Major High Tide Flooding Inundation Extent<\/span><\/p> <\/p> This dataset depicts the inundation extent of major high tide flooding, which is defined in the NOAA Technical Report NOS CO-OPS 086: Patterns and Projections of High Tide Flooding Along the U.S. Coastline Using a Common Impact Threshold. This threshold provides a national definition of coastal flooding and impacts for quantifying and communicating risk. It may deviate from NOAA National Weather Service (NWS) impact thresholds that take into account local flood risk and are used to issue NWS coastal flood watches, warnings, and advisories.<\/span><\/p> <\/p>
