..SPECIAL FEATURES
METEO-FRANCE GALE WARNING: METEO-FRANCE FORECASTS GALE-FORCE N TO
NE WINDS OFFSHORE AGADIR NOW THROUGH 17/00 UTC. ROUGH TO VERY
ROUGH SEAS WILL LIKELY ACCOMPANY THESE WINDS. FOR MORE DETAILS,
REFER TO THE METEO-FRANCE HIGH SEAS FORECAST LISTED ON THEIR
WEBSITE HTTPS://WWWMIWS.WMO.INT.
..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH ENTERS THE ATLANTIC NEAR 11N15W AND EXTENDS TO
04N19W. THE ITCZ CONTINUES FROM 04N19W TO 01S46W. SCATTERED
MODERATE CONVECTION IS OCCURRING SOUTH OF 05N AND EAST OF 20W,
AND S OF 04N BETWEEN 32W AND 45W.
GULF OF AMERICA...
A COLD FRONT EXTENDS FROM 27N82W TO 28N92W. RECENT BUOY AND
SCATTEROMETER DATA SHOW MODERATE TO LOCALLY FRESH N TO NE WINDS
NORTH OF THE FRONT IN THE NORTHEASTERN GULF OF AMERICA. OTHERWISE,
MODERATE E TO SE WINDS PREVAIL ACROSS MUCH OF THE GULF AWAY FROM
THE FRONT, ALONG WITH SLIGHT SEAS ACROSS THE BASIN.
FOR THE FORECAST, MODERATE TO LOCALLY FRESH NORTH TO NORTHEAST
WINDS WILL OCCUR ACROSS THE NORTHEASTERN GULF OF AMERICA THIS
MORNING AS A COLD FRONT MOVES SOUTHWARD. ELSEWHERE, PULSING FRESH
TO STRONG NORTHEAST WINDS ARE EXPECTED EACH AFTERNOON AND NIGHT
OFFSHORE OF THE YUCATAN PENINSULA AND INTO THE EASTERN BAY OF
CAMPECHE AS A TROUGH DEVELOPS EACH DAY AND MIGRATES WESTWARD.
OTHERWISE, MODERATE TO FRESH SOUTHEAST WINDS WILL DEVELOP BY EARLY
THU WEST OF 90W AS LOW PRESSURE DEEPENS IN THE PLAINS. FRESH TO
LOCALLY STRONG SOUTHEAST WINDS WILL EXPAND IN COVERAGE BY FRI
ACROSS MUCH OF THE BASIN, INCLUDING THROUGH THE STRAITS OF FLORIDA
AND YUCATAN CHANNEL, AND WINDS WILL PULSE THROUGH EARLY SUN.
LOCALLY ROUGH SEAS WILL ACCOMPANY THESE WINDS.
CARIBBEAN SEA...
A SURFACE TROUGH HAS BEEN ANALYZED FROM NORTHERN HAITI
SOUTHWESTWARD THROUGH THE GULF OF HONDURAS. SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS ARE OCCURRING S OF 18N AND W OF 83W TO THE
COASTS OF HONDURAS, GUATEMALA, AND BELIZE. ELSEWHERE, A 1008 MB
LOW OVER NORTHWESTERN COLOMBIA IS SUPPORTING FRESH TO STRONG NE
WINDS OFFSHORE OF COLOMBIA AND IN THE GULF OF VENEZUELA. SEAS IN
THIS AREA ARE ANALYZED AT 7-9 FT. OTHERWISE, MODERATE TO FRESH
TRADE WINDS AND MODERATE SEAS PREVAIL IN THE REMAINDER OF THE
CENTRAL AND EASTERN CARIBBEAN, WITH GENTLE TO LOCALLY MODERATE
WINDS AND SLIGHT SEAS IN THE NORTHWESTERN BASIN.
FOR THE FORECAST, STRONG TO NEAR-GALE FORCE NORTHEAST WINDS AND
ROUGH SEAS ARE EXPECTED OFFSHORE OF COLOMBIA EACH NIGHT AND
MORNING THROUGH THIS WEEKEND. IN THE GULF OF VENEZUELA, PULSING
STRONG WINDS WILL OCCUR THROUGH THIS WEEKEND. OTHERWISE, MODERATE
TO FRESH TRADE WINDS AND MODERATE SEAS WILL PREVAIL OVER THE BASIN
THROUGH THU. LOOKING AHEAD, FRESH TO LOCALLY STRONG NORTHEAST
WINDS ARE EXPECTED TO DEVELOP THU NIGHT INTO FRI OVER THE
NORTHWESTERN AND CENTRAL PORTIONS OF THE SEA, INCLUDING IN THE
WINDWARD PASSAGE, AS A TIGHTENING PRESSURE GRADIENT DEVELOPS
BETWEEN THE COLOMBIAN LOW AND INTENSIFYING WESTERN ATLANTIC HIGH
PRESSURE. WIDESPREAD FRESH TO STRONG WINDS AND LOCALLY ROUGH SEAS
ARE ANTICIPATED FRI NIGHT INTO EARLY NEXT WEEK.
ATLANTIC OCEAN...
PLEASE REFER TO THE SPECIAL FEATURES SECTION FOR DETAILS ON GALE-
FORCE WINDS OFFSHORE OF AGADIR AND ROUGH TO VERY ROUGH SEAS NEAR
THE CANARY ISLANDS.
A STATIONARY FRONT HAS BEEN ANALYZED FROM 31N47W SOUTHWESTWARD TO
NORTHERN HISPANIOLA. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
ARE OBSERVED BETWEEN THE FRONT AND 28N BETWEEN 57W AND 72W.
PREVAILING NW SWELL BEHIND THIS FRONT IS PRODUCING ROUGH SEAS OF 8
TO 10 FT NORTH OF 28N AND EAST OF 52W. FARTHER WEST, A COLD FRONT
EXTENDS FROM 31N72W INTO SE FLORIDA. SCATTERED SHOWERS ARE
OCCURRING ALONG THE FRONT. RECENT SCATTEROMETER DATA INDICATE
MODERATE TO FRESH SW WINDS AHEAD OF THE FRONT OUT TO ABOUT 70W AND
N OF 27N ALONG WITH MODERATE SEAS. BEHIND THE FRONT, MODERATE TO
FRESH N TO NE WINDS AND MODERATE SEAS ARE OBSERVED.
THE REMAINDER OF THE TROPICAL AND SUBTROPICAL ATLANTIC IS
DOMINATED BY A 1027 HIGH PRESSURE SYSTEM CENTERED NEAR 33N21W.
THE PRESSURE GRADIENT BETWEEN THIS RIDGE AND LOWER PRESSURES IN
THE TROPICS SUPPORT MODERATE TO LOCALLY FRESH NE TO E WINDS AND
MODERATE SEAS ACROSS THE VAST MAJORITY OF THE BASIN, ESPECIALLY
WEST OF 30W. FRESH TO STRONG NE WINDS AND SEAS OF 5-8 FT ARE FOUND
N OF 15N AND E OF 30W. ANOTHER CORRIDOR OF FRESH TO LOCALLY
STRONG NE WINDS IS OBSERVED FROM 03N TO 14N BETWEEN 30W AND 55W,
WITH SEAS OF 6-9 FT IN THESE WATERS. ELSEWHERE, MODERATE OR
WEAKER WINDS MODERATE SEAS PREVAIL.

31N61W TO THE CENTRAL BAHAMAS BY THU EVENING. THE FRONT WILL THEN
BECOME STATIONARY OVER THE EASTERN PART OF THE AREA DURING THE
UPCOMING WEEKEND AS A LARGE AREA OF HIGH PRESSURE BUILDS IN BEHIND
IT, WITH THE PARENT HIGH CENTER TO BE LOCATED NEAR 31N72W. A
TIGHTENING PRESSURE GRADIENT BETWEEN THE HIGH PRESSURE AND THE
FRONT IS EXPECTED TO DEVELOP FRESH TO STRONG NORTHEAST TO EAST
WINDS BEHIND THE FRONT SOUTH OF ABOUT 26N STARTING FRI. THESE
WINDS WILL EXPAND IN COVERAGE GOING INTO THE WEEKEND. SEAS EAST
AND NORTHEAST OF THE BAHAMAS WILL BECOME ROUGH BEGINNING FRI
