NWS NATIONAL HURRICANE CENTER MIAMI, FL
215 PM EST WED DEC 3 2025
MARINE WEATHER HF VOICE BROADCAST FOR THE TROPICAL N ATLANTIC
FROM 07N TO 19N W OF 55W, THE N ATLANTIC FROM 19N TO
31N W OF 55W INCLUDING THE BAHAMAS, AND THE CARIBBEAN SEA.
SEAS GIVEN AS SIGNIFICANT WAVE HEIGHT, WHICH IS THE AVERAGE
HEIGHT OF THE HIGHEST 1/3 OF THE WAVES. INDIVIDUAL WAVES MAY BE
MORE THAN TWICE THE SIGNIFICANT WAVE HEIGHT.
SYNOPSIS FOR CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM
07N TO 19N W OF 55W
SYNOPSIS
BUILDING HIGH PRESSURE NORTH OF THE CARIBBEAN SEA
WILL SUPPORT MODERATE TO FRESH EASTERLY WINDS OVER MUCH OF THE
BASIN STARTING THU AND CONTINUING INTO EARLY NEXT WEEK.
MEANWHILE, MODERATE TO LOCALLY ROUGH SEAS, IN NE SWELL, WILL
PERSIST ACROSS THE NE CARIBBEAN PASSAGES THROUGH THE WEEK AND
INTO THE WEEKEND. A SURFACE TROUGH, CURRENTLY LOCATED NEAR 64W,
WILL CONTINUE TO MOVE WESTWARD ACROSS THE EASTERN CARIBBEAN
THROUGH TONIGHT BEFORE DISSIPATING. FRESH TO STRONG WINDS AND
LOCALLY ROUGH SEAS ARE NOTED IN THE WAKE OF THIS TROUGH. THE
ASSOCIATED MOISTURE IS PRODUCING SOME SHOWER ACTIVITY AND
ISOLATED THUNDERSTORMS ACROSS MUCH OF THE LESSER ANTILLES.
LOOKING AHEAD, A COLD FRONT MAY APPROACH THE NW CARIBBEAN EARLY
NEXT WEEK.
