Definition of Storm surge

Storm surge: The onshore rush of sea or lake water caused primarily by the high winds that are associated with a landfalling hurricane, typhoon, or tropical cyclone and secondarily by the low pressure of the storm. The term tidal surge is often mis-used to describe storm surge, but a storm surge is independent of the usual tidal ebb and flow.
