Significant River Flood Outlook

This Flood Outlook is intended to provide a general outlook for significant river flooding. It is not intended to depict all areas of minor flooding or small-scale events such as localized flooding and/or flash flooding.

U.S. Drought Monitor

U.S. Drought Monitor

The U.S. Drought Monitor is produced in partnership between the National Drought Mitigation Center at the University of Nebraska-Lincoln, the United States Department of Agriculture, and the National Oceanic and Atmospheric Administration.

About Product Suite

Probabilistic Guidance

This product provides a probabilistic forecast of rainfall over the continental United States in 6-hour and 24-hour increments issued by the Weather Prediction Center.

Probabilistic Guidance

 

Meteorological Model Ensemble River  Forecasts (MMEFS)

The purpose is to provide users with a short-term situational awareness by providing the probabilistic exceedence information relative to NWS flood categories and providing the ensemble river forecasts that in turn show a range of outcomes.
