Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Wed Sep 29 2021

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

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

1. Satellite images indicate that showers and thunderstorms continue 
to become better organized in association with an area of low 
pressure located several hundred miles south of the Cabo
Verde Islands.  If the current trends continue, advisories will 
likely be initiated on a tropical depression or tropical storm 
later today.  This system is expected to move west-northwestward at 
10 to 15 mph over the eastern Atlantic during the next several 
days.  Additional information on this system, including gale 
warnings, can be found in High Seas Forecasts issued by Meteo 
France. 
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. Showers and thunderstorms remain disorganized in association with a 
a trough of low pressure located several hundred miles southwest of 
the Cabo Verde Islands.  Development of this system appears less 
likely due to the interaction with the larger low pressure area 
located to its east. The system is forecast to drift 
west-northwestward over the tropical central Atlantic during the 
next few days.  
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.

3. An area of low pressure associated with the remnants of Peter  
located several hundred miles south of the coast of Newfoundland 
is producing disorganized showers and thunderstorms. This system 
is moving northeastward into a region of very strong upper-level 
winds, and significant development is not anticipated.  Additional 
information on this system can be found in High Seas Forecasts 
issued by the National Weather Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
