NWS NATIONAL HURRICANE CENTER MIAMI, FL
334 PM EST FRI DEC 13 2024
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
STRONG RIDGING OVER THE SE UNITED STATES WILL
CONTINUE TO FORCE FRESH TO STRONG NE WINDS ACROSS THE CENTRAL
AND W CARIBBEAN INCLUDING THROUGH THE WINDWARD PASSAGE UNTIL SUN
NIGHT. A BROAD SURFACE TROUGH EXTENDING ACROSS THE LESSER
ANTILLES THIS AFTERNOON WILL GRADUALLY MOVE WESTWARD OVER THE
NEXT FEW DAYS. THIS TROUGH WILL CAUSE THE PRESSURE GRADIENT TO
RELAX ACROSS MOST OF THE CARIBBEAN AND EARLY NEXT WEEK THE
TRADES ACROSS THE CARIBBEAN SHOULD BE ONLY MODERATE OR WEAKER.
LOOKING AHEAD, A BUILDING RIDGE MAY ENHANCE THE TRADES OVER THE
CENTRAL CARIBBEAN STARTING ON TUE NIGHT.

SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A STATIONARY FRONT THAT EXTENDS FROM JUST WEST OF
BERMUDA TO CENTRAL CUBA SHOULD DISSIPATE BY TONIGHT. A 1008 MB
LOW NEAR 23N62W SITS ALONG A NORTH-SOUTH ORIENTED TROUGH. AS THE
LOW/TROUGH SHIFTS WESTWARD, A LARGE AREA OF STRONG TO NEAR GALE
NE WINDS AND VERY ROUGH SEAS WILL SET UP OVER ALL OF THE WATERS
WEST OF 65W DURING THE WEEKEND. AS THE PRESSURE GRADIENT
TIGHTENS BETWEEN THE LOW/TROUGH AND HIGH PRESSURE OVER THE US
MID-ATLANTIC WATERS, PEAK WINDS SHOULD REACH GALE FORCE SAT AND
SAT NIGHT BETWEEN THE WATERS OF THE BAHAMAS AND BERMUDA. DURING
SUN AND MON, CONDITIONS WILL GRADUALLY IMPROVE, AND BY TUE AND
WED WINDS WILL BE REDUCED MODERATE TO FRESH ACROSS THE ENTIRE
AREA.
