Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Thu May 20 2021

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. A non-tropical low pressure area located about 625 miles east- 
northeast of Bermuda is forecast to strengthen into a storm-force 
low pressure system tonight.  On Friday, the low is expected to turn 
west-southwestward over warmer waters and will likely become a 
subtropical cyclone near and to the northeast of Bermuda.  After 
that time, the low is forecast to move northward and northeastward 
into a more hostile environment by Saturday night or Sunday.  
Additional information on this developing low pressure area can be 
found in High Seas forecasts issued by the NOAA Ocean Prediction 
Center and forecast products, including a tropical storm watch, 
issued by the Bermuda Weather Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...80 percent.

2. A disorganized area of cloudiness and thunderstorms over the 
western Gulf of Mexico is associated with a surface trough of low
pressure. Conditions are expected to be marginally conducive for
some development over the next day or so before the disturbance 
moves inland over the northwestern Gulf coast late Friday or Friday 
night. Regardless of development, the system could produce heavy 
rainfall over portions of southeastern Texas and southwestern 
Louisiana on Friday and through the weekend.  Additional information 
on the rainfall and flooding potential can be found in products 
issued by your local National Weather Service Forecast Office. 
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.
