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

SW N ATLC...
SUBTROPICAL RIDGE CONTINUES TO DOMINATE THE PICTURE...EXTENDING FROM 
31N60W TO SE FLORIDA...CLOSE TO ITS CLIMATOLOGICAL POSITION. RIDGE 
AXIS WILL BEGIN TO SHIFT SLIGHTLY NWD SUN...SETTING UP ALONG 31N MON 
THROUGH WED WITH WINDS BECOMING E/SE OVER THE ENTIRE AREA.

CARIBBEAN AND TROPICAL N ATLC...
QUIKSCAT SHOWS SIZE OF 30 KT WIND AREA SHRINKING CONSIDERABLY OVER 
THE PAST 24-48 HOURS. EXPECT SUBSEQUENT SCATTEROMETER PASSES TO 
CONTINUE THIS TREND AND HAVE LOWERED WINDS AND SEAS IN THE FORECAST 
AS A RESULT. AS THE ATLC RIDGE BEGINS TO SHIFT SLIGHTLY N SUN THE 
TRADES ARE EXPECTED TO DIMINISH EVEN FURTHER AND SHOULD REACH THEIR 
WEAKEST POINT MON WITH ONLY 15-20 KT OVER THE CENTRAL CARIBBEAN. SEAS
WILL ALSO SUBSIDE TO 6-8 FT IN THAT AREA.

A TROPICAL WAVE ENTERING THE TROPICAL N ATLC WILL INCREASE WINDS TO 
15-20 KT SUN NIGHT THROUGH WED E OF THE LESSER ANTILLES. THE WAVE 
WILL MOVE INTO THE E CARIBBEAN SUN. WINDS WILL ONCE AGAIN INCREASE 
OVER THE AREA TUE AND WED...JUST AFTER THE BRIEF RESPITE ON MON.

GULF OF MEXICO...
WEAK HIGH PRES RIDGE EXTENDS W ACROSS THE NORTHERN GULF FROM CENTRAL 
FLORIDA. WINDS REMAIN LIGHT ACROSS THE AREA. THE AXIS WILL BEGIN TO 
SHIFT SLOWLY NWD ON SUN EVENTUALLY SETTING UP ALONG 30N/31N TUE AND 
WED. A MID/UPPER LOW WILL BECOME CUT-OFF OVER SE TEXAS SUN THROUGH 
WED WHICH WILL LIKELY PRODUCE A SURFACE TROUGH INLAND...AND ALLOW 
ONSHORE WINDS TO 15 KT ALONG THE TEXAS COAST DURING THAT PERIOD.
