Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Thu Aug 20 2020

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

The National Hurricane Center is issuing advisories on Tropical 
Depression Thirteen, located several hundred miles east of the 
northern Leeward Islands.

Showers and thunderstorms continue to become better organized in 
association with a tropical wave and accompanying broad area of low 
pressure over the central Caribbean Sea.  Satellite imagery 
suggests that the circulation is becoming better defined and if 
these development trends continue, a tropical depression is likely 
to form today or tonight as the system approaches the northwestern 
Caribbean Sea.  Interests in Honduras and the Yucatan Peninsula 
should closely monitor the progress of this system.  Regardless of 
development, this disturbance will likely produce heavy rains across 
a large portion of Central America and southeastern Mexico late this 
week and this weekend.  An Air Force Reserve reconnaissance aircraft 
is scheduled to investigate the disturbance system later today. 
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

A tropical wave over western Africa is producing disorganized 
showers and thunderstorms near the Africa coast.  This wave is 
expected to move over the far eastern tropical Atlantic on Friday, 
and some slow development is possible through the weekend while it 
moves west-northwestward at 15 to 20 mph across the eastern tropical 
Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...40 percent.
