NWS National Hurricane Center Miami FL
800 AM EDT Tue Sep 23 2025
For the North Atlantic...Caribbean Sea and the Gulf of America:
Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Gabrielle, located over the central subtropical Atlantic.
1. Central and Western Tropical Atlantic (AL93):
Shower and thunderstorm activity associated with a tropical wave
located a little less than 1000 miles east of the Lesser Antilles
continues to show signs of organization. Environmental conditions
are forecast to be favorable for development over the next several
days, and a tropical depression is likely to form by the latter half
of this week while the system moves west-northwestward to
northwestward into the western tropical Atlantic.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...90 percent.
2. East of the Leeward Islands (AL94):
A tropical wave is producing a large area of disorganized showers
and thunderstorms, and gusty winds across much of the Windward and Leeward Islands. This wave is expected to move west-northwestward at 15 to 20 mph, spreading heavy rainfall and gusty winds into Puerto Rico and the Virgin Islands tonight and Wednesday. The system is then expected to slow down and turn northwestward when it reaches the southwestern Atlantic near the Bahamas late this week, and a tropical depression could form when the disturbance is in that region. Interests in the Virgin Islands, Puerto Rico, the Turks and Caicos Islands, and the Bahamas should monitor the progress of this system.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.
