SYNOPSIS
A GALE WARNING IS IN EFFECT ACROSS THE NE WATERS
ASSOCIATED WITH POST-TROPICAL CYCLONE IMELDA THAT WILL CONTINUE
TO MOVE AWAY FROM THE FORECAST REGION. WINDS ARE FORECAST TO
DIMINISH BELOW GALE FORCE BY TONIGHT. A BUILDING RIDGE OVER THE
WESTERN ATLANTIC COMBINED WITH A FRONTAL BOUNDARY EXTENDING
ROUGHLY ALONG 24N/25N WILL SUPPORT FRESH TO STRONG WINDS ACROSS
MOST OF THE AREA LIKELY THROUGH SUN. LONG PERIOD NORTHERLY
SWELL GENERATED BY POST-TROPICAL CYCLONE IMELDA WILL CONTINUE
TO AFFECT JUST ABOUT THE ENTIRE FORECAST DOMAIN THROUGH EARLY
NEXT WEEK. MEANWHILE, AN AREA OF LOW PRESSURE MAY MAY FORM
ALONG THE FRONTAL BOUNDARY NEAR THE NORTHWESTERN BAHAMAS AND
SOUTHERN FLORIDA DURING THE NEXT DAY OR TWO. ANY ADDITIONAL
DEVELOPMENT IS EXPECTED TO BE SLOW TO OCCUR AS THE SYSTEM MOVES
NORTHWESTWARD ACROSS THE FLORIDA PENINSULA AND INTO THE GULF OF
AMERICA.
