8/8 Tropical Weather Update

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sun Aug 8 2021

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

1. An elongated area of low pressure located several hundred miles 
east of the Windward Islands continues to produce disorganized 
showers and thunderstorms.  Environmental conditions are expected 
to be favorable to support some gradual development over the next 
few days, and this system could become a tropical depression while 
it moves west-northwestward at 10 to 15 mph.  The disturbance is 
forecast to reach portions of the Lesser Antilles late Monday, and 
then move near the Virgin Islands and Puerto Rico on Tuesday, and 
near Hispaniola around the middle of this week.  Interests in those 
areas should monitor the progress of this system, as it could bring 
locally heavy rainfall and gusty winds to portions of that area.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.

2. Showers and thunderstorms associated with an area of low pressure 
located over the tropical Atlantic about midway between the Cabo 
Verde Islands and the Lesser Antilles have diminished this morning. 
Although environmental conditions appear to be only marginally  
conducive for development, this system could still become a 
tropical depression later this week while it moves toward the 
west-southwest or west at around 10 mph.
* Formation chance through 48 hours...low...30 percent. 
* Formation chance through 5 days...medium...40 percent.
