A rapidly deepening low pressure system tracking up the eastern seaboard on Tuesday March 14th brought gale to storm force winds to the area waters, resulting in 2 to 4 feet of surge during the Tuesday morning high tidal cycle. This resulted in widespread minor to moderate coastal impacts to the region. Erosion impacts to the beachfront were mainly minor.
