Using the Hydrologic Ensemble Forecast Service (HEFS)

Using the Hydrologic Ensemble Forecast Service (HEFS)
The lesson is intended to help NOAA's National Weather Service facilitate forecasters' use of ensemble forecast information in hydrology. The lesson provides information about the benefits and limitations of the Hydrologic Ensemble Forecast Service (HEFS), explains the sources of uncertainty (meteorological inputs and hydrologic modeling), and demonstrates how to interpret a HEFS product for hydrologic analysis and forecasting.
