Resource Information

Agency:

NOAA National Weather Service

Resource:

(NOAA NWS) National Water Model (NWM)

Overview:

In August 2016, NOAA NWS Office of Water Prediction (OWP) released version 1.0 of the NWM to enhance and expand NOAA’s water flow forecasts, which previously had been available for approximately 4,000 river locations with stream gages predominantly operated by USGS. The new model expands forecasts to 2.7 million stream locations nationwide and leverages the full network of nearly 8,000 USGS stream gauges and NOAA’s investment in atmospheric modeling. The NWM will provide high-resolution forecasts of soil moisture, surface runoff, snow water equivalent, and other parameters. With implementation of Version 2.0 of the NWM, forecasts are now also available for Hawaii.

Funding Information:

  • 100 percent federally funded.
  • NWM output is freely available in various resolutions (1 km, 250 m, and along a point at a channel or reservoir)
