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 SAT  
NIGHT. A BROAD SURFACE TROUGH EXTENDING ACROSS THE LESSER  
ANTILLES THIS MORNING WILL GRADUALLY MOVE WESTWARD OVER THE NEXT  
FEW DAYS. THIS TROUGH WILL CAUSE THE PRESSURE GRADIENT TO RELAX  
ACROSS MOST OF THE CARIBBEAN ON SUN. LOOKING AHEAD ON MON AND  
TUE, TRADES ACROSS THE CARIBBEAN SHOULD BE MODERATE OR WEAKER.

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 1012 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 NORTH OF THE BAHAMAS AND BERMUDA.  
DURING SUN AND MON, CONDITIONS WILL GRADUALLY IMPROVE, AND BY  
TUE WINDS WILL BE REDUCED TO FRESH ACROSS THE AREA.
