Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Tue Sep 28 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. A broad area of low pressure located several hundred miles 
southwest of the Cabo Verde Islands is producing a large area of 
disorganized showers and thunderstorms. Environmental conditions are 
conducive for further development, and a tropical depression is 
likely to form during the next day or two while the system moves 
westward to west-northwestward at 5 to 10 mph over the central 
tropical Atlantic.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

2. A tropical wave located over the far eastern tropical Atlantic 
several hundred miles southeast of the Cabo Verde Islands continues 
to produce a large area of disorganized showers and thunderstorms.  
Upper-level winds are conducive for gradual development, and a 
tropical depression is likely to form in a day or two while the 
disturbance moves westward to west-northwestward at 10 to 15 mph 
over the far eastern tropical Atlantic.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

3. A well-defined low pressure area associated with the remnants 
of Peter is located a few hundred miles east of Bermuda. The shower 
and thunderstorm activity associated with this system has become 
less organized since early Monday.  Although strong upper-level 
winds are likely to prevent significant development, this system 
could still become a short-lived tropical depression later today or 
tonight while it moves northeastward at about 10 mph.  By Wednesday, 
however, conditions are expected to become unfavorable for further 
development.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.
