..MONSOON TROUGH/ITCZ
THE MONSOON TROUGH ENTERS THE EAST ATLANTIC NEAR 07N12W TO
04N18W. THE ITCZ CONTINUES FROM THAT POINT TO 04S39W. SCATTERED
MODERATE TO ISOLATED STRONG CONVECTION IS NOTED S OF 04N AND E OF
29W.
GULF OF AMERICA...
SURFACE RIDGING PREVAILS ACROSS THE BASIN, AND PROVIDES FOR
MODERATE TO FRESH SE TO S WINDS ACROSS THE BASIN. SEAS ARE 6 TO 8
FT ACROSS THE NORTHERN HALF OF THE GULF, AND 4 TO 6 FT ELSEWHERE.
FOR THE FORECAST, MODERATE TO FRESH SOUTHERLY RETURN FLOW ACROSS
THE WEST AND CENTRAL PORTIONS OF THE GULF WILL GRADUALLY DIMINISH
TONIGHT AHEAD OF THE NEXT COLD FRONT FORECAST TO ENTER THE NW
GULF EARLY FRI. THIS FRONT IS EXPECTED TO SINK SLOWLY SOUTHWARD
ACROSS THE NORTH HALF OF THE GULF FRI THROUGH SAT NIGHT AND
GRADUALLY DISSIPATE. HIGH PRESSURE N OF THE GULF WILL BUILD BACK
ACROSS THE BASIN SUN INTO EARLY NEXT WEEK.
CARIBBEAN SEA...
HIGH PRESSURE N OF THE AREA COMBINED WITH THE COLOMBIAN LOW
SUPPORTS FRESH TO STRONG TRADE WINDS OVER THE CENTRAL CARIBBEAN,
WITH THE STRONGEST WINDS OFFSHORE COLOMBIA. SEAS ARE 8 TO 9 FT
WITH THE STRONGEST WINDS. MODERATE TO FRESH TRADES AND MODERATE
SEAS DOMINATE THE EASTERN CARIBBEAN WHILE MAINLY MODERATE SE WINDS
WITH MODERATE SEAS ARE NOTED OVER THE NW PART OF THE BASIN. SEAS
ARE LOCALLY HIGHER, TO 8 FT, WITHIN ATLANTIC PASSAGE BETWEEN THE
LESSER ANTILLES AND THE MONA PASSAGE, DUE TO LONG PERIOD NORTHERLY
SWELL FROM THE ATLANTIC.
FOR THE FORECAST, THE BROAD RIDGE OVER THE CENTRAL ATLANTIC WILL
CONTINUE TO EXTEND INTO THE CARIBBEAN SEA THROUGH THE FORECAST
PERIOD, SUPPORTING FRESH TO STRONG EASTERLY TRADE WINDS AND
MODERATE TO ROUGH SEAS ACROSS THE CENTRAL AND EASTERN CARIBBEAN.
ROUGH SEAS IN MIXED SWELL WILL PREVAIL IN THE TROPICAL N ATLANTIC

EVENT CONTINUES TO AFFECT THE WATERS OVER THE CENTRAL AND
EASTERN ATLANTIC. PLEASE, SEE THE SPECIAL FEATURES SECTION ABOVE FOR
MORE INFORMATION.
HIGH PRESSURE DOMINATES THE ENTIRE ATLANTIC FORECAST WATERS WITH
A 1035 MB CENTER LOCATED W OF THE AZORES. UNDER THE INFLUENCE OF
THIS SYSTEM, FRESH TO STRONG NE TO E WINDS ARE NOTED ACROSS MOST
THE WATERS E OF 55W WITH MODERATE TO FRESH WINDS W OF 55W. A
SURFACE TROUGH IS ANALYZED FROM 30N64W TO 24N66W. SEAS OF 8 TO 12
FT IN NW SWELL DOMINATE THE WATERS E OF A LINE FROM 31N44W TO
20N67W. SEAS OF 4 TO 7 FT ARE NOTED ELSEWHERE.
FOR THE FORECAST WEST OF 55W, THE SURFACE RIDGE WILL CONTINUE TO
DOMINATE THE FORECAST WATERS. ROUGH SEAS PREVAIL OVER THE SE
WATERS. AREAL COVERAGE OF THESE ROUGH SEAS WILL GRADUALLY DECREASE
THROUGH THU NIGHT, WITH A SMALLER AREA OF ROUGH SEAS CONTINUING
OVER PORTIONS OF THE SE WATERS THROUGH THE END OF THE PERIOD. A
WEAK FRONT WILL SHIFT OFF THE SE U.S. COAST EARLY SAT AND MOVE
SLOWLY SOUTHEASTWARD AND WEAKEN ACROSS THE WATERS W OF 65W THROUGH
SUN NIGHT BEFORE DISSIPATING.
