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 ...
As Tropical Storm Ian snakes toward the Sunshine State, officials worry about a potentially dangerous storm surge along the west coast of Florida and the panhandle.
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.

What makes the storm surge so dangerous? A combination of the storm surge and high tide could flood some parts of Florida with water levels as high as 15 feet above ground, including up to 8 feet ...
Helene's true toll will depend on where it makes landfall, and how its other effects like flooding, storm surge and tornadoes unfold. But its wind speed and category at landfall will especially ...
Storm surges can be produced by non-tropical storms, such as the "Halloween Storm" of 1991 and the Storm of the Century (1993), but the most extreme storm surge events occur as a result of extreme weather systems, such as tropical cyclones. Factors that determine the surge heights for landfalling tropical cyclones include the speed, intensity ...
