THE GULF OF MEXICO...
THE GULF CONTINUES TO BE INFLUENCED BY A 1024 MB HIGH PRESSURE 
SYSTEM CENTERED OVER THE FAR WESTERN ATLANTIC NEAR 30N75W. THIS 
FEATURE IS BRINGING SOUTHWEST WINDS 10-15 KT ACROSS THE ENTIRE 
BASIN. THEREFORE...FAIR WEATHER IS OBSERVED OVER MOST OF THE 
REGION EXCEPT FOR AN AREA OF BROKEN LOW CLOUDS OVER THE WESTERN 
GULF...WEST OF 95W. CONDITIONS ARE EXPECTED TO REMAIN CONSTANT 
OVER THE NEXT 24 HOURS...AS THE SURFACE HIGH OVER THE FAR 
WESTERN ATLANTIC WOBBLES NEAR 30N75W.    

THE CARIBBEAN SEA...
MARINE OBSERVATIONS SHOW FRESH TO STRONG EASTERLY WINDS ACROSS 
THE CARIBBEAN SEA. SATELLITE IMAGERY SHOWS BROKEN TO OVERCAST 
LOW CLOUDS WITH POSSIBLE SCATTERED SHOWERS OVER THE CENTRAL 
BASIN FROM 13N TO 16N BETWEEN 67W AND 74W...AND WITHIN 200 NM 
OFF THE COAST OF COSTA RICA AND NICARAGUA. THE REMAINDER OF THE

IMAGERY. OVER THE NEXT 24 HOURS LOOK FOR THE SHOWER ACTIVITY TO 
SPREAD OVER THE SOUTHERN CARIBBEAN SOUTH OF 14N.   

THE ATLANTIC OCEAN...
A 1024 MB HIGH IS CENTERED OVER THE FAR WESTERN ATLANTIC NEAR 
30N75W PRODUCING STRONG SUBSIDENCE OVER MOST OF THE WESTERN

CENTER OVER THE NEXT 24 HOURS...KEEPING THE FAIR WEATHER IN THIS 
REGION. A DEEP LAYERED TROUGH IS OVER THE CENTRAL ATLANTIC 
SUPPORTING A 1004 MB OCCLUDED LOW NEAR 32N48W. THIS LOW IS 
MERGING WITH A SECONDARY LOW NEAR 38N45W. A COLD FRONT FROM THE 
SECONDARY LOW ENTERS THE DISCUSSION AREA NEAR 32N40W AND EXTENDS 
SOUTH-SOUTHWEST ALONG 25N43W 20N48W 15N57W. SCATTERED SHOWERS 
ARE WITHIN 60 NM OF THE FRONT NORTH OF 24N. ELSEWHERE EAST OF
