SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS  
   
SYNOPSIS
 
A STATIONARY FRONT EXTENDING FROM NEAR BERMUDA TO  
1012 MB LOW PRESSURE NEAR 30N72W TO NEAR CAPE CANAVERAL, FLORIDA  
WILL LINGER THROUGH EARLY MORNING WITH FRESH TO LOCALLY STRONG  
WINDS AND SEAS UP TO 8 FT NORTH OF IT. WIDELY SCATTERED SHOWERS  
AND ISOLATED THUNDERSTORMS WILL PREVAIL ACROSS MUCH OF THE  
WATERS NORTH OF 25N THROUGH AT LEAST TODAY. THE FRONT WILL  
RETREAT NORTHWARD AS A WARM AND STALL ALONG 31N THROUGH THE END  
OF THE WEEK. IN A FEW DAYS, A NON-TROPICAL AREA OF LOW PRESSURE  
COULD FORM ALONG THE RESIDUAL FRONTAL BOUNDARY. THEREAFTER, SOME  
SUBTROPICAL OR TROPICAL DEVELOPMENT IS POSSIBLE DURING THE EARLY  
PART OF NEXT WEEK WHILE THE SYSTEM DRIFTS TO THE NORTH OR  
NORTHWEST. REGARDLESS OF DEVELOPMENT, INCREASING WINDS AND  
BUILDING SEAS WILL IMPACT THE WATERS NEAR 31N BY THE END OF THE  
WEEKEND INTO EARLY NEXT WEEK. GENTLE TO MODERATE WINDS AND SLIGHT  
TO MODERATE SEAS WILL PREVAIL OTHERWISE.
