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

THE COMBINATION OF HIGH PRES THE WESTERN ATLC AND LOWER PRES 
OVER THE SOUTHERN PLAINS IS PRODUCING A TIGHT PRES GRADIENT OVER 
THE GULF OF MEXICO RESULTING IN INCREASING WINDS AND SEAS. 
EXPECT SELY WINDS IN THE 20 TO 25 KT RANGE ACROSS MUCH OF THE 
GULF THROUGH FRI. HOWEVER THE GRADIENT WILL NOT BE AS TIGHT OVER 
THE NE GULF WITH WINDS LIGHTER IN THIS AREA. THESE CONDITIONS 
WILL SUBSIDE ALL SECTIONS EXCEPT THE FAR SE PORTION THROUGH SAT 
AND SUN.

DISSIPATING ATLC STATIONARY FRONT EXTENDS FROM 26N65W TO 23N75W 
WILL BECOME DIFFUSE THIS MORNING AS A LARGE AREA OF HIGH PRES 
BUILDS SE ACROSS THE REGION. AS A RESULT THE PRES GRADIENT WILL 
TIGHTEN ALLOWING FOR WINDS TO INCREASE AND SEAS TO BUILD 
PRIMARILY OVER THE SOUTHERN PORTION OF THE AREA  THROUGH SAT
WITH MOSTLY LIGHT WINDS OVER ALL BUT THE FAR S PORTION OF THE
AREA ON SUN.

AS THE ATLC HIGH PRES BUILDS TO THE N STRONG WINDS WILL PERSIST 
ACROSS MOST OF THE CARIBBEAN...THE EXCEPTION BEING THE FAR 
EASTERN CARIBBEAN. THE STRONGEST WINDS...TO 30 KT...WILL BE
IN THE TYPICAL AREAS ALONG THE COAST OF COLOMBIA. THE WINDS WILL
WEAKEN SOME OVER THE WEEKEND AS THE HIGH WEAKENS...WITH WINDS
IN THE 15-20 KT RANGE OVER THE CENTRAL CARIBBEAN AND LESS THEN
20 KT ELSEWHERE ON SUN.
