SYNOPSIS
HURRICANE ERIN IS NEAR 24.8N 72.0W AT 5 AM EDT, AND
IS MOVING NORTHWEST AT 6 KT. MAXIMUM SUSTAINED WINDS ARE 100 KT
WITH GUSTS TO 120 KT, AND THE MINIMUM CENTRAL PRESSURE IS
955 MB. ERIN WILL MOVE TO 26.1N 72.7W THIS AFTERNOON, 28.1N 73.5W
WED MORNING, 30.3N 74.0W WED AFTERNOON, 32.6N 73.4W THU MORNING,
34.6N 71.4W THU AFTERNOON, AND 36.5N 68.4W FRI MORNING. ERIN WILL
CHANGE LITTLE IN INTENSITY AS IT MOVES NEAR 39.5N 61.0W EARLY SAT.
SWELLS GENERATED BY ERIN WILL AFFECT THE BAHAMAS, BERMUDA, THE
EAST COAST OF THE UNITED STATES, AND ATLANTIC CANADA DURING THE
NEXT SEVERAL DAYS. THESE ROUGH OCEAN CONDITIONS ARE EXPECTED TO
CAUSE LIFE-THREATENING SURF AND RIP CURRENTS. OTHERWISE, A TROPICAL
WAVE LOCATED OVER THE CENTRAL TROPICAL ATLANTIC CONTINUES TO
PRODUCE A BROAD AREA OF DISORGANIZED SHOWERS AND THUNDERSTORMS.
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR GRADUAL DEVELOPMENT
OF THIS SYSTEM, AND A TROPICAL DEPRESSION COULD FORM TOWARD THE

WEST-NORTHWESTWARD AT ABOUT 20 KT ACROSS THE CENTRAL TROPICAL
ATLANTIC AND APPROACH THE VICINITY OF THE LEEWARD ISLANDS ON
FRIDAY.
