Storm surge

Similar term(s): storm tide, storm wave.

Storm surge is a rise in coastal water level caused by a regional low pressure area and water pushed toward coastal shores by prolonged wind forces.

A storm surge can significantly raise the mean water level if combined with astronomical high tides. This rise in water level can cause severe flooding on coastal areas, particularly along shallow slopes along the shoreline.
