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

A DISSIPATING STATIONARY FRONT IN THE GULF OF MEXICO EXTENDS 
FROM TAMPA BAY TO S TEXAS. THE BOUNDARY WILL LIKELY REMAIN 
STATIONARY TODAY THEN DISSIPATE TONIGHT. BUOYS ARE CURRENTLY 
REPORTING LIGHT WINDS ACROSS THE AREA...10 KT OR LESS...WITH 
SEAS 1 TO 2 FT. NWW3 SHOWS WINDS AND SEAS REMAINING LOW THROUGH 
THE WEEKEND. SLY RETURN FLOW AND SEAS INCREASING LATE SUN INTO 
EARLY NEXT WEEK IN THE WRN GULF AS HIGH PRES BECOMES ESTABLISHED 
OVER THE SE U.S.

SWELLS IN THE ATLC FROM WHAT WAS ONCE HURRICANE FLORENCE 
CONTINUE TO SUBSIDE. BUOYS OFF THE N COAST OF FLORIDA INDICATE 
SWELLS OF AROUND 6 FT. THIS IS IN GOOD AGREEMENT WITH THE NWW3 
OUTPUT. THE SWELLS WILL CONTINUE TO SUBSIDE TONIGHT THROUGH MON. 
COLD FRONT HAS ENTERED THE NW CORNER OF THE AREA FROM 31N76W TO 
CENTRAL FLORIDA. ONLY LIGHT NWLY WINDS AND SEAS EXIST BEHIND THE 
FRONT. THE FRONT WILL CONTINUE TO SLIDE ACROSS THE N PORTION OF 
THE AREA THROUGH MON AS HIGH PRES BUILDS OVER SE U.S. COAST 
THROUGH TUE. TROPICAL STORM HELENE OVER THE EASTERN ATLC MOVING 
TO THE WNW...THE NWW3 INDICATES THAT 6 TO 8 FT SWELLS COULD MOVE 
INTO THE FAR E PORTION OF THE ZONE BY TUE AS HELENE MOVES JUST E 
OF THE AREA AS A HURRICANE AT THAT TIME.

TRADES ARE GENERALLY RUNNING IN THE 15 TO 20 KT RANGE IN THE 
CENTRAL AND E CARIBBEAN. THE WINDS INCREASE TO 20 TO 25 KT OVER 
THE WEEKEND AS THE ATLC RIDGE STRENGTHENS. THE GRADIENT RELAXES 
A BIT EARLY NEXT WEEK WITH WINDS AND SEAS GRADUALLY SUBSIDING. 
TROPICAL STORM HELENE HAS BEEN SLOWLY STRENGTHENING. THIS STORM 
IS CURRENTLY EXPECTED TO REMAIN JUST TO THE E/NE OF THE 
AREA...BUT WINDS AND SEAS WILL INCREASE AS HELENE NEARS THE AREA 
WITH ITS CLOSEST APPROACH EXPECTED ON MON AND TUE. THE FORECAST 
IS VERY DEPENDENT ON THE TRACK AND INTENSITY OF HELENE AND THIS 
WILL BE FINE TUNED IN THE COMING DAYS.
