Tropical Storm Cindy For 6/21/2017 2200 CDT

Tropical Storm Cindy is getting closer to land. The latest position from National Hurricane Center is 95 miles or 153 kilometers from Port Arthur, Texas as of 10:00 PM or 2200 CDT. Here is the latest Doppler radar image out of NWS Lake Charles.

It is moving 7 mph or 11 kilometers north-northwest. Cindy could make landfall between 3:00 AM to 5:00 AM or 0300 to 0500 CDT at this rate. The question is where Cindy will make landfall.

The data is from UCAR, to be more specific from ATCF data file. I also included the 5 day cone from National Hurricane Center.Looks to make landfall in East Texas our Southwest Louisiana. Still cannot rule a landfall closer to Houston at this time as tropical cyclones tend to wobble. The area around the center of Cindy has produced heavy rain.

Many areas have seen 1 to 2 inches or 2.54 to 5.08 centimeters of rain per hour. Doppler radar estimates the heaviest rainfall rate is 4 inches or 10.16 centimeters per hour! Some areas could see as much as 5 inch or 12.7 centimeters per hour!

Many areas have seen 3 to 6 inches or 7.62 to 15.24 centimeters of rain based on Doppler radar estimates. The highest is 11 inches or 27.94 centimeters of rain. Again, Doppler radar tends to underestimate rainfall totals. I suspect the highest rainfall total is around 12 to 14 inches or 30.48 to 35.56 centimeters of of rain. I think Houston area could see rain from Cindy, especially later tonight. Rainfall total should be about 1 to 3 inches or 2.54 to 7.62 centimeters with amount as high as 5 inches or 12.7 centimeters of rain. I would not be surprised if thunderstorms form on the west side of Cindy and dumps heavy rain over the Houston area while you sleep.

Once Cindy makes landfall, where does it go? Could it stall out over Texas and dump more heavy rain like Tropical Storm Allison in 2001 did? Or could it just move away from Texas? Here is the next 5 day forecast model.

The cone and heat map has Cindy moving towards Arkansas. No forecast model has Cindy stalling over Texas. It can be possible that Cindy will stall over Texas, but that is unlikely at this point. The forecast models are divided where Cindy will go once inland. It can go to the Midwest and Canada or go all the way to the East Coast. Right now, we should keep an eye on Tropical Storm Cindy as it is getting closer to land.

Tropical Storm Cindy For 6/20/2017 2200 CDT

Potential Tropical Cyclone 3 is now Tropical Storm Cindy. Well, I think, it was Cindy since yesterday. Anyways, let’s cut to the chase. As of 10:00 PM CDT, Cindy is stationary. It has not moved much lately. This complicates forecasting where Cindy will go.

Here is a heat map forecast. It is from ATCF data file. The intensity forecast is also from the same link at UCAR. I also included the 5 day cone from National Hurricane Center.

The heat map is from various ensemble member run within 300 miles (480 kilometers) of a point. From there, a heat map is generated. There is an eastward trend. However, Texas is not out of any landfall risk. The 5 day cone encompass Southeast Texas. The National Hurricane Center states that tropical cyclones are within the cone 67 percent of the time, which means 33 percent of the time they deviate outside the cone. The heat map shows that it can deviate easily from the cone.

In terms of intensity it has increased to 60 mph with central pressure of 997 millibars. The forecast models keep Cindy as a tropical storm. I do not expect a hurricane. The intensity forecast is from

On top of it, Tropical Storm Cindy is a large tropical storm. It has tropical storm force winds extending up to 275 miles! The western half has tropical storm force winds extending up to 140 miles. Tropical storm force winds are 415 miles across! The east side has larger tropical storm force winds.

The main concern is rainfall. The Weather Prediction Center has a seven day total of up to 17 inches around Alabama. Southeast Texas could see to 3 to 7 inches of rain. I would not be surprised if areas see higher totals of 20 inches in some areas. Tropical Storm Cindy is more of a rain event if any. I would be most concerned with heavy rain than wind despite the large area of tropical storm force wind.

Where Cindy goes is anyone’s guess at this point. Forecast models are all over the place. We should know more by tomorrow.

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
1912-1913 1 1
1919-1920 1 1
1926-1927 1 1 1 3
1931-1932 1 1 1 1       4
1958-1959 1 1 1 1 1 1   6
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.

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.

Latest On Typhoon Haima As Of 10:00 PM CST October 19, 2016

Typhoon Haima made landfall as a Category 4 typhoon on Baguio Point in the Cagayan Province with 140 mph winds. The highest wind on land is 119 mph with gusts of 179 mph. The highest measured gust was 124 mph, which is no picnic. One weather station recorded 7 inches of rain in one hour! That would cause a flood for sure. 7 inches of rain in one hour has happened in Southeast Texas during Tropical Storm Allison on June 8-9, 2001. That resulted in 28 inches of rain in 12 hours! As of right now, Haima is a Category 2 typhoon with 110 mph winds. Haima is moving at 14 mph west northwest.

20161019_himawari-8-ahi_geoir_1520z

Where, Typhoon Haima go next after it ravaged the Philippines? Most have Haima making landfall on the Southern China coast. Hong Kong and Macau are also at risk for landfall. That part of China is heavily populated. Everyone China should prepare for Haima as it can be a dangerous storm for them. Interestingly, some models have Haima lopping back towards the Philippines again, like Hurricane Matthew with Florida. That never happened by the way.

20161019_25w_1800z_heatmap

How intense will Haima be by the time it is on China’s door step? Despite being a Category 2 typhoon, Haima is forecast to weaken. It could still maintain its intensity and get stronger. Intensity forecast is not an exact science. One factor is when Haima gets closer to China, it will draw in dry air, which can weaken Haima further. Most forecast have Haima making landfall as a Category 1 typhoon with 92 mph winds. That means most areas will see 50 to 75 mph winds with gusts of 75 to 85 mph.

20161019_25w_intensity_1800z

Haima is going to be more of a rain maker. Many areas could see 8 to 12 inches of rain with isolated totals of 20 inches. Even if Haima makes landfall as a Category 1 typhoon, it should not be taken lightly. Heavy rain and flooding will be the main issue for China.

Latest On Typhoon Haima As Of 10:00 PM CST October 18, 2016

Super Typhoon Haima is now a Category 5 typhoon with 160 mph winds and central pressure of somewhere between 904 to 930 millibars. This is not measured directly. Hurricane force winds extend up to 60 miles, while tropical storm force winds extend up to 210 miles. It has grown as it has intensified. Where it does is very concerning. Haima is moving 16 mph to the west northwest. It looks to affect the Philippines in the next day.

20161019_himawari-8-ahi_colorenhancedir_000z

Looks to be making landfall on the Northern Philippines as a Category 4 super typhoon with 150 mph winds. The size forecast is also worrying. Haima is getting larger. By the time it is over the Philippines, hurricane force winds could extend up to 75 miles with tropical storm force winds extending up to 260 miles. Once it crosses over and weakens, but tropical storm force wind field gets larger.

20161018_25w_1800z_heatmap

Once Haima passes Philippines, it is likely to weaken. The forecast models do not have Haima intensifying into a Category 3 storm once it passes Philippines. I think it has the potential to intensify into a Category 3 typhoon before it makes landfall on China.

20161018_25w_intensity_1800z

Another concerning aspect of Haima is heavy rain. Many areas could see 6 to 12 inches of rain. Mountainous areas could see 20 to 30 inches of rain. This can lead to deadly flooding on top heavy rain that has fallen from Typhoon Sarika. The heavy rain from Haima will make things worse. On top of the heavy rain and flooding, Philipines could likely see sustained winds of 80 to 120 mph winds with gusts of 120 to 180 mph! The highest sustained winds are in a small area and very few will experience it. The gusts is more dangerous as it can knock things over quickly! The Philippines better prepare for Haima. It will get very rough for them.

Latest On Hurricane Matthew As Of 11:00 AM EDT October 8, 2016

Hurricane Matthew made landfall on McClellanville, South Carolina with 75 mph winds and central pressure of 967 millibars. The highest wind on land is 64 mph with gusts of 96 mph. Many areas are seeing 40 to 60 mph winds with gusts of 70 to 90 mph.

20161008_14l_windradii_1100edt

Hurricane force winds extend up to 25 miles, while tropical storm force extend up to 185 miles. Matthew is weakening and could be a tropical storm later today. Intensity forecast have Matthew weakening in the next few days.

20161008_14l_intensity_1200z

Doppler radar out of Wilmington, shows that Matthew is inland. Being close to land has weakened Matthew from a major hurricane.

20161008_kltx_dopplerradar_1114edt

Despite it weakening, Matthew is dumping flooding rain. Flooding will be the major problem for the Southeast, especially for South Carolina and North Carolina. Doppler radar estimate has much as 15 inches of rain near the South Carolina and Georgia border. Areas where South Carolina and North Carolina meet, 6 to 8 inches of rain has fallen so far. More rain is expected to fall in South Carolina and North Carolina.

20161008_kltx_dopplerradar_rainfalltotal_1114edt

20161008_kclx_dopplerradar_rainfalltotal_1123edt

South Carolina could see an additional 4 to 6 inches of rain, which means the total could be 10 to 15 inches of rain. North Carolina could see ab additional 10 inches of rain. North Carolina could see as much as 10 to 15 inches of rain. Some areas could see as much 20 inches of rain.

20161008_14l_72hourrainfalltotal_0504edt

On top of the heavy rain, there is dangerous storm surge. Many areas could see 5 to 7 feet storm surge with isolated areas seeing 10 feet storm surge. Storm surge is more related to size of storm, shallowness of water, and geography. A large Category 1 or 2 hurricane over large area of shallow water with funnel shape area will produce higher storm surge than a small Category 4 or 5 hurricane with deeper waters off the coast. Ike and Sandy produced high storm surge despite being under Category 3 because of their large size and geography of affected areas. Storm surge is the biggest killer in hurricanes. The storm surge will make flooding worse as flood waters cannot drain quickly enough.

20161008_stormsurgefloodingmap_1100edt

Forecast models are all over where Matthew goes. Most have it going eastwards into the Atlantic. Where it goes becomes more complicated. Some have Matthew looping southward towards the Bahamas and even entering the Gulf of Mexico. Some models have it going near Canada. Another fly in the ointment is Tropical Storm Nicole. I do not think it will have much influences due to the small size of the storm.

20161008_14l_1200z_heatmap

Hurricane Matthew is going to be a huge problem for South Carolina and North Carolina. The southern part of Haiti is largely flattened by Matthew. 90 percent of some areas are leveled. The death toll is certainly going to rise. One district, Grand-Anse, at least 470 people have died. I suspect the death toll will be in the thousands. This could be Haiti’s worst hurricane since Hurricane Jeanne in 2004. Jeanne claimed 3,006 people in Haiti. Most of the death was from deadly flooding from heavy rain in the amount of 12 to 15 inches. Most of the death occurred in Gonaïves. Gonaïves had 2,826 of its residence die. Jeanne did not even make landfall as it was a tropical storm.

Latest On Hurricane Matthew As Of 11:00 PM EDT October 7, 2016

Hurricane Matthew has ravaged the Florida coast despite staying offshore and not making landfall. Now, it has its sight on South Carolina. Even though Matthew is a Category 2 hurricane with 105 mph winds and central pressure of 948 millibars. It is still a dangerous hurricane. Not a forced to be reckon with.

20161007_kclx_dopplerradar_rainfalltotal_2251edt

Even though Florida did not get hit by the “dirty” side of the hurricane, it did a number on the state in form of storm surge and flooding. Flooding and storm surge are very dangerous. More people die in them than from high winds. More reason to evacuate. Looking at Doppler radar, looks like South Carolina and North Carolina could be in a rough ride from the “dirty” side of Matthew.

20161008_14l_0000z_heatmap

The heat map forecast of where Hurricane Matthew goes shows a possible landfall on South Carolina and North Carolina. Another possibility, it will stay offshore and still ravage South Carolina and North Carolina, like it did to Florida. This time, they are on the “dirty” side. The “dirty” side have the strongest winds and heaviest rain. Where Matthew goes is anyone’s guess at this point. It may go south and weaken into a tropical storm. Interesting to note another hot spot has it looping southward towards the Bahamas. The forecast intensity has a weakening trend.

20161008_14l_intensity_0000z

Most forecast models have Matthew weakening as it ravages the Carolinas. By tomorrow night, it could be a Category 1 hurricane or strong tropical storm. Regardless, it will be a dangerous event for the Carolinas because of heavy rain and flooding. Doppler radar estimates show 4 to 6 inches of rain has fallen over Savannah and Hilton Head. The heaviest rain looks to be over South Carolina and North Carolina.

20161007_kclx_dopplerradar_rainfalltotal_2311edt

As Matthew gets closer, the winds will get stronger with heavier rains. Georgia, South Carolina, and North Carolina could experience winds of 60 to 90 mph with gusts of 90 to 135 mph. Rainfall totals for South Carolina and North Carolina could be in the neighbor of 10 to 15 inches of rain. Some areas could see as much as 20 inches of rain once it is all over.

20161007_14l_72hourrainfalltotal_1755edt

On top of heavy rain, South Carolina and North Carolina will have to deal with deadly storm surge. Many areas could see 6 to 9 feet storm surge. Some areas could see storm surge as high as 12 feet. The storm surge is mostly a problem in Georgia and South Carolina. The evacuation was the right call. As they say, hide from wind run from water. Storm surge is the reason why people evacuate.

20161007_stormsurgefloodingmap_2300edt

It is going to be a rough Friday night to Saturday for Carolinas. Hopefully everyone who needed to evacuate, evacuated. Storm surge from hurricane is not a force to reckon with.

In Haiti, 877 lives have been lost. The death toll in Haiti is staggering from Hurricane Matthew. The death toll is no doubt going to climb with potential epidemic of water borne diseases like cholera. There have been 17 reported cases of cholera in Haiti, which is the tip of the iceberg. This is could be Haiti’s deadliest disaster since the January 12, 2010 Earthquake, which claimed 316,000 lives.
