MARINE WEATHER DISCUSSION FOR THE GULF OF MEXICO...CARIBBEAN SEA 
AND SOUTHWEST NORTH ATLC S OF 31N W OF 55W.

A WEAK 1012 MB HIGH PRES IS CENTERED OVER THE NW GULF NEAR 
26N92W. A STATIONARY SURFACE TROUGH FROM 26N87W TO THE E BAY OF 
CAMPECHE. THE TROUGH SEPARATES THE SURFACE HIGH PRES FROM A 
RIDGE EXTENDING THROUGH THE STRAITS OF FLORIDA INTO THE SE GULF. 
BUOYS INDICATING GENERALLY LIGHT WINDS ARE ACROSS THE GULF. 
SOUTHERLY WINDS OVER THE SE GULF WILL INCREASE SLIGHTLY TUE AS 
THE TROUGH MOVES WESTWARD AND THE ATLC RIDGE AXIS BUILDS INTO 
THE SE GULF.

A SERIES OF COLD FRONTS MOVING N OF THE ATLC ZONE COMBINED WITH 
THE RIDGE ALONG 24N/25N WILL MAINTAIN A STRONG ENOUGH GRADIENT 
FOR 20-25 KT SW WINDS N OF AROUND 27N. THE RIDGE MOVES TO AROUND
27N TOWARD THE END OF THE WEEK AND WINDS DECREASE TO AROUND 
15-20 KT N OF 29N THU AND FRI. ELY WINDS INCREASE TO 20 KT THU
THROUGH SAT S OF 22N...OTHERWISE MOSTLY LIGHT WINDS ACROSS THE
AREA.

SURFACE RIDGE TO THE N OF THE CARIBBEAN HAS WEAKENED SLIGHTLY 
AND SHIFTED E ALLOWING WINDS TO DIMINISH OVER THE CARIBBEAN
COMPARED TO THE PAST FEW DAYS. THIS WILL BE FOR ONLY A BRIEF 
PERIOD AS THE RIDGE AXIS REBUILD THROUGH THE SOUTHERN BAHAMAS 
INCREASING THE TRADES TO 25 KT LATE TONIGHT. WINDS COULD 
POSSIBLY REACH 30 KT LATER IN THE WEEK ALONG THE SOUTH AMERICAN 
COAST.
