A GALE WARNING FOR THE SOUTHERN GULF.
AS REFERENCED ABOVE, A FRONTAL BOUNDARY STALLS FROM NEAR CAPE
CANAVERAL, FLORIDA TO 24N88W WHERE IT TRANSITIONS TO A COLD FRONT
THAT CONTINUES TO NEAR VERACRUZ, MEXICO. STRONG TO GALE FORCE
WINDS AND ROUGH SEAS ARE BEHIND IT MAINLY S OF TAMPICO. AN ACTIVE

WILL SET UP IN THE W GULF TUE NIGHT AND WED, LOCALLY STRONG NEAR
THE YUCATAN. LOOKING AHEAD, ANOTHER COLD FRONT MAY REACH THE NW
GULF BY THU.
CARIBBEAN SEA...
THE PRESSURE GRADIENT BETWEEN A 1020 MB HIGH PRESSURE IN THE
ATLANTIC LOCATED NEAR 25N57W AND A 1009 MB LOW PRESSURE OVER
NORTHERN COLOMBIA IS SUSTAINING FRESH TRADES IN THE CENTRAL AND
EASTERN CARIBBEAN ALONG WITH MODERATE SEAS TO 6 FT. FRESH TO
STRONG E TO SE WINDS ARE IN THE NW BASIN, MAINLY OFF BELIZE AND IN
THE GULF OF HONDURAS ALONG WITH SEAS TO 6 FT. CONVECTION CONTINUES
TO FLARE-UP OVER THE YUCATAN PENINSULA ASSOCIATED WITH A PRE-
FRONTAL TROUGH. A LARGE AREA OF SHOWERS AND THUNDERSTORMS IS
EXTENDING FROM THE PENINSULA TO THE NW CARIBBEAN, AS WELL AS THE
YUCATAN CHANNEL. OTHERWISE, THE E PACIFIC MONSOON IS SUPPORTING
SCATTERED SHOWERS OFFSHORE COLOMBIA, PANAMA, COSTA RICA, AND
SOUTHERN NICARAGUA.
FOR THE FORECAST, THE PRESSURE GRADIENT BETWEEN HIGH PRESSURE
NORTH OF THE AREA AND THE COLOMBIAN LOW WILL SUPPORT FRESH TO
STRONG TRADES OVER THE S CENTRAL CARIBBEAN AND MODERATE TO FRESH
TRADES OVER THE REMAINDER OF THE E AND CENTRAL CARIBBEAN FOR THE
NEXT SEVERAL DAYS. THE SE FRESH TO STRONG WINDS OVER THE GULF OF
HONDURAS WILL DIMINISH ON SUN AS A WEAKENING COLD FRONT APPROACHES
THE YUCATAN CHANNEL. AFTER THE COLD FRONT DISSIPATES NEAR THE
YUCATAN CHANNEL ON MON, EXPECT SE WINDS OVER THE GULF OF HONDURAS
TO INCREASE TUE THROUGH THU.
ATLANTIC OCEAN...
A STATIONARY FRONT OFF OF THE SE UNITED STATES COAST EXTENDS FROM
31N77W TO CAPE CANAVERAL AND INTO THE GULF OF AMERICA. A BROAD
BAND OF SHOWERS AND TSTMS CONTINUE TO AFFECT THE CENTRAL AND

OFFSHORES. BROAD SURFACE RIDGING DOMINATES ELSEWHERE IN THE
SUBTROPICAL WATERS WHERE WINDS ARE MAINLY MODERATE OR WEAKER, EXC
EXCEPT FOR FRESH TO STRONG SW WINDS AHEAD OF THE FRONT. SEAS ARE
MODERATE BASIN-WIDE.

ALONG THE FRONTAL BOUNDARY TO BE JUST SOUTH OF BERMUDA TUE
MORNING WITH THE FRONT EXTENDING SOUTHWESTWARD TO THE CENTRAL
BAHAMAS. THE FRONT SHOULD BE DISSIPATING BY WED MORNING. EXPECT
FRESH TO STRONG SW WINDS SOUTH OF THE FRONT TONIGHT AND SUN,
FOLLOWED BY FRESH TO STRONG NE WINDS NORTH OF THE FRONT ON MON AND
TUE. LOOKING AHEAD, CONDITIONS SHOULD BECOME QUIESCENT TUE NIGHT
