A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. [1]
NHC tropical storm reports reference storm surge as water height above predicted astronomical tide level, and storm tide as water height above NGVD-29. In areas where there is a significant difference between low tide and high tide, storm surges are particularly damaging when they occur at the time of a high tide. In these cases, this increases ...
What is storm surge? Storm surge occurs when there’s a departure from normal tide levels, said Pablo Santos, a meteorologist at the National Weather Service in Miami. “Whatever amount of water ...

A record storm surge can occur near and just to the south of where the eye moves ashore. The storm surge will drop off significantly north of where the eye rolls in but can be delayed and swiftly ...
The main cause of storm-related fatalities had been shifting away from storm surge and towards freshwater (rain) flooding. [31] However, the median death rate per storm had increased through 1979, with a lull during the 1980–1995 period. This was due to greater numbers of people moving to the coastal margins and into harm's way.
