A large area of cloudiness, showers and a few thunderstorms over the northwestern Caribbean Sea stretching into the  southwestern Atlantic Ocean is associated with a surface trough.

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 South Florida.

This system has a low chance (10 percent) of becoming a tropical cyclone over the next 48 hours as it moves northwestward at 5 to 10 mph., according to the National Hurricane Center.
