Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM 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 Lesser Antilles.

Satellite-derived wind data indicate an elongated area of low 
pressure associated with the remnants of Peter is located a few 
hundred miles southeast of Bermuda.  Showers and thunderstorms have 
become a little better organized since last night, and environmental 
conditions are marginally conducive for some further development of 
this system.  Peter could briefly become a tropical depression again 
during the next day or two while it moves northeastward at about 10 
mph.  By midweek, environmental 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.

Disorganized showers and thunderstorms are associated with a broad 
area of low pressure located several hundred miles southwest of the 
Cabo Verde Islands.  Environmental conditions are forecast to be 
conducive for further development of this disturbance, and a 
tropical depression is likely to form around midweek while it moves 
westward to west-northwestward at 5 to 10 mph over the central 
tropical Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...80 percent.

A tropical wave is expected to move off of the west coast of Africa 
later today.  Upper-level winds are forecast to be conducive for 
gradual development thereafter, and a tropical depression is likely 
to form in a few days while the system moves westward to 
west-northwestward at 10 to 15 mph over the far eastern tropical 
Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...80 percent.
