NWS NATIONAL HURRICANE CENTER MIAMI, FL  
1013 PM EST TUE NOV 12 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.
 
SHOWERS AND THUNDERSTORMS OVER THE CENTRAL  
CARIBBEAN SEA HAVE BECOME MORE ORGANIZED IN ASSOCIATED WITH A  
BROAD AREA OF LOW PRESSURE AND A TROPICAL WAVE MOVING ACROSS  
JAMAICA TONIGHT. ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR  
DEVELOPMENT, AND A TROPICAL DEPRESSION IS LIKELY TO FORM WITHIN  
THE NEXT COUPLE OF DAYS WHILE THE SYSTEM MOVES SLOWLY WESTWARD  
INTO THE WESTERN CARIBBEAN SEA. AFTERWARD, FURTHER DEVELOPMENT  
IS HIGHLY LIKELY WHILE THE DISTURBANCE MEANDERS OVER THE WESTERN  
CARIBBEAN SEA THROUGH THE WEEKEND. THE SYSTEM IS FORECAST BEGIN  
MOVING SLOWLY NW BY EARLY NEXT WEEK. REGARDLESS OF DEVELOPMENT,  
STRONG TO NEAR GALE FORCE WINDS, ROUGH SEAS AND HEAVY RAINS ARE  
EXPECTED OVER THE NW AND PORTIONS OF THE SW CARIBBEAN THROUGH  
EARLY NEXT WEEK. OTHERWISE, GENTLE TO MODERATE WINDS AND SLIGHT  
TO MODERATE SEAS WILL DOMINATE THE CENTRAL AND EASTERN CARIBBEAN  
THROUGH THE FORECAST PERIOD.
