 Tides of maximum height and depression produced during this period are known as spring tide.Spring tides that coincide with the moon's closest approach to Earth ("perigee") have been called perigean spring tides and generally increase the normal tidal range by a couple of inches.The Ash Wednesday Storm of 1962 which inundated the entire Atlantic coastline of the United States from the Carolinas to Cape Cod, resulting in a loss of 40 lives and over 500 million dollars of property damage, coincided with a perigean spring tide.
