Why are storm surge zones updated?

Zones are updated to incorporate new, higher resolution storm surge model output from the National Weather Service. These data, combined with improved topographic data, and information from actual events, allow the City to more accurately define areas most at risk of flooding due to storm surge from a hurricane.

What is the most serious hurricane hazard?

The storm's driving winds and torrential rains can cause massive and dangerous flooding in low-lying and poor-drainage areas. However, storm surge — the dome of seawater pushed forward by the oncoming storm — is the most serious hurricane-related hazard.

Can you use a FIRM zone to evacuate?

Residents should not use the FIRM zones to determine the need to evacuate. The City will determine which of the hurricane evacuation zones (from zone 1 up through zone 6) should be evacuated based on the characteristics of an actual storm as it is approaching the city.

What is the NOAA model for storm surge?

The National Oceanic and Atmospheric Administration (NOAA), specifically the National Weather Service's (NWS) National Hurricane Center (NHC), utilizes the hydrodynamic Sea, Lake, and Overland Surges from Hurricanes ( SLOSH) model to simulate storm surge from tropical cyclones. Storm surge information is provided to federal, state, and local partners to assist in a range of planning processes, risk assessment studies, and operational decision-making. In regards to the former, 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 assess and visualize storm surge risk under varying conditions. While MEOWs and MOMs provide a local assessment of storm surge risk, they do not provide a seamless perspective of the hazard owing to the many discrete SLOSH grids. This section briefly describes the scientific techniques used to create the seamless inundation maps for Category 1-5 hurricanes using the SLOSH MOM product as well as a description of the datasets and map viewer available to the public.

Where are storm surge maps available?

Storm surge hazard maps are available for Texas to Maine, Puerto Rico, USVI, Hawaii, and Hispaniola. The data are available in GeoTIFF ( http://trac.osgeo.org/geotiff/) format for use in Geographic Information Systems (GIS) software. Comprehensive metadata are provided with each GIS file describing the data and its limitations. Storm surge inundation datasets are created using the high tide scenario SLOSH MOM products for all regions. Each dataset contains an ESRI World File (.tfw) and metadata .xml file. These GeoTIFFs are 8-bit unsigned integer raster datasets that correspond to 1 ft inundation bins (e.g., Class Value 1 corresponds to the 0-1 ft inundation bin, Class Value 2 corresponds to the 1-2 ft inundation bin, and so on). The maximum Class Value is 21, and inundation in excess of 20 ft is assigned a Class Value of 21. A Class Value of 99 is assigned to leveed areas. A more detailed description of the data can be found in the associated metadata.

Where is storm surge flooding?

This national depiction of storm surge flooding vulnerability helps people living in hurricane-prone coastal areas along the U.S. East and Gulf Coasts, Puerto Rico, U.S. Virgin Islands (USVI), Hawaii, and Hispaniola to evaluate their risk to the storm surge hazard. These maps make it clear that storm surge is not just a beachfront problem, ...

Which states are vulnerable to hurricanes?

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 increases with increasing hurricane category.

Is a large bay a storm surge risk?

Large bays, tidal rivers, etc. are extremely vulnerable to storm surge flooding. These data and this approach taken to inform the public of storm surge risk are valuable to federal, state, and local NOAA partners, academic, private, and other various organizations.
