Subject: Updated: Soliciting Comments on the Experimental Flood
Hazard Outlook (FHO) Product through June 30, 2025

Updated to extend the comment period.

The NWS is soliciting comments and feedback on the Experimental
Flood Hazard Outlook (FHO) through June 30, 2025. The 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.
These partners include the Federal Emergency Management Agency
(FEMA), the United States Army Corps of Engineers (USACE), and
the United States Geological Survey (USGS). The intent of this
product is to replace the current Significant River Flood
Outlook product when the FHO becomes operational.

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. These sources of information
include National Water Model guidance, official River Forecast
Center (RFC) deterministic and probabilistic forecasts, and
Weather Prediction Center (WPC) excessive rainfall outlooks.

This experimental product is issued twice daily, typically
around 1200 UTC during Daylight Saving Time / 1300 UTC during
Standard Time and typically around 2100 Coordinated Universal
Time (UTC).

The graphical depiction of the flood threat with key messages is
made available as an interactive GIS service and a static
graphic linked below the interactive map on the National Water
Prediction Service (NWPS):
