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]
The term "storm surge" in casual (non-scientific) use is storm tide; that is, it refers to the rise of water associated with the storm, plus tide, wave run-up, and freshwater flooding. When referencing storm surge height, it is important to clarify the usage, as well as the reference point. NHC tropical storm reports reference storm surge as ...
The storm surge, or the increase in sea level due to the cyclone, is typically the worst effect from landfalling tropical cyclones, historically resulting in 90% of tropical cyclone deaths. [2] The broad rotation of a landfalling tropical cyclone, and vertical wind shear at its periphery, spawns tornadoes.
Tampa is the single most vulnerable city in the US for hurricane storm surges — thanks to a mix of fatal factors colliding to create catastrophic conditions should it take a direct hit from a ...
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls , levees (also known as dikes), and other constructions ...
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 you end up with ...

Example of a SLOSH run A summary of strengths and limitations of SLOSH. Sea, Lake, and Overland Surge from Hurricanes (SLOSH) is a computerized model developed by the Federal Emergency Management Agency (FEMA), United States Army Corps of Engineers (USACE), and the National Weather Service (NWS), to estimate storm surge depths resulting from historical, hypothetical, or predicted hurricanes.
