LIKELY BE WIDESPREAD INUNDATION OF COASTAL ROADS AND BASEMENTS
WITH LIFE THREATENING INUNDATION DEPTHS ABOVE 3 FEET POSSIBLE
IN SOME LOCATIONS...ESPECIALLY WHERE WAVE OVERWASH IS
INVOLVED. MANY NEIGHBORHOODS MAY BE AT RISK OF BEING CUT OFF
FOR AN EXTENDED TIME. THIS IS A POTENTIALLY VERY DANGEROUS
EVENT...AND EVACUATION OF SOME NEIGHBORHOODS MAY BE NECESSARY.
IN ADDITION...SEVERE EROSION IS LIKELY AND MAY COMPROMISE
PROTECTIVE DUNES...SEA WALLS AND OTHER STRUCTURES.
&&
TIME OF HIGH TOTAL TIDES ARE APPROXIMATE TO THE NEAREST HOUR.
