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

GULF OF MEXICO...A FAIRLY WEAK PRESSURE PATTERN EXISTS OVER THE 
GULF. THE ATLC RIDGE IS ATTEMPTING TO REBUILD ALONG 28/29N... 
RESULTING IN LIGHT E TO SE WINDS OVER MOST OF THE WATERS. THE 
ONLY EXCEPTION IS IN THE EASTERN GULF...WHERE AN AREA OF SHOWERS 
AND THUNDERSTORMS HAS DEVELOPED...WITH SOME GUSTY WINDS ALONG 
OUTFLOW BOUNDARIES. THIS FEATURE SHOULD FIZZLE OUT OVERNIGHT. 
MODELS ARE DEPICTING A WEAK SFC WEAK TROUGH MIGRATING INTO THE 
SRN GULF TUE. THIS SHOULD CAUSE A SLIGHT INCREASE IN WINDS AND 
SEAS OVER SRN GULF WATERS TUE THROUGH WED.

SW N ATLC...A LOW PREVIOUSLY OFF THE GA/FL COAST HAS MOVED 
INLAND AND DISSIPATED. THE RIDGE AXIS DOMINATES THE WATERS E OF 
THE BAHAMAS WITH MODERATE SE TRADE WIND FLOW EXPECTED TO PERSIST 
THROUGH MON EVENING. ONSHORE FLOW S OF AN UPPER LOW CENTERED NEAR
28N78W GENERATED SOME MODERATE SHOWER ACTIVITY OVER THE BAHAMAS 
EARLIER TODAY BUT MOST OF THE HEAVIER SHOWERS ARE DYING OUT THIS 
AFTERNOON. TRADE WINDS SHOULD PICK UP A LITTLE S OF 23N TUE/WED 
AS A TROPICAL WAVE MOVES INTO THE ERN CARIBBEAN. 

CARIBBEAN AND TROPICAL N ATLC...OBSERVATIONS SHOW UP TO 20 KT E 
WINDS IN THE CENTRAL CARIBBEAN TODAY. THIS PATTERN WILL CONTINUE 
AND STRENGTHEN SOMEWHAT AHEAD OF A TROPICAL WAVE MOVING INTO THE 
ERN CARIBBEAN TUE/WED. WINDS WILL INCREASE AS WELL OVER TROPICAL 
N ATLC WATERS NE OF THE LESSER ANTILLES BY MIDWEEK AS THE WAVE 
MOVE THROUGH THE AREA.

.WARNINGS...
ATLC...NONE.
