..SPECIAL FEATURES
WESTERN ATLANTIC GALE WARNING: A STATIONARY FRONT EXTENDS FROM
31N72W SW TO A 1010 MB LOW NEAR 29N74W THEN TRANSITIONS TO A COLD
FRONT THAT MOVES ACROSS SE FLORIDA NEAR 25N80W. THE LOW PRESSURE
WILL TRACK SLOWLY NE, LIFTING N OF THE AREA NEAR BERMUDA THU,
WHILE THE FRONT DRIFTS E, EXTENDING SW FROM NEAR BERMUDA TO
WESTERN CUBA LATER THU INTO FRI. THUNDERSTORMS WITH GUSTY WINDS
WILL IMPACT WATERS ALONG AND EAST OF THE TRACK OF THE LOW
PRESSURE. THE PRESSURE GRADIENT BETWEEN STRONG HIGH PRESSURE TO
THE NORTH OF OUR WATERS AND THE FRONT IS SUPPORTING NE GALES
OFFSHORE NE FLORIDA. THESE GALES WILL SPREAD EASTWARD TO ABOUT
72W, MAINLY NORTH OF 28N, THROUGH WED NIGHT, BEFORE GRADUALLY
ENDING AS THE LOW PRESSURE MOVES NORTH OF THE AREA. VERY ROUGH
SEAS OF 15 TO 20 FT WILL BE GENERATED BY THESE GALES, AND ROUGH
SEAS IN N SWELL WILL IMPACT A MUCH LARGER AREA THROUGH THE END OF
THE WEEK. THE FRONT IS LIKELY TO LINGER OVER THE BASIN INTO THE
WEEKEND, SO MARINE CONDITIONS COULD BE SLOW TO IMPROVE.
EAST ATLANTIC LARGE SWELL: LONG PERIOD NW TO N SWELL BEHIND A
COLD FRONT THAT EXTENDS ACROSS NW AFRICA AND THE EASTERN ATLANTIC
IS CREATING SEAS OF 11 TO 13 FT NORTH OF 21N AND EAST OF 40W.
THIS SWELL EVENT WILL CONTINUE TO PROPAGATE SOUTHWARD WITH SEAS 8
FT OR GREATER REACHING AS FAR SOUTH AS 10N ON WED. BY LATE
THURSDAY AFTERNOON OR EARLY IN THE EVENING, THE SWELL SHOULD
DECAY ENOUGH TO ALLOW SEAS TO DROP BELOW 12 FT.
PLEASE READ THE LATEST HIGH SEAS FORECAST ISSUED BY THE NATIONAL
HURRICANE CENTER AT WEBSITE:
HTTPS://WWW.NHC.NOAA.GOV/TEXT/MIAHSFAT2.SHTML FOR MORE DETAILS.
GALE WARNING E OF 35W: METEO-FRANCE HAS ISSUED A GALE WARNING FOR
THE FORECAST ZONE OF MADEIRA. THE FORECAST CALLS FOR NW GALES TO
40 KT, WITH SEVERE GUSTS FROM 08/12 UTC TO 09/00 UTC AT LEAST.
VERY ROUGH SEAS IN NW SWELL ARE ALSO REACHING THE ISLANDS.
FOR MORE DETAILS, REFER TO THE METEO- FRANCE HIGH SEAS FORECAST
LISTED ON THEIR WEBSITE HTTPS://WWMIWS.WMO.INT
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH ENTERS THE ATLANTIC THROUGH THE COAST OF
LIBERIA, AFRICA AND CONTINUES SW TO 02N21W. THE ITCZ EXTENDS
WEST-SOUTHWESTWARD FROM 02N21W TO 00N35W TO NE BRAZIL NEAR
00N48W. SCATTERED MODERATE TO ISOLATED STRONG CONVECTION IS FROM
03S TO 07N BETWEEN 05W AND 38W.
..GULF OF AMERICA
THE TAIL OF A FRONT STALLS ACROSS SOUTHERN FLORIDA, ENTERING THE
GULF SE WATERS NEAR 25N81W AND CONTINUING TO A 1010 MB LOW NEAR
24N85W FROM WHERE A COLD FRONT STRETCHES SW THE NE YUCATAN
PENINSULA OFFSHORE WATERS NEAR 22N88W. SURFACE RIDGING HAS STARTED
TO BUILD ACROSS THE NORTHERN GULF, AND IS SUPPORTING FRESH TO NEAR
GALE FORCE NE WINDS ACROSS THE NE GULF OFFSHORES AS CONFIRMED BY
RECENT SCATTEROMETER DATA. SEAS WITH THESE WINDS ARE ROUGH TO 10
TO 11 FT. ELSEWHERE, WINDS ARE MODERATE OR WEAKER, AND SEAS
MODERATE IN THE 4 TO 7 FT RANGE.
FOR THE FORECAST, THE FRONT WILL STALL OVER THE FAR SE BASIN
THROUGH THU, AND STRONG TO NEAR GALE-FORCE NE WINDS AND ROUGH SEAS
WILL CONTINUE IN THE NE GULF DURING THIS TIME. CONDITIONS WILL
GRADUALLY IMPROVE FRI INTO THE WEEKEND AS THE HIGH PRESSURE BUILDS
SOUTHWESTWARD ACROSS THE NORTHERN BASIN.
..CARIBBEAN SEA
THE ATLANTIC RIDGE EXTENDS SW REACHING THE NE CARIBBEAN. THIS
SYSTEM IS SUPPORTING FRESH TO LOCALLY STRONG E TO SE WINDS AND
SEAS OF 5 TO 7 FT ACROSS THE EASTERN PART OF THE BASIN. GENTLE TO
MODERATE NE TO E WINDS AND 3 TO 5 FT SEAS ARE ONGOING ACROSS THE
SW CARIBBEAN WHILE LIGHT AND VARIABLE WINDS AND SLIGHT SEAS DOMINATE
THE NW CARIBBEAN. SCATTERED SHOWERS WITH EMBEDDED THUNDERSTORMS
ARE SEEN OVER HISPANIOLA AND E CUBA ADJACENT WATERS AS WELL AS IN
THE WINDWARD PASSAGE.
FOR THE FORECAST, FRESH TO STRONG TRADES WILL PREVAIL OVER THE
CENTRAL AND EASTERN BASIN INTO THU, WITH GENTLE TO MODERATE WINDS
TO THE WEST. STRONG HIGH PRESSURE WILL THEN BUILD SOUTHWARD FROM
THE WESTERN ATLANTIC, WITH A TIGHTENING PRESSURE GRADIENT LEADING
TO INCREASING WINDS, ESPECIALLY IN THE SOUTH-CENTRAL BASIN.
..ATLANTIC OCEAN
A GALE WARNING IS IN EFFECT FOR THE WESTERN ATLANTIC. PLEASE REFER
TO THE SPECIAL FEATURES SECTION FOR MORE DETAILS.
A STATIONARY FRONT EXTENDS FROM 31N72W SW TO A 1010 MB LOW NEAR
29N74W THEN TRANSITIONS TO A COLD FRONT THAT MOVES ACROSS SE
FLORIDA NEAR 25N80W. RECENT SCATTEROMETER DATA CONFIRM THE
PRESENCE OF GALES WEST OF THE LOW AND FRONT, OVER THE NE AND
CENTRAL FLORIDA OFFSHORE WATERS. SEAS WITH THESE WINDS ARE ROUGH
TO VERY ROUGH WITH PEAK SEAS OF 16 FT N OF THE BAHAMAS. ASIDE FROM
THE WINDS AND SEAS, HEAVY SHOWERS AND TSTMS CONTINUE TO AFFECT THE
OFFSHORE WATERS N OF 20N BETWEEN 62W AND 77W. OVER THE FAR E
ATLANTIC, THE TAIL OF A COLD FRONT STARTS TO WEAKEN NEAR 25N20W TO
23N41W. STRONG HIGH PRESSURE OF 1038 MB SW OF THE AZORES IS
DRIVING A LONG-PERIOD N TO NW SWELL THAT IS AFFECTING THE CENTRAL,
EASTERN AND TROPICAL ATLANTIC WATERS. SEE THE SPECIAL FEATURES
SWELL SECTION FOR FURTHER DETAILS. OTHERWISE, A BROAD SURFACE
RIDGE PREVAILS ELSEWHERE, SUPPORTING MODERATE TO FRESH E TO SE
WINDS AND MODERATE TO ROUGH SEAS.
FOR THE FORECAST WEST OF 55W, PLEASE REFER TO THE SPECIAL FEATURES
WESTERN ATLANTIC GALE WARNING SECTION FOR ALL THE INFORMATION
RELATED TO THE ABOVE MENTIONED FRONTAL BOUNDARY.
