346 PM EST SUN DEC 7 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
WEAK HIGH PRESSURE N OF THE BASIN ALONG ABOUT 25N
WILL SUPPORT MODERATE TO FRESH EASTERLY TRADE WINDS AND MODERATE
SEAS OVER THE CENTRAL AND EASTERN CARIBBEAN THROUGH AT LEAST THE
MIDDLE OF NEXT WEEK. MODERATE OR LIGHTER WINDS AND SLIGHT TO
MODERATE SEAS WILL PREVAIL ELSEWHERE. FRESH TO LOCALLY STRONG
TRADE WINDS AND PERSISTENT E-NE SWELL WILL SUPPORT ROUGH SEAS
ACROSS THE ATLANTIC WATERS AND PASSAGES OF THE LESSER ANTILLES
THROUGH NEXT FRI. LOOKING AHEAD, A WEAKENING COLD FRONT WILL
APPROACH THE NORTHWESTERN CARIBBEAN ON TUE AND LINGER ACROSS THE
YUCATAN CHANNEL AND STRAITS OF FLORIDA THROUGH WED NIGHT BEFORE
DISSIPATING. HIGH PRESSURE WILL BUILD ACROSS THE EASTERN GULF OF
AMERICA BY THE MIDDLE OF NEXT WEEK, LEADING TO STRONG WINDS AND
ROUGH SEAS IN THE SOUTH-CENTRAL CARIBBEAN INTO LATE NEXT WEEK.
