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

GULF OF MEXICO...
COLD FRONT CONTINUES TO SWEEP SE OVER THE GULF AND AS OF 18 UTC 
HAS CLEARED JUST ABOUT THE ENTIRE GULF WITH WINDS SHIFTING TO 
THE NW IN THE YUCATAN CHANNEL. BUOYS ARE REPORTING GENERALLY NW 
TO N WINDS OF 20-25 KT BEHIND THE FRONT. BUOY 42055 IN THE BAY 
OF CAMPECHE IS REPORTING NLY WINDS OF 20 KT AND 13 FT SEAS. 
THIS IS REPRESENTATIVE OF THE CONDITIONS IN THE SW GULF AND WILL 
THEREFORE ALLOW THE GALE WARNING FOR THE SW GULF TO EXPIRE 
EFFECTIVE AT 18 UTC. WINDS CONTINUE TO DECREASE AND VEER TO THE
NE TO E TONIGHT AND THEN TO THE SE W OF 90W ON SUN. A WEAK AREA 
OF LOW PRES DEVELOPS ALONG THE W GULF COAST AND ATTEMPTS TO DRAG 
A MUCH WEAKER COLD FRONT INTO THE NW GULF ON MON. THIS FRONT 
STALLS ALONG THE COAST MON NIGHT AND IS LIFTED BACK N AS A WARM 
FRONT ON TUE AHEAD OF DEVELOPING LOW PRES OVER THE SRN PLAINS. 
LOW PRES MOVES E THROUGH THE OHIO VALLEY AND FINALLY BRINGS 
A STRONGER COLD FRONT INTO THE NW GULF ON WED. THE FRONT EXTENDS 
FROM THE FL PANHANDLE TO TAMPICO BY LATE WED AND STALLS FROM 
SW FLORIDA TO 25N90W TO TAMPICO BY LATE THU. LARGE HIGH PRES 
BUILDS N OF THE FRONT WED INTO THU WITH N TO NE WINDS OF 20-25 
KT N OF THE FRONTAL BOUNDARY. 

SW N ATLC...
AS LOW PRES REFORMS OFF THE NC COAST/VA CAPES THE COLD FRONT HAS
STARTED TO SWEEP EASTWARD AND CURRENTLY EXTENDS FROM 31N77W TO
THE E COAST OF FLORIDA NEAR MELBOURNE. NW WINDS OF 20-25 KT ARE 
EXPECTED NW OF THE FRONT INTO TONIGHT. THE FRONT SWEEPS E AND 
EXTENDS FROM 29N65W TO SE FLORIDA BY LATE SUN WITH WINDS VEERING 
TO THE NE AND DROPPING OFF TO 15-20 KT. THE FRONT DISSIPATES 
INTO AN E-W FRONTAL TROUGH WHICH LIES ALONG 28N MON AND TUE. 
THE W PORTION OF THE FRONTAL TROUGH LIFTS NWD AS A WARM FRONT 
TUE NIGHT AND WED WITH S TO SW WINDS INCREASING TO 20-30 KT N OF 
28N ON WED AND CONTINUING INTO EARLY THU. THE NEXT FRONT IS 
SLATED TO EMERGE OFF THE SE COAST THU AND EXTEND FROM 30N70W TO
SE FLORIDA BY LATE THU. THIS FRONT IS EXPECTED TO BE SOMEWHAT 
WEAKER THAN THE CURRENT FRONT.   

CARIBBEAN AND TROPICAL N ATLC...
COLD FRONT NOW ENTERING THE YUCATAN CHANNEL SLIGHTLY FASTER 
THAN PROGGED. THE FRONT WILL MAKE LITTLE HEADWAY INTO THE NW 
CARIBBEAN AND EXTEND FROM NW CUBA TO THE NE COAST OF THE YUCATAN 
ON SUN. THE FRONT DISSIPATES LATE SUN. OTHERWISE...STRENGTH OF 
HIGH PRES OVER SW N ATLC AND LOWER PRES OVER SOUTH AMERICA 
SUPPORTS FRESH TRADES ACROSS MOST OF THE CARIBBEAN WITH STRONGER 
WINDS ALONG COAST OF COLOMBIA THROUGH ENTIRE FORECAST PERIOD.
