Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sat Aug 7 2021

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

1. Showers and thunderstorms associated with a broad area of low 
pressure located about a hundred miles southwest of the 
southwesternmost Cabo Verde Islands have been decreasing during the 
past several hours.  Strong upper-level winds and cooler waters are 
expected to prevent significant development of this system while it 
moves toward the west or west-northwest at about 10 mph during the 
next few days.  Regardless of development, locally heavy rainfall 
and gusty winds still are possible over portions of the westernmost 
Cabo Verde Islands through Sunday.
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 5 days...low...20 percent.

2. A small but well-defined area of low pressure located over the 
tropical Atlantic about a thousand miles west of the Cabo Verde 
Islands continues to produce limited shower activity.  
Environmental conditions are expected to become a little more 
favorable for gradual development over the next several days, and 
this system could become a tropical depression by the middle of next 
week.  The system is forecast to drift toward the west-southwest or 
west during the next couple of days, and then move a little faster 
toward the west-northwest by mid-week. 
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 5 days...medium...40 percent.

3. A surface trough of low pressure is producing disorganized showers 
and thunderstorms over the central tropical Atlantic several 
hundred miles east of the Windward Islands.  Some gradual 
development of this system is possible while it moves 
west-northwestward at 10 to 15 mph, reaching portions of the Lesser 
Antilles late Monday and then moving across the eastern Caribbean 
Sea and Greater Antilles through the middle of next week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
