Sea, Lake, and Overland Surge from Hurricanes (SLOSH) Inundation for Categories 2 and 4

Published by U.S. EPA Office of Research & Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: January 27, 2026 | Last Modified: 2016-10-13T00:00:00.000+00:00
The file geodatabase (fgdb) contains the Sea, Lake, and Overland Surge from Hurricanes (SLOSH) Maximum of Maximums (MOM) model for hurricane categories 2 and 4. The EPA Office of Research & Development (ORD) modified the original model from NOAA to fit the model parameters for the Buzzards Bay region. The models show storm surge extent for the Mattapoisett area and therefore the flooding area was reduced to the study area. Areas of flooding that were not connected to the main water body were removed. The files in the geodatabase are: Cat2_SLR0_Int_Feet_dissolve_Mattapoisett: Current Category 2 hurricane with 0 ft sea level rise Cat4_SLR0_Int_Feet_dissolve_Mattapoisett: Current Category 4 hurricane with 0 ft sea level rise Cat4_SLR4_Int_Feet_dissolve_Mattapoisett: Future Category 4 hurricane with 4 feet sea level rise The features support the Weather Ready Mattapoisett story map, which can be accessed via the following link: https://epa.maps.arcgis.com/apps/MapJournal/index.html?appid=1ff4f1d28a254cb689334799d94b74e2
