The National Oceanic and Atmospheric Administration (NOAA), particularly the National Weather Service's (NWS) National Hurricane Center (NHC), utilizes the hydrodynamic Sea, Lake, and Overland Surges from Hurricanes (SLOSH) type to simulate storm surge from tropical cyclones. Storm surge data is equipped to federal, state, and local partners to lend a hand in a spread of making plans processes, risk assessment studies, and operational decision-making. In regards to the previous, tens of thousands of climatology-based hypothetical tropical cyclones are simulated in each SLOSH basin (or grid), and the potential storm surges are calculated. Storm surge composites – Maximum Envelopes of Water (MEOWs) and Maximum of MEOWs (MOMs) – are created to evaluate and visualize storm surge chance underneath varying stipulations. While MEOWs and MOMs supply an area review of storm surge chance, they don't provide a seamless perspective of the danger owing to the many discrete SLOSH grids. This section in brief describes the scientific techniques used to create the seamless inundation maps for Category 1-5 hurricanes using the SLOSH MOM product as well as an outline of the datasets and map viewer to be had to the general public.SLOSH Storm Surge Modeling
SLOSH has been used operationally for more than 3 many years. Over this time, SLOSH has supplied precious and accurate storm surge forecasts. For planning functions, the NHC makes use of a consultant pattern of hypothetical storms to estimate the close to worst–case scenario of flooding for each and every hurricane class. These SLOSH simulations are used to create a set of operational and planning products.
The NHC supplies two merchandise in response to hypothetical hurricanes: MEOWs and MOMs. MEOWs are created by way of computing the maximum storm surge because of up to 100,000 hypothetical storms simulated through each SLOSH grid of varying forward speed, radius of maximum wind, intensity (Categories 1-5), landfall location, tide level, and storm course. A MEOW product is created for each aggregate of category, forward velocity, storm direction, and tide point. SLOSH products exclude Category 5 storms north of the NC/VA border and for Hawaii. For each and every storm combination, parallel storms make landfall in Five to ten mile increments along the coast inside the SLOSH grid, and the most storm surge footprint from every simulation is composited, maintaining the most peak of storm surge in a given basin grid mobile. These are called MEOWs and no single storm will produce the regional flooding depicted in the MEOWs. SLOSH style MOMs are an ensemble product of maximum storm surge heights. SLOSH MOMs are created for every storm class by keeping the utmost storm surge worth in each grid cellular for all the MEOWs, regardless of the ahead pace, storm trajectory, or landfall location. SLOSH MOMs are available for imply tide and high tide eventualities and constitute the near worst-case situation of flooding below ideal storm stipulations. A high tide preliminary water level used to be used for the storm surge hazard maps.
SLOSH employs curvilinear polar, elliptical, and hyperbolic telescoping mesh grids to simulate the storm surge danger. The spatial protection for each and every SLOSH grid ranges from an space the scale of a few counties to a few states. The decision of particular person grid cells inside of each and every basin levels from tens to hundreds of meters to a kilometer or more. Sub–grid scale water features and topographic obstructions reminiscent of channels, rivers, and cuts and levees, boundaries, and roads, respectively are parameterized to fortify the modeled water ranges. Figure 1 shows the SLOSH basins used to create the surge hazard maps.

In locations that experience a steep and slim continental shelf, wave setup could be a substantial contributor to the full water point rise noticed all the way through a tropical cyclone. Wave setup is defined as the rise in mean water point due to momentum switch to the water column by means of waves which are breaking or differently dissipating their energy. Through NOAA's Integrated Ocean Observing System (IOOS) Coastal and Ocean Modeling Testbed (COMT) the SLOSH model has been loosely coupled to the Simulating Waves Nearshore (SWAN) third-generation wave style, developed at Delft University of Technology (http://www.swan.tudelft.nl/), for storm surge modeling programs in island areas corresponding to Puerto Rico, USVI, and Hawaii. In these locations, SLOSH+SWAN simulations have been performed to create MEOW and MOM merchandise that account for the increase in the mean water level because of wave setup.Storm Surge and Wave Modeling in Hispaniola
Through the USAID/WMO Coastal Inundation and Flooding Demonstration Project for the Island of Hispaniola, the SLOSH fashion has been coupled with an effective parametric wind wave model courtesy of NOAA/NCEP/EMC. In this location, SLOSH+Wave simulations had been performed to create MEOW and MOM merchandise that account for the rise in the imply water level because of wave setup. Data has been processed through the National Hurricane Center (NHC) Storm Surge Unit.Digital Elevation Model
An correct digital elevation model (DEM) takes substantial time, sources, and expertise to broaden and is needed to compute inundation. Two datasets had been used to create the DEM:The NOAA Office for Coastal Management (OCM) high-resolution seamless raster elevation dataset (https://coast.noaa.gov/slr/) U.S. Geological Survey (USGS) three-D Elevation Program (3DEP) dataset (http://nationalmap.gov/3DEP/index.html).
To create this map for the USA Gulf and East Coasts, the 3DEP and OCM DEMs have been resampled to 1 arc-second (about 30 m) the use of a bilinear interpolation and mosaicked together to produce a continuing raster elevation dataset. The blended DEM used to be smoothed by the use of an area circle way with a radius of two grid cells using the focal statistics tool in Esri ArcGIS Platform. This minor point of smoothing supplies a less noisy map this is easier to interpret, and ultimately a seamless DEM for storm surge inundation mapping.
The NOAA OCM high-resolution DEMs have been used for Puerto Rico, USVI, and Hawaii. The native grid cellular measurement for that information is ready 3m and for the needs of this analysis, that information was resampled to a grid cellular dimension of about Nine meters.
In spaces outdoor of the U.S., equivalent to Hispaniola, the research makes use of TanDEM-X (TDX) DEM information provided through German Aerospace Center (DLR). Resolution of TDX DEM is 0.Four arc seconds in latitudinal path and varies in longitudinal direction between 0.4 arc seconds (equator) and four arc seconds (85 levels N/S) (Wessel, 2016). In partnership with the Department of Earth and Environment/International Hurricane Research Center at the Florida International University, the raw knowledge was once filtered to take away non-ground features.Seamless Mapping Methodology
The procedure to create storm surge inundation maps from the existing SLOSH MOM merchandise calls for a number of technical steps. First, the usable spaces of the SLOSH grids have been lowered to forget about spurious information alongside the grid obstacles. The SLOSH basins have substantial overlap to allow for complete storm surge protection for making plans and operations. Merging these basins into a continuing product requires specialised technical issues. Since the grid boundaries yield unreliable knowledge, basin overlap was once minimized, and the high-resolution and middle parts of grids had been retained. The process used herein leveraged both SLOSH basin development and surge modeling expertise at NHC. Second, the maximum water levels in every MOM had been merged onto a uniform grid for processing. The data were merged onto the NWS National Digital Forecast Database (NDFD) Lambert Conformal projected grid with a horizontal resolution of roughly 625 m (the actual resolution varies by latitude). Lastly, the merged MOM grids had been processed thru Esri ArcGIS to subtract the land elevation and create a seamless raster of inundation. It will have to be famous that the SLOSH MOM storm surge hazard knowledge used to create those maps are constrained via the extent of the SLOSH grids. High-quality maps are very important for efficient chance conversation.Concluding Remarks
This page outlines the way to merging the SLOSH MOM products to create a continuing view of storm surge inundation and possibility for Category 1-5 hurricanes. Using social science analysis, the sparsely derived and excessive resolution inundation maps provide a way for efficient risk communication and analysis. The maps show that all coastal states from Texas to Maine, as well as the island of Puerto Rico, USVI, Hawaii, and Hispaniola are vulnerable to storm surge inundation, and the risk significantly will increase with increasing storm category. Locations along the Gulf of Mexico are extraordinarily liable to storm surge, in the case of both height and inland extent because of a large and flat continental shelf over the vast majority of the area and low-lying land elevations extending neatly inland. Puerto Rico, USVI, Hawaii, and Hispaniola are also vulnerable to storm surge and wave affects. Large bays, tidal rivers, and so forth. are extraordinarily susceptible to storm surge flooding. These knowledge and this approach taken to inform the general public of storm surge risk are treasured to federal, state, and local NOAA companions, instructional, private, and different various organizations.Population at Risk from Storm Surge Inundation
Knowing the full inhabitants suffering from storm surge inundation is necessary for overall awareness and public protection. The inhabitants knowledge are based on the 2010 census block demographic data. In a worst-case scenario, roughly 24 million other folks alongside the East and Gulf coasts are in danger from storm surge flooding.
