Tropical Weather Update – Potential Tropical Cyclone Nine
Friday, September 26, 2025 – 5:00 PM EDT
The National Hurricane Center has begun issuing advisories on Potential Tropical Cyclone Nine, which is expected to strengthen into a tropical storm this weekend. Watches and warnings are already in effect for parts of the Bahamas as the system organizes.
As of 5 PM EDT, the disturbance was located near latitude 20.9°N, longitude 74.6°W, about 55 miles north-northwest of the eastern tip of Cuba and 200 miles south-southeast of the central Bahamas. The system is moving northwest at 9 mph with maximum sustained winds of 35 mph. Minimum central pressure is 1008 mb.
Watches and Warnings
Tropical Storm Warning: Central Bahamas, including Cat Island, the Exumas, Long Island, Rum Cay, and San Salvador.
Tropical Storm Watch: Northwestern Bahamas, including Eleuthera, New Providence, the Abacos, Berry Islands, and Grand Bahama Island.
A Tropical Storm Warning means tropical storm conditions are expected in the warning area within 36 hours. A Tropical Storm Watch means conditions are possible within 48 hours.
Forecast and Track
The system is expected to gradually strengthen, becoming a tropical depression on Saturday and a tropical storm by Saturday night or early Sunday. On its current forecast track, the center will move across the central and northwestern Bahamas this weekend before approaching the southeast U.S. coast early next week. Formation chances remain high at 90 percent through both 48 hours and 7 days.
Hazards and Impacts
Wind: Tropical storm conditions are expected in the warning area beginning Saturday night, and possible in the watch area on Sunday.
Rainfall:
Eastern Cuba: 8 to 12 inches, with isolated amounts up to 16 inches.
Bahamas: 4 to 8 inches.
Hispaniola, Jamaica, and portions of Cuba: 2 to 4 inches.
Heavy rainfall will likely lead to flash flooding, urban flooding, and possible mudslides in higher terrain.
Storm Surge: Water levels could rise 1 to 3 feet above ground level in parts of the northwestern Bahamas, accompanied by large waves.
Surf: Swells from both this system and Hurricane Humberto will affect the Bahamas this weekend and reach the southeastern U.S. coast early next week, creating dangerous surf and rip current conditions.
U.S. Outlook
While it is too early to determine the exact track and strength of the system as it nears the southeast U.S. coast, there is an increasing risk of heavy rainfall, flooding, gusty winds, and storm surge impacts early next week from coastal Georgia through the southern Mid-Atlantic.
I’ll continue to track this system closely and provide updates as it strengthens and nears land.
