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.
