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

GULF OF MEXICO...
WEAK SURFACE TROUGH EXTENDS ROUGHLY ACROSS THE STRAITS OF 
FLORIDA INTO THE SE GULF WITH ISENTROPIC LIFTING CAUSING 
WIDESPREAD RAIN SHOWERS S OF 28N E OF 87W EXTENDING ACROSS S 
FLORIDA. A WEAK AREA OF LOW PRES APPEARS TO HAVE FORMED ALONG 
THE TAIL END OF THE TROUGH BUT THIS FEATURE IS NOT EXPECTED TO 
HANG AROUND FOR VERY LONG. OTHERWISE...HIGH PRES OVER THE 
CAROLINAS IS IN CONTROL AND IS PRODUCING GENERALLY 
LIGHT/MODERATE E TO SE FLOW. THE HIGH WILL SLIDE E OVER THE NEXT 
FEW DAYS BEFORE RE-INFORCING HIGH PRES BUILDS OVER THE SE U.S. 
ON WED. THIS WILL CAUSE WINDS TO INCREASE OVER THE E GULF WED 
AND THU WITH SEAS BUILDING ESP. IN THE STRAITS OF FLORIDA WHERE 
THE WINDS WILL BE AGAINST THE CURRENT. A WEAK COLD FRONT IS 
EXPECTED TO MOVE OFF THE TEXAS COAST THU.

CARIBBEAN AND TROPICAL ATLC...
HIGH PRES N OF THE AREA CONTINUES TO PRODUCE FRESH/MODERATE ELY 
TRADES WITH HIGHEST WINDS ALONG THE COLOMBIAN COAST. THE 
GRADIENT RELAXES A BIT ON MON WITH WINDS DECREASING JUST A BIT. 
WAVEWATCH GUIDANCE CONTINUES TO HAVE A HIGH BIAS REGARDING 
SWELLS OVER THE ATLC...FRENCH BUOY 41100 IS REPORTING 8 FT WITH 
WAVEWATCH INDICATING 10-11 FT SEAS. HAVE THEREFORE OPTED TO GO 
WITH FNMOC WAVE GUIDANCE WHICH SEEMS TO HAVE A GOOD HANDLE ON 
THE WAVE FIELD.

SW N ATLC...
N PART OF BOUNDARY STRETCHED ACROSS THE W ATLC IS NOW MOVING E 
AS A COLD FRONT WITH A PUSH OF HIGH PRES SCOOTING OFF THE E 
COAST OF THE US. SRN PART OF THE BOUNDARY ACROSS THE BAHAMAS TO 
THE STRAITS OF FLORIDA IS DIFFUSE AND STATIONARY WITH LITTLE 
WIND SHIFT NOTED. THE COLD FRONT SHIFTS E OF 65W BY SUN 
AFTERNOON THEN HIGH PRES TO THE N INCREASES THE GRADIENT AND 
PRODUCES NE/E WINDS 15-20 KT NE OF THE BAHAMAS. THESE WINDS LAST 
UNTIL LATE TUE WHEN GRADIENT RELAXES. A COLD FRONT/RE-INFORCING 
HIGH MOVES S INTO THE AREA EARLY WED WITH WINDS INCREASING TO 
20-25 KT AND SPREADING W ACROSS THE N BAHAMAS AND S FLORIDA. THE 
BAND OF STRONGEST WINDS SHIFTS S OF 27N BY THU AS THE CENTER OF
