TAVERNIER, Fla. (AP) _ Visitors were ordered to leave the Florida Keys on Sunday and Gov. Jeb Bush issued a state of emergency because of the possibility that Hurricane Ernesto could threaten the state.

Bush's order came after the Monroe County Emergency Management office told tourists to postpone any immediate plans to travel to the Keys and ordered those already in the island chain to leave.

All travel trailers and recreational vehicles were ordered off the islands immediately.

Ernesto, the first hurricane of the Atlantic season, was lashing Haiti on Sunday with heavy rain and sustained wind of 75 mph.

The storm was expected to move over Cuba, then bring rain and wind to southern Florida by early Tuesday, the National Hurricane Center said.
