Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Thu Sep 23 2021

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

The National Hurricane Center is issuing advisories on Tropical
Depression Eighteen, located about 1800 miles east-southeast of the
northern Leeward Islands.

The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Rose, located more than 1300 miles
west-northwest of the Cabo Verde Islands.

A gale-force, non-tropical low pressure system, the remnants of
Odette, is located a little more than 600 miles west-northwest of
the westernmost Azores.  While showers and thunderstorms remain
limited near the low, only a small increase in this activity could
result in the formation of a subtropical or tropical cyclone while
it moves generally southward over marginally warmer waters during
the next day or two.  Strong upper-level winds are expected to
develop over the system by this weekend, which should then limit
further development.  Additional information on this system,
including gale warnings, can be found in High Seas Forecasts issued
by the National Weather Service.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

Another tropical wave is expected to move off the west coast of
Africa by the end of the weekend. Thereafter, environmental
conditions are forecast to be conducive for gradual development of
this system as it moves westward at 10 to 15 mph over the far east
Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
