MARINE WEATHER HF VOICE BROADCAST  
NWS NATIONAL HURRICANE CENTER MIAMI, FL  
313 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  
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.
