Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Tue Aug 18 2020

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

1. A tropical wave located over the eastern Caribbean Sea is producing 
a large area of cloudiness and disorganized thunderstorms, along 
with strong gusty winds on the north side of the disturbance.  
Significant development of this system is unlikely during the next 
day or so 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 west-northwestward, and a 
tropical depression is likely to form late this week or this 
weekend when the system reaches the northwestern Caribbean Sea.  
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...80 percent.

2. A broad and elongated area of low pressure located about 1000 miles 
west-southwest of the Cabo Verde Islands continues to produce a 
concentrated area of showers and thunderstorms on the west side of 
the disturbance.  Environmental conditions are conducive for further 
development, and a tropical depression is expected to form during 
the next day or two while the system moves generally west- 
northwestward at 15 to 20 mph across the central and western 
portions of the tropical Atlantic.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
