Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Fri Aug 22 2025

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

Active Systems:
The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Erin, located over the northwestern Atlantic
Ocean.

Southwestern Atlantic (AL90):
Showers and thunderstorms have not become any better organized this
evening in association with a trough of low pressure located a
couple hundred miles northeast of the northern Leeward Islands.
Environmental conditions appear conducive for further development of
this system, and a tropical storm is very likely to form this
weekend while it moves northwestward and then northward over the
southwestern Atlantic.  Interests in Bermuda should monitor the
progress of this system as watches or warnings could be required on
Saturday.  For additional information, including gale warnings,
please see High Seas Forecasts issued by the National Weather
Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.

Central Tropical Atlantic (AL99):
Showers and thunderstorms associated with a tropical wave located
about midway between Africa and the Windward Islands remain
disorganized.  While there is still some chance that a short-lived
tropical depression could form during the next day or so, the system
is expected to move through a less conducive environment on
Saturday.  The wave could reach a slightly more favorable
environment late this weekend into early next week as it approaches
the Windward Islands.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...30 percent.
