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


GULF OF MEXICO...

A RIDGE LIES JUST N OF THE GULF COAST STATES...WITH TROUGHING 
OVER THE FAR SW GULF. THE PRESSURE GRADIENT BETWEEN THESE 
FEATURES IS MAINTAINING FRESH TRADE WINDS OVER MUCH OF THE GULF. 
THE RIDGE IS EXPECTED TO SHIFT E OVER THE NEXT 24 
HOURS...DIMINISHING THE WINDS OVER THE GULF. 

THE REMAINDER OF THE FORECAST IS DEPENDENT ON THE STRENGTH AND 
LOCATION OF TROPICAL STORM MATTHEW IN THE CARIBBEAN. THE 
OFFICIAL FORECAST BRINGS THE SYSTEM INLAND OVER BELIZE AND THE 
YUCATAN PENINSULA BY THE END OF THE WEEKEND...AND KEEPS THE 
SYSTEM OUT OF THE GULF OF MEXICO. HOWEVER...LOOK FOR WINDS AND 
SEAS TO INCREASE IN THE S CENTRAL GULF OVER THAT TIME FRAME AS A 
RESULT.

CARIBBEAN SEA...

TROPICAL STORM MATTHEW IS NEAR 14.0N78.4W AT 0300 UTC. THE 
OFFICIAL FORECAST HAS MATTHEW SKIRTING THE NORTH COAST OF 
HONDURAS THROUGH SAT...THEN REACHING BELIZE SUN NIGHT INTO 
MONDAY.

OVER THE REST OF THE CARIBBEAN...FRESH TO STRONG TRADES WILL 
PREVAIL THROUGH THE WEEKEND...THEN DIMINISH TO MODERATE TO FRESH 
EARLY NEXT WEEK AS MATTHEW MOVES OVER THE YUCATAN 
PENINSULA...AND THE PRESSURE GRADIENT ACROSS THE CARIBBEAN 
RELAXES.


SW N ATLC AND TROPICAL N ATLC...

RIDGING WILL REMAIN JUST N OF THE AREA THROUGH THE FORECAST 
PERIOD. MODERATE TO FRESH TRADES PREVAIL...WITH THE STRONGEST 
TRADES OVER THE SOUTHERN PORTION OF THE FORECAST AREA. AS 
MATTHEW MOVES INTO THE WESTERN CARIBBEAN AND BELIZE AND THE 
YUCATAN PENINSULA BY THE END OF THE WEEKEND...TRADES WILL 
DIMINISH ACROSS THE FORECAST AREA WITH A WEAKER PRESSURE 
GRADIENT.
