelt and prepare for a bumpy ride.

2016 And 2017 Atlantic Hurricane Season Forecast

Christmas is sure looming, but the 2016 Atlantic Hurricane Season is not too far away, six months from now. I am going to also look at 2017 Hurricane Season, which would be second year following the strong El Nino of 2015-2016. That is eighteen months from now at the writing of this article.

Analog Years For 2016 (TS/H/MH ACE ACE/Storm)
1878 12/10/2 181 15.1
1889 9/6/0 104 11.6

I came up with the analog for 2016, since we are in El Nino and once El Nino fades, La Nina comes and it can get strong. It is based on past El Nino and warm Atlantic Multidecadal Oscillation (AMO). Here is the statistics for 2016 Analog Season.

Standard Deviation
3.28

Looking at it, it is above average ranging from number of storms and hurricanes. Major hurricanes is about the same. However, keep in mind, anything before satellite should taken with a grain of salt. Seasons prior to satellite would of likely had more storms than recorded, but they could be in the middle of the Atlantic or some short lived tropical storm. Seasons like 1889 and 1897 likely had major hurricanes.

So, what is my prediction for the 2016 Atlantic Hurricane Season
10 to 16 named storms, likely 14 named storms
6 to 10 hurricanes, likely 8 hurricanes
2 to 5 major hurricanes with 3 major hurricanes
ACE is 110 to 190 with ACE likely of 130 to 160

Looks to be an active 2016 Atlantic Hurricane Season.

Here is a GIS heat map I created for 2016 analog seasons. It is within 300 miles.

2016DecemberAnalogHurricaneHeatMap

Looking at the heat map, there are areas most at risk. Off the Eastern Seaboard with North Carolina most at risk. Haiti and Dominican Republic, Caribbean and Cuba, Southwest Florida, and Gulf of Mexico. Anywhere is at risk, but those areas especially are the ones to keep an eye on. Let’s see what 2017 Atlantic Hurricane Season forecast.

Analog Years For 2017 (TS/H/MH ACE ACE/Storm)
1879 8/6/2 64 8.0
1890 4/2/1 33 8.3
1898 11/5/1 113 10.3
1943 10/5/2 94 9.4
1959 11/7/2 77 7.0
1999 12/8/5 177 14.8

I came up with the analog for 2017, based on the second year following El Nino. Warm AMO is taken into account. Here is the statistics for 2017 Analog Season.

2017
Mean
9.33/5.50/2.17
10/6/2 (Round Up)

ACE/Storm
Mean

Looking at it, 2017 is closer to average than 2016. Interestingly, there are more major hurricanes on average than compared to 2016 analog seasons. Still, looking at the actual analog seasons, it is generally less active. Again, keep in mind, anything before satellite should be taken with a grain of salt. There were likely more storms before satellite era that went undetected.

So, what is my prediction for the 2017 Atlantic Hurricane Season
9 to 14 named storms, likely 12 named storms
4 to 9 hurricanes, likely 7 hurricanes
2 to 4 major hurricanes with 3 major hurricanes
ACE is 100 to 180 with ACE likely of 120 to 150

Here is a GIS heat map I created for 2017 analog seasons. It is within 300 miles.

2017DecemberAnalogHurricaneHeatMap

Looking at the hot spots, West Indies, Lesser Antilles, Caribbean and Cuba, Off the Eastern Seaboard, Bahamas, and Western Gulf of Mexico with Texas and Louisiana at most risk. Again, anywhere is at risk, but those areas especially are the ones to keep an eye on.

The 2016 and 2017 Atlantic Hurricane Forecast is all preliminary at this time. It is subject to change. I should have a better idea about the 2016 Atlantic Hurricane Season in April 2016 and for 2017, April 2017. That would be sixteen months from now of course. This is just a thought because of the strong El Nino we have and what impact a strong El Nino has on the Atlantic. By Summer 2016, it could be still El Nino. It could also be Neutral or La Nina by than. Until than, please check back in April 2016 for the 2016 Atlantic Hurricane Season forecast.
