The Experimental Flood Hazard Outlook (FHO) is intended to provide a coordinated inland hydrologic flood graphic for use in regional and national Impact-based Decision Support Services (IDSS) briefings and support broad messaging of flood threat to NWS stakeholders and Federal water partners. This experimental product combines a depiction of current flood conditions based on the latest river level observations with an assessment of flood risk leveraging various sources of NWS water resources forecast information. This experimental product will be issued daily (21Z), but will increase to twice daily (1130Z & 21Z) during tropical cyclone events.
The NWS is accepting comments through July 1, 2023 on the Experimental FHO as a replacement for the current Significant River Flood Outlook product. Please provide feedback on the Experimental FHO at:
