As with all remotely sensed data, all features should be verified with a site visit. The dataset should be used only as a screening-level tool for management decisions. Inundation is shown as it would appear during the highest high tides (excludes wind driven tides). This dataset illustrates the scale of potential flooding, not the exact location, and does not account for erosion, subsidence, or future construction. Counties were combined using the data downloaded from FEMA's Region II office.įederal Emergency Management Agency(FEMA) This FIRM data service allows users to view FIRMs for NJ. Digital elevation data is collected and an elevation surface created. This process results in a SLOSH grid that can be compared to the elevation grid. ![]() A MEOW is defined as a Maximum Envelope of Water, which is generated by compositing several hypothetical SLOSH runs, each of which has the same category, forward speed and direction. Maximum of Maximum or Maximum of MEOWs (MOM) SLOSH data is used. The Sea, Lake and Overland Surges from Hurricanes (SLOSH) model is a computerized numerical model developed by the National Weather Service (NWS) to estimate storm surge heights resulting from historical, hypothetical, or predicted hurricanes by taking into account the atmospheric pressure, size, forward speed, and track data. ![]() (description text source: FEMA MOTF website) HWMs and Surge Sensor data are used to interpolate a water surface elevation, then subtracted from the best available DEM, to create a depth grid and surge boundary by state. The Sandy Surge data were created from field-verified High Water Marks (HWMs) and Storm Surge Sensor data from the USGS through 14-February 2013.
