WITHIN 200 NM EAST OF THE COAST OF FLORIDA
SYNOPSIS
LARGE NORTHERLY SWELL GENERATED BY EXTRATROPICAL
CYCLONE ERIN WILL CONTINUE TO AFFECT THE W ATLANTIC WATERS
THROUGH THE NEXT FEW DAYS. IN THE WAKE OF ERIN, CENTRAL ATLANTIC
HIGH PRESSURE WILL BUILD W-SW TOWARD THE CENTRAL BAHAMAS AND THE
STRAITS OF FLORIDA. MEANWHILE, SHOWERS AND THUNDERSTORMS HAVE
BECOME A LITTLE BETTER ORGANIZED IN ASSOCIATION WITH A TROUGH OF
LOW PRESSURE, AL90, LOCATED A FEW HUNDRED NAUTICAL MILES NORTH OF
THE NORTHERN LEEWARD ISLANDS. ENVIRONMENTAL CONDITIONS APPEAR
CONDUCIVE FOR FURTHER DEVELOPMENT OF THIS SYSTEM, AND A TROPICAL
STORM IS EXPECTED TO FORM THIS WEEKEND WHILE IT MOVES NORTH-
NORTHWESTWARD AND THEN NORTHWARD OVER THE SOUTHWESTERN ATLANTIC.
THIS SYSTEM HAS A HIGH CHANCE OF TROPICAL CYCLONE FORMATION.
REGARDLESS OF FORMATION, GALE-FORCE WINDS ARE EXPECTED TO DEVELOP
ACROSS THE EASTERN SEMICIRCLE OF THIS LOW BEGINNING LATE TONIGHT
INTO SUN MORNING, WITH BUILDING SEAS. A SLOW MOVING COLD FRONT MAY
MOVE OFF THE SE U.S. INTO THE NW WATERS BY THE MIDDLE OF NEXT
WEEK.
