Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Tue Jul 28 2020

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

1. Shower activity associated with a low pressure area located about 
750 miles east of the Windward Islands is gradually increasing 
in organization.  However, recent satellite-derived wind data 
indicate that the circulation remains broad and elongated, and the 
low does not yet have a well-defined center of circulation.  
Environmental conditions are expected to become somewhat more 
conducive for development, and a tropical depression or tropical 
storm is likely to form during the next couple of days while the 
system moves west-northwestward at 15 to 20 mph and approaches the 
Leeward Islands.  Regardless of development, locally heavy rains and 
gusty winds are likely across portions of the Leeward Islands on 
Wednesday and will spread westward to the Virgin Islands and Puerto 
Rico Wednesday night and Thursday.  Interests on these islands 
should continue to monitor the progress of this system, and 
tropical storm watches or warnings could be required for portions 
of the area later today.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.
