KEY WEST, Fla. -

A Cuban migrant who disappeared while trying to windsurf across the Florida Straits has been found adrift on his board.

The U.S. Coast Guard says a recreational boater found the man Thursday about 10 miles south of Big Pine Key.

Ensign Peter Bermont says the man was dehydrated and exhausted but otherwise uninjured.

Bermont says U.S. Citizenship and Immigration Services is investigating and will determine whether the man will be taken back to Cuba.

The man was one of three migrants who left Jibacoa, Cuba, on Tuesday. One made it to Key West more than nine hours later and told authorities that he lost sight of the others about 60 miles south of Key West.

The third migrant remains missing.
