Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 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 newly 
developed Tropical Depression Thirteen, located about 1000 miles 
east-southeast of the northern Leeward Islands.

1. A tropical wave and accompanying broad area of low pressure is 
producing an area of showers and thunderstorms over the central 
Caribbean Sea. This system is gradually becoming better organized, 
and a tropical depression is likely to form in a couple of days 
when the system reaches the northwestern Caribbean Sea.  This 
system is moving westward, and interests in Honduras and the 
Yucatan Peninsula should closely monitor its progress.  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.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

2. A tropical wave over western Africa is producing disorganized 
showers and thunderstorms.  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...10 percent.
* Formation chance through 5 days...medium...40 percent.

Public Advisories on Tropical Depression Thirteen are issued under 
WMO header WTNT33 KNHC and under AWIPS header MIATCPAT3.
