The combination of strong high pressure over Southeast Canada and intensifying low pressure tracking slowly northeast from the Mid-Atlantic States created a prolonged period of strong east winds across the region March 12th through the 14th. The highest winds and resultant tidal rises occurred on March 13th with widespread moderate coastal flooding occurring.  Positive tidal departures of 3 to 5 feet were recorded, with many places seeing water levels reaching their highest levels in almost 20 years.  In addition, the prolonged east winds generated high surf that battered the Atlantic facing shoreline for several days, which caused severe beach erosion.

This will require 200,000 cubic feet of sand to be placed on the shore in April at an estimated cost of 1 million dollars.
