Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Wed Sep 17 2025
For the North Atlantic…Caribbean Sea and the Gulf of America:
Central Tropical Atlantic (AL92):
Satellite wind data indicate that the low pressure system located
about midway between the Windward Islands and the Cabo Verde Islands
is gradually becoming better defined. In addition, the associated
shower and thunderstorm activity has become a little more
concentrated during the past several hours. If these trends
continue, advisories could be initiated on a tropical depression
later today. The system is expected to move generally northwestward
at 10 to 15 mph over the central tropical and subtropical Atlantic
during the next several days. 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…high…90 percent.
* Formation chance through 7 days…high…90 percent.
Eastern Tropical Atlantic:
A tropical wave located a couple of hundred miles east-southeast of
the Cabo Verde Islands is producing an area of disorganized showers
and thunderstorms. Environmental conditions are only marginally
conducive, and any development of this system should be slow to
occur while it moves westward at 15 to 20 mph across the eastern and
central portion of the tropical Atlantic. Regardless of
development, this system will likely bring areas of heavy rain
across the Cabo Verde Islands later today and Thursday.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 7 days…low…20 percent.
