NWS National Hurricane Center Miami FL
800 AM EDT Tue Aug 18 2020

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

1. A tropical wave over the eastern Caribbean Sea is producing an area 
of disorganized thunderstorms and gusty winds.  Significant 
development of this system is unlikely during the next couple of 
days while it moves quickly westward at about 20 mph across the 
eastern and central Caribbean Sea.  After that time, however, the 
wave is forecast to move more slowly westward, and a tropical 
depression could form late this week or this weekend when it reaches 
the northwestern Caribbean Sea.  
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.

2. A broad area of low pressure located about 900 miles 
west-southwest of the Cabo Verde Islands is producing a 
concentrated area of showers and thunderstorms.  Environmental 
conditions are conducive for further development, and a tropical 
depression is likely to form within the next couple of days while 
the system moves westward to west-northwestward at 15 to 20 mph 
across the central and western portions of the tropical Atlantic.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
