Service Description: Depicts the magnitude of the peak National Water Model (NWM) streamflow forecast over the next 18 hours where the NWM is signaling high water. This service is derived from the short-range configuration of the NWM over the contiguous U.S. Shown are reaches with peak flow at or above high water thresholds. Reaches are colored by the annual exceedance probability (AEP) of their forecast peak flow. High water thresholds (regionally varied) and AEPs were derived using the 40-year NWM v3.0 reanalysis simulation.
Updated hourly.
