Mitigate Flood Impacts by Demonstrating Improved Decision Support Services to Emergency Managers

A Department of Commerce Agency Priority Goal (APG) is a two-year initiative to improve performance of a specific high-priority policy or management area. Each APG has a goal leader, results-based goal statement, strategies, a plan of actions and milestones, and measurable performance targets. Most importantly, accomplishing an APG will have a significant positive impact on the lives of all U.S. citizens. This is one of five APGs the Department of Commerce has for 2020-2021.
Goal Leader: Dr. Neil Jacobs, Assistant Secretary of Commerce for Environmental Observation and Prediction, performing the duties of Under Secretary of Commerce for Oceans and Atmosphere
Goal Statement: By September 30, 2021, NOAA National Weather Service will improve its flood related decision support services by expanding the demonstration of a new flood inundation mapping capability to at least an additional 10%* of the U.S. continental population residing in flood-vulnerable freshwater basins.
Progress Update Summary: During Q2 FY20, completed key milestone - Initiate Flood Inundation Mapping (FIM) techniques using the National Water Model (NWM) guidance and the River Forecast Center (RFC) official forecast for Northeast River Forecast Center (NERFC) domain.

Learn More About U.S. Flooding and Flood Safety: Flash floods are the #1 weather-related killer in the United States. Even 6 inches of fast-moving flood water can knock you off your feet, and a depth of 2 feet will float your car! NEVER try to walk, swim, or drive through such swift water. If you come upon flood waters, STOP! TURN AROUND AND GO ANOTHER WAY.  
Current Flood Mapping Capability: Static Inundation Map libraries at ~180 river locations across the United States. Provides the spatial extent and depth of flood waters. Displays inundation maps for levels from minor flooding through flood of record. Limited spatial coverage, resource intensive, at small number of USGS stream gauge locations.

Next Steps - NWM Enabled Flood Mapping Capability: The high spatial and temporal resolution capabilities of the National Water Model (NWM) coupled with high resolution hydrography datasets will allow us to provide real-time flood inundation mapping capabilities at neighborhood level in a more consistent and timely way.
