110 AM EST THU NOV 23 2006

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

GULF OF MEXICO...
THE STRONG AREA OF LOW PRES OFF THE CAROLINA COAST IS SLOWLY 
PULLING NE AND IS ALLOWING FOR WINDS AND SEAS OVER THE E GULF TO 
GRADUALLY DIMINISH. A 1025 MB HIGH IS CENTERED OVER THE NW GULF 
WITH RIDGING EXTENDING FROM THE SW GULF THROUGH THE LOWER MS 
VALLEY. WINDS REMAIN OUT OF THE N AT 15 KT OVER THE E AND MIDDLE 
GULF ZONES...AND SEAS HAVE DROPPED WITH THE HIGHEST REPORT OF 8 
FT AT THE E GULF BUOY 42003. THE PATTERN SHOULD REMAIN FAIRLY 
CONSISTENT THROUGH MON WITH A RIDGE CONTINUING FROM THE SE U.S. 
TO THE SW GULF...ALTHOUGH WINDS WILL BEGIN TO INCREASE OUT OF 
THE NE OVER THE SE GULF AND STRAITS OF FL LATE FRI AS THE 
GRADIENT TIGHTENS. WITH WINDS EXPECTED TO INCREASE TO 20 KT 
AGAINST THE GULF STREAM IN THE STRAITS...SEAS COULD POTENTIALLY 
BUILD TO 8 OR 9 FT SAT THROUGH MON.

CARIBBEAN AND TROPICAL N ATLC...
A STATIONARY FRONT REACHES FROM HAITI TO ERN PANAMA AND IS 
BOUNDED BY A STRONG HIGH PRES TO ITS W...WHICH CONTINUES TO 
PRODUCE STRONG 25-30 KT NLY WINDS OVER THE SW CARIBBEAN W OF 78W 
TO THE NICARAGUAN COAST. THESE WINDS ARE EXPECTED TO SLOWLY 
DECREASE TO 20-25 KT BY THIS AFTERNOON AND THEN GRADUALLY WEAKEN 
BELOW 20 KT THROUGH SUN AS THE FRONT RETROGRADES A BIT TO THE W. 
BUOY 42057 IS REPORTING SEAS TO 9 FT...WHICH MATCHES WHAT IT 
SHOWN IN NWW3 GUIDANCE. WHILE I HAVE NO WAVE OBS FROM SHIPS OVER 
THE SW CARIBBEAN...NWW3 CONTINUES TO SHOW SEAS TO 14 FT OFF THE 
COSTA RICAN COAST WITH A HEALTHY NLY SWELL. SEAS ARE EXPECTED TO 
FALL BELOW 8 FT BY SAT MORNING AS THE WINDS DIE DOWN. WINDS 
ACTUALLY DON'T DIMINISH AS FAST OVER THE NW CARIBBEAN AS THE 
PRES GRADIENT INCREASES OVER THE E GULF OF MEXICO. 
ELSEWHERE...THE DEPENDABLE TRADES CONTINUE OVER THE E CARIBBEAN 
AND TROPICAL N ATLC WATERS BUT SHOULD START A STEADY BUT GRADUAL 
WEAKENING TREND THROUGH MON. EASTERLY ATLC SWELLS WILL KEEP SEAS 
TO 8-9 FT E OF THE ISLANDS BUT SHOULD SUBSIDE BEGINNING FRI 
NIGHT/SAT.

SW N ATLC...
A STRONG 1007 MB LOW OFF THE CAROLINAS IS MOVING SLOWLY NE 
TOWARD THE MID-ATLC STATES WITH A STATIONARY FRONT LOCATED TO 
THE E FROM 31N68W TO HAITI. A SWATH OF 20-25 KT WINDS CONTINUES 
TO BRUSH ACROSS THE NW CORNER OF THE ZONE ON THE UNDERBELLY OF 
THE LOW...BUT THIS SHOULD DIE OFF BY AFTERNOON AS THE LOW LIFTS 
N. THE FRONT MOVES LITTLE THROUGH FRI BUT THEN REALLY LOSES ITS 
IDENTITY INTO SAT AFTER LOSING ITS UPPER LEVEL SUPPORT. HIGH 
PRES BUILDS E BEHIND THE FRONT FRI THROUGH MON AND INCREASES 
WINDS TO 20 KT. A FAIRLY GOOD FETCH OF 15-20 KT NELY WINDS SETS 
IN DURING THIS PERIOD FROM N OF BERMUDA TO THE FLORIDA/BAHAMAS 
COASTS WITH SEAS BUILDING TO 8 FT IN SWELLS WITH 8-9 SEC PERIODS.
