A large area of cloudiness, showers and thunderstorms over the northwestern Caribbean Sea and extending northward across the Straits of Florida and The Bahamas is associated with a surface trough.
According to the National Hurricane Center (NHC) in Miami, although upper-level conditions are not expected to be particularly conducive for development of this system, areas of heavy rainfall are likely during the next couple of days over the Cayman Islands, Cuba, The Bahamas and southern Florida.
This system has a low chance -- 10 percent -- of becoming a tropical cyclone during the next 48 hours as it moves northwestward at 5 to 10 mph, the NHC said.
