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

ATLC...WEAK LOW PRES 1015 MB AT 28N60W EXPECTED TO DISSIPATE 
WITHIN 24 HRS AS IT DRIFTS NE AWAY FROM SW N ATLC.  ATLC 
ANTICYCLONE 1022 MB OVER CENTRAL ATLC WILL REBUILD WESTWARD TO 
80W ALONG 26N THROUGH FORECAST PERIOD.  WINDS TO REMAIN LIGHT 
OVER SW N ATLC BASIN.

CARIBBEAN...TRPCL WAVES WERE ALONG 34W...59W...79W AND 93W NONE 
OF WHICH ARE CLEARLY IDENTIFIED BY GLOBAL MODELS AS POTENTIAL TO 
GENERATE INTO TRPCL CYCLONES.  THE ONE ALONG 34W SEEMS THE MOST 
INTERESTING...SCHEDULED TO ENTER TRPCL ATLC BY WED AND CARIBBEAN 
ON THU...BUT SHEARING ENVIRONMENT ALOFT REMAINS HOSTILE.  

AREA OF CYCLONIC VORTICITY S OF 15N EMBEDDED IN TRPCL WAVE ALONG 
79W...BUT ITS W DRIFT LIKELY TO BRING IT OVER CENTRAL AMERICA 
BEFORE IT HAS A CHANCE TO DEVELOP. GLOBAL MODELS DO NOT SHOW ANY 
SIGNIFICANT DEVELOPMENT IN CARIBBEAN THROUGH FORECAST PERIOD.  
ONLY INCREASE IN WINDS ALONG BASIN IS RELATED TO TRPCL WAVES 
CROSSING.

GULF OF MEXICO...
HIGH PRES RIDGE ALONG GULF COAST COASTAL WATERS BLOCKS WEAK 
FRONTAL BOOUNDARY FROM ENCROACHING INTO WRN GULF WATERS ALLOWING 
ONLY MINOR WIND SHIFTS OVER CERNTRAL AND ERN GULF BUT LITTLE IN 
WAY OF INCREASE WIND ABOVE MODERATE OR BUILDING SEAS ABOVE 4 FT.
