Slosh display program

The intent of the Historical SLOSH run is to validate and improve the model; educate people about the timing of surge and winds; and educate people about historical storm surge levels. Download The following link contains everything needed to run the program, with data downloaded separately. Please verify that you get the full 84,, bytes. Note: The install program has the option to create short cuts, so please run it with the appropriate permissions.

The following link is a zip file of the installed files from the previous link. Its available in case there are problems with the previous installer. Probabilistic Approach - The Probabilistic Surge P-Surge product incorporates statistics of past forecast performances to generate an ensemble of SLOSH runs based on distributions of cross track, along track, intensity, and size errors.

The latest version explicitly models the astronomical tide. Composite Approach - Predicts surge by running SLOSH several thousand times with hypothetical hurricanes under different storm conditions. The MEOWs and MOMs play an integral role in emergency management as they form the basis for the development of the nation's evacuation zones. All water level observations, including SLOSH storm surge heights, are referenced as height above a vertical datum.

A vertical datum is an established surface that serves as a reference to measure or model heights and depths. All basins in the contiguous U.

It is important to note that when comparing water level observations e. For more information about datums please refer to the National Geodetic Survey. Storm surge inundation is the term used when referencing storm surge heights as height above ground level. NHC's storm surge forecast public advisory statements now reference storm surge as height above ground level. This means when NHC forecasts storm surge of 20 ft that means 20 ft above ground. Refer to the FAQ section for more information on storm surge inundation.

It aims to clearly and concisely depict the risk associated with the storm surge hazard. The experimental Potential Storm Surge Flooding Map is based on the forecast track, intensity, and size of a tropical storm or hurricane. The map is not a worst case scenario, but it shows a reasonable upper bound of potential flooding of normally dry land at particular locations due to storm surge. There is a 1-in chance that the storm surge flooding at any particular location could be higher than the values shown on the map.

Atlantic and Gulf of Mexico coastlines. These basins are centered upon particularly susceptible features: inlets, large coastal centers of population, low-lying topography, and ports. An example of a typical computational domain, or basin, is the New Orleans basin. SLOSH model coverage.
