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.

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.

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.

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.
