GULF OF AMERICA GALE WARNING:
A STRONG COLD FRONT IS EXPECTED TO ENTER THE NW GULF BY SUN

WEEK, GALE-FORCE NW WINDS WILL DEVELOP IN THE WAKE OF THE FRONT
MAINLY W OF 94W. ROUGH SEAS ARE EXPECTED WITH THESE WINDS. THESE
CONDITIONS WILL DISSIPATE BY LATE MON.
PLEASE REFER TO THE LATEST HIGH SEAS FORECAST ISSUED BY THE

..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH ENTERS THE ATLANTIC NEAR 11N15W TO 04N19W. THE
ITCZ CONTINUES FROM THAT POINT TO 03S42W. SCATTERED MODERATE
CONVECTION IS NOTED ALONG AND WITHIN 270 NM ON EITHER SIDE OF THE
ITCZ.
..GULF OF AMERICA
A STATIONARY FRONT EXTENDS SOUTHWESTWARD FROM CAPE SABLE IN
SOUTHWEST FLORIDA TO BEYOND CANCUN, MEXICO. GENTLE TO MODERATE NE
TO SE WINDS AND SEAS OF 3 TO 5 FT ARE PRESENT NEAR THE AFOREMENTIONED
FRONT, AND ALONG THE MEXICO AND TEXAS COASTLINE. SURFACE RIDGING
PREVAILS ACROSS THE BASIN IN THE WAKE OF THE FRONT, ANCHORED BY A
HIGH PRESSURE CENTERED N OF THE AREA WITH SLIGHT TO MODERATE SEAS.
FOR THE FORECAST, THE FRONT WILL LIFT BACK TO THE N TODAY AS HIGH
PRESSURE OVER THE REGION BEGINS TO SHIFT EASTWARD. A STRONG COLD
FRONT IS EXPECTED TO MOVE INTO THE NW GULF SUN NIGHT, QUICKLY
REACHING THE SOUTHEASTERN GULF BY MON NIGHT AND SLOW DOWN AS IT
MOVES INTO THE NORTHWESTERN CARIBBEAN BY LATE TUE. STRONG TO NEAR
GALE-FORCE N WINDS WILL FOLLOW THE FRONT ALONG WITH SEAS RAPIDLY
BECOMING ROUGH. GALE-FORCE WINDS WILL BE POSSIBLE IN THE NW GULF,

THE WINDS OFFSHORE VERACRUZ MAY ATTAIN BRIEF GUSTS TO STORM-FORCE.
IN THE WAKE OF THE FRONT, HIGH PRESSURE WILL BUILD ACROSS THE
REGION INTO MIDWEEK.
..CARIBBEAN SEA
THE PRESSURE GRADIENT BETWEEN NORTH-CENTRAL ATLANTIC HIGH
PRESSURE AND LOWER PRESSURE IN COLOMBIA IS SUPPORTING PULSING
FRESH TO STRONG TRADES ACROSS THE SOUTH-CENTRAL BASIN. ROUGH SEAS
ARE EXPECTED WITH THESE WINDS. FRESH E TRADE WINDS AND MODERATE
SEAS PREVAIL ELSEWHERE E OF 83W, WHILE MODERATE E WINDS AND SLIGHT

FOR THE FORECAST, PULSING FRESH TO STRONG TRADES WILL PREVAIL ACROSS
THE SOUTH-CENTRAL BASIN THROUGH THE MORNING HOURS. THE HIGH
PRESSURE WILL SHIFT EASTWARD TODAY, WITH A BRIEF WEAKENING OF THE
GRADIENT ALLOWING FOR FRESH TO STRONG TRADES TO BE CONFINED TO
SOUTH OF 13N BETWEEN 72W AND 76W. AFTERWARD, NEW HIGH PRESSURE
WILL BUILD WESTWARD ACROSS THE CENTRAL ATLANTIC NEXT WEEK, WITH
THE RESULTING PRESSURE GRADIENT LEADING TO FRESH TO STRONG TRADES
AND BUILDING SEAS EXTENDING FROM THE TROPICAL NORTH ATLANTIC TO
THE EASTERN AND CENTRAL CARIBBEAN, INCLUDING THROUGH PASSAGES.
..ATLANTIC OCEAN
A STATIONARY FRONT MEANDERS SOUTHWESTWARD FROM NEAR BERMUDA ACROSS
31N69W AND THE NORTHWEST BAHAMAS TO BEYOND THE SOUTHERN TIP OF
FLORIDA. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE
OCCURRING NEAR AND UP TO 50 NM ON EITHER SIDE OF THE FRONT. FARTHER
EAST, A SURFACE TROUGH EMBEDDED WITHIN THE TRADE WINDS IS CAUSING
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS EAST OF THE WINDWARD
ISLANDS FROM 10N TO 16N BETWEEN 51W AND 54W.
GENTLE WITH MODERATE NE TO SE WINDS AND SEAS OF 4 TO 6 FT ARE
EVIDENT NORTH OF 23N BETWEEN 55W AND THE FLORIDA/SOUTHERN GEORGIA

FOR THE FORECAST WEST OF 55W, A HIGH PRESSURE WILL BUILD WEST-
SOUTHWESTWARD TOWARD THE BAHAMAS THROUGH THE WEEKEND BEFORE IT
WILL RETREAT EASTWARD EARLY NEXT WEEK IN RESPONSE TO THE NEXT COLD
FRONT. THE FRONT WILL MOVE OFF THE U.S. SOUTHEASTERN COAST MON
EVENING, THEN SLOW DOWN AND STALL FROM NEAR 31N72W TO THE CENTRAL
BAHAMAS AND TO CENTRAL CUBA BY LATE TUE. FRESH TO STRONG SOUTHERLY
WINDS AND ROUGH SEAS WILL DEVELOP OVER THE NW FORECAST WATERS
STARTING SUN AFTERNOON AHEAD OF THE FRONT. FRESH TO STRONG
NORTHWEST WINDS WILL FOLLOW THE FRONT THROUGH TUE. TO THE SOUTH,
ROUGH SEAS PRODUCED BY LONG-PERIOD E SWELL WILL IMPACT THE WATERS
