A tropical cyclone is forecast to move across the northwestern Bahamas in the coming days.
Reuters reports the storm could potentially bringing more rain and wind to islands already reeling from Hurricane Dorian.
The Miami-based U.S. National Hurricane Center issued the warning on Thursday.
The NHC says the system could become a tropical depression or storm before making landfall as early as Friday.
Affected areas include Abacos, Berry Islands, Bimini, Eleuthera, Grand Bahama Island and New Providence.
