Service Description: Depicts the forecast arrival time of high water over the next 18 hours. This service is derived from the short-range configuration of the National Water Model (NWM) over the contiguous U.S. Shown are reaches that are expected to have flow at or above the high water threshold over the next 18 hours. Reaches are colored by the time at which they are forecast to reach high water. High water thresholds (regionally varied) were derived using the 40-year NWM v3.0 reanalysis simulation
Updated hourly.
This service is for internal use only for NOAA employees and requires access to view. Please do not share externally without prior approval from OWP as this service is experimental and undergoing regular developmental changes. For feedback or questions please reach out to GID directly via slack at national-water-center-gid or national-water-center-fim pages or reach out directly to derek.giardino@noaa.gov
