..GULF OF MEXICO
REFER TO THE SECTION ABOVE FOR DETAILS ON THE GALE WARNING IN
EFFECT FOR THE NORTHERN GULF WATERS.
A RIDGE EXTENDS FROM HIGH PRESSURE IN THE WESTERN ATLANTIC
ACROSS THE GULF COAST STATES. THE PRESSURE GRADIENT BETWEEN THE
AREA OF HIGH PRESSURE AND 998 MB LOW PRESSURE OVER SW TEXAS IS
SUPPORTING FRESH TO STRONG WINDS ACROSS THE GULF WATERS W OF
87W. MODERATE TO FRESH WINDS ARE NOTED E OF 87W, EXCEPT IN THE
BAY OF CAMPECHE WHERE WINDS ARE GENTLE TO MODERATE. SEAS ARE IN
THE 8-11 FT RANGE W OF 88W, AND 5-7 FT ELSEWHERE, EXCEPT OVER
THE E GULF E OF 83W WHERE 2-4 FT SEAS ARE NOTED.
FOR THE FORECAST, THE AFOREMENTIONED HIGH OVER THE WESTERN

CARIBBEAN FROM 16N62W TO 17N71W, THEN IT BECOMES STATIONARY TO N
OF JAMAICA. THE PRESSURE GRADIENT BETWEEN THE AREA OF HIGH
PRESSURE AND THE COLOMBIAN LOW IS SUPPORTING NEAR-GALE FORCE
WINDS OFF THE COASTS OF COLOMBIA AND VENEZUELA AND FRESH TO
STRONG WINDS OVER THE CENTRAL CARIBBEAN, INCLUDING THE WINDWARD
PASSAGE. THE PRESSURE GRADIENT ALSO SUPPORTS FRESH TO STRONG
WINDS ACROSS THE GULF OF HONDURAS. MODERATE TO FRESH WINDS ARE
NOTED ELSEWHERE ACROSS THE CARIBBEAN WATERS. SEAS ARE IN THE 8-
10 FT RANGE IN THE SOUTH CENTRAL CARIBBEAN, 6-8 FT OVER THE

WESTERN PORTION OF THE BASIN, EXCEPT FOR THE GULF OF HONDURAS
WHERE SEAS ARE 6-9 FT. ELSEWHERE, SEAS ARE IN THE 2-4 FT RANGE.
FOR THE FORECAST, THE PRESSURE GRADIENT BETWEEN HIGH PRESSURE
ACROSS THE WESTERN ATLANTIC AND LOW PRESSURE OVER COLOMBIA WILL
SUPPORT FRESH TO STRONG WINDS ACROSS MOST OF THE CENTRAL
CARIBBEAN, PULSING TO NEAR GALE-FORCE AT NIGHT OFF OF COLOMBIA
THROUGH THE NEXT SEVERAL NIGHTS. THE AREA OF HIGH PRESSURE WILL
ALSO SUPPORT FRESH TO STRONG WINDS IN THE WINDWARD PASSAGE,
SOUTH OF HISPANIOLA, AND IN THE GULF OF HONDURAS. WINDS WILL
START TO DIMINISH THE END OF THE WEEK AS THE HIGH PRESSURE
SHIFTS EASTWARD AND WELL NE OF THE REGION. LOOKING AHEAD, A COLD
FRONT IS EXPECTED TO REACH THE YUCATAN CHANNEL THU NIGHT, THEN

27N BETWEEN 32W AND 36W. ROUGH TO VERY ROUGH SEAS PREVAIL NEAR
THE FRONT BETWEEN 36W-66W. THE LARGER SEAS ARE NW OF THE FRONT.
OUTSIDE OF THE GALES OFF AFRICA, FRESH TO STRONG WINDS ARE NOTED
FROM 15N TO 31N AND E OF 27W. ELSEWHERE, GENTLE TO MODERATE
WINDS GENERALLY PREVAIL. OUTSIDE OF THE LARGE SEAS IN THE
VICINITY OF THE GALES OFF AFRICA AND NEAR THE FRONT DESCRIBED
