Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sat Sep 12 2020

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

The National Hurricane Center is issuing advisories on Tropical
Storm Paulette and Tropical Depression Rene, both located over the
central Atlantic Ocean, on Tropical Storm Sally, centered over
the southeastern Gulf of Mexico, and on newly formed Tropical
Depression Twenty, located over the eastern Tropical Atlantic.

A surface trough over the north-central Gulf of Mexico is producing
limited shower activity.  While some slow development of this system
is possible, strong upper-level winds related to Tropical Storm
Sally will probably limit the chances of tropical cyclone formation.
The disturbance is forecast to move westward and then southwestward
over the northern and western Gulf of Mexico through the next few
days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

Showers and thunderstorms located near and west of the Cabo Verde
Islands are associated with a broad area of low pressure.
Environmental conditions support some additional development, and a
tropical depression could form over the far eastern tropical
Atlantic during the next two or three days while the system moves
slowly west-northwestward. By mid-week, upper-level winds should
become less conducive for development.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...60 percent.

WMO header WTNT35 KNHC and under AWIPS header MIATCPAT5.
Forecast/Advisories on Tropical Depression Twenty are issued under
