MARINE WEATHER HF VOICE BROADCAST
NWS NATIONAL HURRICANE CENTER MIAMI, FL
420 AM EST SAT DEC 14 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
EARLY SUN. A BROAD SURFACE TROUGH OVER THE SW N ATLANTIC WATERS
EXTENDING INTO THE NE CARIBBEAN WILL GRADUALLY MOVE WESTWARD TO
THE SW CARIBBEAN THROUGH MON. THIS TROUGH WILL CAUSE THE
PRESSURE GRADIENT TO RELAX ACROSS MOST OF THE CARIBBEAN,
ALLOWING FOR GENTLE TO MODERATE TRADES ACROSS THE BASIN THROUGH
TUE. LOOKING AHEAD, A BUILDING RIDGE MAY ENHANCE THE TRADES OVER
THE CENTRAL CARIBBEAN TO FRESH TO STRONG SPEEDS TUE NIGHT
THROUGH WED NIGHT.
