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

GULF OF MEXICO...ATLC HIGH PRES EXTEND ACROSS NRN GULF OF MEXICO 
BRINGING HEALTHY RETURN FLOW W OF 90W.  HIGH PRES WEAKENING IN 
RESPONSE TO UPPER LEVEL CYCLONIC VORTEX ALLOWING RETURN FLOW TO 
DIMINISH TEMPORARILY TODAY BEFORE INCREASING AGAIN LATE MON AND 
TUE.  TRPCL WAVE CROSSES YUCATAN PENINSULA TODAY ENTERING BAY OF 
CAMPECHE TONIGHT AND MON WITH PLENTY OF MOISTURE AVAILABLE FOR 
SCATTERED TSTMS.

SW N ATLC...SURFACE HIGH PRES 1022 MB HAS RIDGE ALONG 31N 
EXPECTED TO WEAKEN IN RESPONSE TO CYCLONIC VORTEX PRESENTLY AT 
25N75W DRIFTING W.  RESPONSIBLE FOR LIGHT WINDS N OF 26N BUT 
PRESSES GRADIENT S OF 26N WITH LOW PRES OVER CARIBBEAN RESULTING 
IN MODERATE TO STRONG E WINDS W OF BAHAMAS AND OVER STRAITS OF 
FLORIDA.  UPPER LEVEL CYCLONIC VORTEX HELPING ADVECT TRPCL 
MOISTURE INTO AN OTHERWISE VERY DRY BASIN.  WATER VAPOR IMAGERY 
SHOW MOISTURE ALONG S PERIPHERY OF VORTEX ADVECTING N AS CYCLONE 
DRIFTS W.  SURFACE ANALYSIS AND MODELS HAVE LOST SURFACE TROUGH 
...REFLECTION OF UPPER LEVEL CYCLONE...BUT WITH MOISTURE 
INCREASE ON SRN HALF OF BASIN IT WOULD NOT SURPRISE ME TO SEE 
FLARING UP OF DEEP CONVECTION WITHIN NEXT 24-36 HRS UNDER THE 
VORTEX DIFFLUENT WRN QUADRANTS.  

WEAKENED SURFACE HIGH PRES DRIFTS S BRINGING LIGHTER WINDS TO 
ENTIRE BASIN THEN STARTS REBUILDING INCREASING EASTERLY TRADES 
AND BUILDING SEAS MAINLY S OF 25N.  
 
TROPICAL N ATLC AND CARIBBEAN...TROPICAL WAVE ALONG 66W MOVE W 
AT 15 KT...6 DEG PER DAY...WITH ASSOCIATED WIND SHIFT AND 
SCATTERED TSTMS.  ANOTHER TROPICAL WAVE OVER GULF OF HONDURAS 
HAS INCREASED WINDS IN SURROUNDING WATERS BUT IS ABOUT TO MOVE 
INLAND EARLY THIS MORNING.  A THIRD WAVE SHOULD APPROACH TRPCL 
ATLC LATE IN PERIOD WITH SIMILAR WEATHER. 

WINDS ALONG COAST OF COLOMBIA REMAIN HIGHER DUE TO INFLUENCE OF 
LOW PRES 1009 MB.  NO SIGNIFICANT CHANGES EXPECTED THROUGH 
FORECAST PERIOD.
