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

GULF OF MEXICO...
A WEAK 1018 MB HIGH PRES CENTER LOCATED NEAR 27N88W...HAS A 
RIDGE COVERING MUCH OF THE AREA WITH MAINLY GENTLE BREEZE AND 
LIGHT SEAS...PARTICULARLY OVER THE E HALF OF THE GULF. SE WINDS  
OF 10 TO 15 KT...AND SEAS GENERALLY UNDER 5 FEET ARE NOTED OVER 
THE W HALF OF THE GULF REGION. A SFC TROUGH OVER THE W CARIBBEAN 
ALONG 86W WILL CONTINUE TO DRIFT WWD. SEE THE CARIBBEAN SEA 
SECTION FOR MORE DETAILS. OTHERWISE...A VERY DRY AIR MASS IS IN 
PLACE LIMITING THE DEVELOPMENT OF ANY SIGNIFICANT CONVECTION.   

CARIBBEAN AND TROPICAL N ATLC W OF 55W...
A TROPICAL WAVE AND A PAIR OF SURFACE TROUGHS ARE AFFECTING THE 
CARIBBEAN SEA THIS AFTERNOON. THE TROPICAL WAVE IS ALONG 70W AND 
WILL MOVE WWD AT 10 TO 15 KT REACHING 85W WED. A SURFACE TROUGH 
OVER THE CENTRAL CARIBBEAN NEAR 78W WITH MODERATE TO STRONG 
CONVECTION WILL MOVE TO 83W MON...REACHING 88W TUE. A SECOND 
WEAK SURFACE TROUGH REMAINS NEAR THE YUCATAN COAST AND WILL 
CONTINUE TO DRIFT WWD. ACCORDING TO THE COMPUTER MODELS...THESE 
TROUGHS ARE EXPECTED TO MERGE LATE MON INTO TUE NEAR THE COAST 
OF THE YUCATAN PENINSULA. SE WINDS OF 20 KT AND SEAS TO 8 FT 
WILL FOLLOW THE TROUGH. 

SUBTROPICAL ATLC W OF 65W...    
A DEEP LAYERED TROUGH REMAINS THE MAIN FEATURE IN SW N ATLC 
EXTENDING SW INTO THE FAR WESTERN CARIBBEAN. THIS TROUGH IS 
HELPING TO INDUCE SOME SHOWER ACTIVITY  MAINLY BETWEEN 60W AND 
67W. A SFC TROUGH CLIPS THE NW CORNER OF THE AREA WITH ISOLATED 
TSTMS. SCATTERED TSTMS ARE ALSO DEVELOPING OVER THE NW AND 
CENTRAL BAHAMAS AND COASTAL WATERS. A 1024 MB SURFACE HIGH OVER 
CENTRAL ATLC NEAR 29N53W EXTENDS A RIDGE SW TO THE STRAITS OF 
FLORIDA. THE RIDGE WILL PERSIST ALONG 27N THROUGH THU. A LOW 
PRES SYSTEM WILL DEVELOP OFF THE COAST OF THE CAROLINAS TUE AND 
WED INCREASING SW FLOW N OF 28N. THE ASSOCIATED COLD FRONT WILL 
ENTER THE N WATERS TUE NIGHT INTO WED. NE SWELL IN THE WAKE OF 
THE FRONT WILL SPREAD ACROSS THE N WATERS RAISING SEAS TO 8 FT.
