By 1990, Australia had developed its own storm surge model which was able to be run in a few minutes on a personal computer. [19] The Japan Meteorological Agency (JMA) developed its own Typhoon Model (TYM) in 1994, [20] and in 1998, the agency began using its own dynamic storm surge model. [21] A NOAA prediction for Hurricane Irene
The main storm surge forecast model in the Atlantic basin is SLOSH, which stands for Sea, Lake, Overland, Surge from Hurricanes. [25] It uses the size of a storm, its intensity, its forward motion, and the topography of the coastal plain to estimate the depth of a storm surge at any individual grid point across the United States. An accurate ...
ADCIRC is frequently coupled to a wind wave model such as STWAVE, SWAN, or WAVEWATCH III, especially in storm surge applications where wave radiation stress can have important effects on ocean circulation and vice versa. In these applications, the model is able to take advantage of tight coupling with wave models to increase calculation accuracy.
TALLAHASSEE, Fla. – Hurricane Helene is now predicted to reach Florida as a Category 4 hurricane, part of a frightening forecast of 130-mph winds and high storm surge that brings a dire scenario ...
Use the map below to see the hurricane center’s peak storm surge prediction: The National Hurricane Center predicts Tropical Storm Nicole will bring up to 5 feet of storm surge to parts of Florida.
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.

The National Hurricane Center's forecast cone for Tropical Storm Helene as of Sept. 24, 2024, at 2 p.m.
Winds increase within 12 hours of the center's approach, occasionally reaching hurricane force. The ocean's surface becomes whipped with foam. Small items begin flying in the wind. Within 6 hours of the center's arrival, rain becomes continuous and the storm surge begins to come inland. Within an hour of the center, the rain becomes very heavy ...
