well if that local Met went by the Miami NWS marine forecas you could see why he may have made that forecast--here is an excerpt-
MARINE...LIGHT TO MODERATE EASTERLY FLOW WILL CONTINUE THROUGH
MONDAY... WITH WIND GRADUALLY BACKING AROUND TO NORTHEAST AND
FINALLY MOSTLY NORTHERLY BY WEDNESDAY AND THURSDAY. T.D. 10 IN THE
FAR SOUTHEAST CARIBBEAN IS FORECAST TO MOVE WEST NORTHWEST FOR 24 TO
48 HOURS THEN TURN MORE NORTHWEST AND LIE BETWEEN JAMAICA AND THE
SOUTH COAST OF CUBA BY TUESDAY EVENING. NHC IS FORECASTING IT TO
STRENGTHEN TO TROPICAL STORM STRENGTH... AND FINALLY TO HURRICANE
STRENGTH TUESDAY OR WEDNESDAY... AND PROBABLY MOVE ACROSS EASTERN
CUBA AND THE CENTRAL BAHAMAS AFTER THAT. ANYONE PLANNING PLEASURE
BOATING TOWARD THE BAHAMAS... OR TAKING A CRUISE SHOULD PAY CLOSE
ATTENTION TO THE PROGRESS OF THIS SYSTEM. DEPENDING ON HOW CLOSE TO
SOUTH FLORIDA IT EVENTUALLY PASSES... WE COULD BE UNDERESTIMATING
THE WIND SPEEDS WEDNESDAY AND THURSDAY.
