AS THE NIGHT WENT BY...SHOWERS WERE ON THE INCREASE ACROSS THE LOCAL AREA...BUT PARTICULARLY OVER THE COASTAL WATERS. ALL THIS WEATHER CAN BE ATTRIBUTED TO A BROAD TROPICAL WAVE MOVING WESTWARD ACROSS THE EASTERN CARIBBEAN. BASED ON SATELLITE PICTURES AND LATEST QUICKSCAT PASS...THE WAVE AXIS IS NEAR 64 WEST EARLY THIS MORNING.
