..SPECIAL FEATURES
CARIBBEAN GALE WARNING: THE PRESSURE GRADIENT BETWEEN HIGH PRESSURE
WELL NORTH OF THE REGION AND RELATIVELY LOWER PRESSURE IN NORTHERN
SOUTH AMERICA WILL LEAD TO GALE FORCE WINDS OFF NORTHWEST COLOMBIA
THROUGH EARLY THIS MORNING AND THEN AGAIN ON TONIGHT ALONG WITH
ROUGH SEAS. THIS GRADIENT WILL WEAKEN SOME EARLY THIS WEEK AS A
COLD FRONT MOVES INTO THE WESTERN ATLANTIC ALLOWING FOR THE
PULSING GALE CONDITIONS TO END MON.
PLEASE READ THE LATEST HIGH SEAS FORECAST ISSUED BY THE NATIONAL
HURRICANE CENTER AT WEBSITE -

GULF TUE NIGHT INTO WED AS THE FRONT WEAKENS.
..CARIBBEAN SEA
PLEASE READ THE SPECIAL FEATURES FOR INFORMATION ON AN
ONGOING GALE WARNING FOR OFFSHORE COLOMBIA.
ASIDE FROM THE GALE WARNING, THE PRESSURE GRADIENT BETWEEN BROAD
HIGH PRESSURE NORTH OF THE BASIN AND LOWER PRESSURES IN THE DEEP
TROPICS RESULTS IN FRESH TO NEAR GALE-FORCE EASTERLY TRADE WINDS
AND LOCALLY ROUGH SEAS IN THE CENTRAL CARIBBEAN AND GULF OF
HONDURAS. ELSEWHERE, MODERATE TO FRESH E TO SE WINDS AND SLIGHT TO
MODERATE SEAS PREVAIL.
FOR THE FORECAST, THE TIGHT PRESSURE GRADIENT BETWEEN THE 1030 MB HIGH
PRESSURE SYSTEM OVER THE N ATLANTIC AND LOWER PRESSURES IN THE
DEEP TROPICS WILL SUPPORT FRESH TO STRONG EASTERLY TRADE WINDS
WITH ROUGH SEAS IN THE SOUTH-CENTRAL CARIBBEAN THROUGH LATE NEXT
WEEK, INCLUDING THE GULF OF VENEZUELA. DURING THE NIGHTTIME HOURS
THROUGH TONIGHT, THESE WINDS ARE EXPECTED TO REACH GALE-FORCE OFF

SUPPORTING MODERATE TO FRESH EASTERLY TRADE WINDS SOUTH OF 25N AND
WEST OF 55W. SEAS IN THESE WATERS ARE 4-6 FT. MODERATE TO FRESH
NE-E WINDS AND SEAS OF 5-8 ARE NOTED SOUTH OF 25N AND EAST OF 55W.
ELSEWHERE, MODERATE OR WEAKER WINDS AND MODERATE SEAS ARE
