1 National Flood Conference April 22, 2009 Victor Hom Hydrologic Services Division Office of Climate, Water and Weather NOAA’s National Weather Service National Weather Service and Federal Emergency Management Agency’s National Flood Insurance Program Related Activities

2 2 National Flood Conference 2009 NWS and FEMA NFIP Related Activities Objectives: 1. Review the inter-relationship and inter- dependencies of the FEMA’s NFIP, USGS NSIP, and NOAA’s mission. 2. Discuss NOAA NWS efforts in Decision Support, Risk Communications, and Forecast Uncertainty and FEMA’s RISK MAP Strategy. 3. Provide update on NOAA NWS AHPS Flood Mapping Efforts.
