SYNOPSIS
A STRONG PRESSURE GRADIENT WILL CONTINUE TO FORCE
FRESH TO STRONG NE WINDS OVER THE NW CARIBBEAN UNTIL MON MORNING
AND THROUGH THIS AFTERNOON IN THE WINDWARD PASSAGE. A BROAD
SURFACE TROUGH OVER THE SW N ATLANTIC WATERS EXTENDING INTO THE
CARIBBEAN THROUGH HISPANIOLA WILL DRIFT WESTWARD ACROSS THE

CENTRAL BASIN THROUGH MON. LOOKING AHEAD, A BUILDING RIDGE N OF
THE AREA WILL ENHANCE THE TRADE WIND FLOW OVER THE CENTRAL
CARIBBEAN TO FRESH TO STRONG SPEEDS TUE NIGHT THROUGH THU.
