GULF OF MEXICO...
SCATTEROMETER DATA SHOWS NORTHERLY WINDS REACHING STRONG GALE 
FORCE OVER THE WESTERN GULF OF MEXICO TODAY...BEHIND A COLD 
FRONT EXTENDING FROM MOBILE BAY ALABAMA TO THE CENTRAL BAY OF 
CAMPECHE. WINDS SHOULD DROP BELOW GALE FORCE LATE TODAY AS THE 
FRONT PUSHES FURTHER EAST. THE FRONT STALLS THEN DISSIPATES SE 
OF THE GULF WATERS LATE TONIGHT/EARLY MONDAY. WINDS AND SEAS 
WILL DIMINISH ACROSS THE GULF THROUGH SUN AS HIGH PRES BUILDS 
OVER THE DEEP SOUTH STATES AND NORTHERN GULF. SOUTHERLY RETURN 
FLOW INCREASES OVER THE WESTERN GULF BY LATE TONIGHT AHEAD OF 
ANOTHER LOW PRES AREA MOVING INTO THE CENTRAL PLAINS. LOOKING 
AHEAD TO THE MIDDLE OF NEXT WEEK...GENERAL CONSENSUS IN THE 
MODEL GUIDANCE SHOWS THIS AREA OF SOUTHERLY WINDS EXPANDING INTO 
THE CENTRAL GULF AS THE LOW TO THE NORTH DEEPENS AND SHIFTS NE

CARIBBEAN WATERS...THEN WEAKENS AND LARGELY DISSIPATES. THE HIGH 
NE OF THE AREA SHIFTS FURTHER EAST AS THE FRONT MOVES OFF THE 
SOUTHEAST U.S. COAST. THIS WILL ALLOW THE TRADES OVER THE 
REMAINDER OF THE CARIBBEAN TO DIMINISH SUN INTO MON...ALTHOUGH 
WINDS OFF OF COLOMBIA NEVER REALLY DIMINISH MUCH BELOW 25 KT. 
THE SE WINDS OVER THE NW CARIBBEAN AND THE EASTERLY TRADES
