NWS NATIONAL HURRICANE CENTER MIAMI, FL
1017 PM 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
A STRONG PRESSURE GRADIENT WILL CONTINUE TO FORCE
FRESH TO STRONG NE WINDS OVER THE NW CARIBBEAN AND THROUGH THE
WINDWARD PASSAGE UNTIL EARLY SUN. A BROAD SURFACE TROUGH OVER
THE SW N ATLANTIC WATERS EXTENDING INTO THE CARIBBEAN THROUGH
DOMINICAN REPUBLIC WILL DRIFT WESTWARD ACROSS THE CENTRAL
CARIBBEAN ON SUN WHILE WEAKENING. 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 N OF THE AREA MAY ENHANCE
THE TRADE WIND FLOW OVER THE CENTRAL CARIBBEAN TO FRESH TO
STRONG SPEEDS TUE NIGHT THROUGH WED NIGHT.
