Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Thu Sep 4 2025

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

1. Tropical Atlantic (AL91):
A broad area of low pressure, associated with a tropical wave, is 
producing a concentrated but still disorganized area of showers and 
thunderstorms over the eastern tropical Atlantic.   Environmental 
conditions are favorable for development of this system, and a 
tropical depression is likely to form by this weekend as it moves 
slowly westward at 5 to 10 mph across the central tropical Atlantic. 
This system is likely to be near the Lesser Antilles by the middle 
to latter part of next week, and interests there should continue to 
monitor its progress.
* Formation chance through 48 hours...medium...60 percent. 
* Formation chance through 7 days...high...90 percent.
