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 ...
Storm surge is an above-normal rise in seawater along the coast caused by a tropical storm or hurricane and exceeding normal astronomical tides. "These tropical cyclones generate enough wind and ...
Already the ocean is swallowing beaches, roads and anything else in the way of Hurricane Florence's monstrous storm surge. WASHINGTON (AP) — Behold the awesome power of water. Already the ocean ...
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. [16] The relatively quick surge in sea level can move miles/kilometers inland, flooding homes and cutting off escape routes.
Tropical cyclones are characterised by very high wind speeds, heavy rainfall, and storm surges - short-term rises to sea-levels. This often causes widespread damage and flooding. Hurricanes can be ...
[2] [3] Fetch is used in geography and meteorology and its effects are usually associated with sea state and when it reaches shore it is the main factor that creates storm surge which leads to coastal erosion and flooding. [citation needed] It also plays a large part in longshore drift. [citation needed] [clarification needed]
Storm surge: A storm surge is a rise in ocean water levels generated by a storm that is over and above a normal tide. You can estimate a storm surge by subtracting the normal tide from the storm tide.
