Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Mon Sep 27 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 well-defined low pressure system associated with the remnants of 
Peter is located a few hundred miles east of Bermuda. Although 
shower and thunderstorm activity is currently disorganized, 
environmental conditions are expected to remain marginally 
conducive for a short-lived tropical depression to form tonight or 
Tuesday while the system moves northeastward at about 10 mph.  By 
Wednesday, however, conditions are expected to become unfavorable 
for further development.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

2. 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.

3. A tropical wave located just offshore the west coast of Africa 
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 couple 
of days 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.
