SYNOPSIS
A STRONG PRESSURE GRADIENT WILL CONTINUE TO FORCE
FRESH TO STRONG NE WINDS IN THE LEE OF CUBA, AND OVER THE NW
CARIBBEAN THROUGH MON MORNING. A BROAD SURFACE TROUGH OVER THE
SW N ATLANTIC WATERS EXTENDING INTO THE CARIBBEAN THROUGH
HISPANIOLA WILL DRIFT WESTWARD ACROSS THE CENTRAL CARIBBEAN
TODAY WHILE WEAKENING. THIS TROUGH WILL CAUSE THE PRESSURE
GRADIENT TO RELAX ACROSS MOST OF THE CARIBBEAN, ALLOWING FOR
GENTLE TO MODERATE TRADES ACROSS EASTERN AND 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.
