Advancing Drought Science and Preparedness Across the Nation

The National Integrated Drought Information System (NIDIS) is a multi-agency partnership that coordinates drought monitoring, forecasting, planning, and information at national, tribal, state, and local levels.

Current Conditions and Outlooks

The U.S. Drought Monitor (USDM) is updated each Thursday to show the location and intensity of drought across the country. Drought categories show experts’ assessments of conditions related to dryness and drought including observations of how much water is available in streams, lakes, and soils compared to usual for the same time of year.

The Climate Prediction Center's (CPC's) Seasonal Drought Outlook is issued monthly on the third Thursday of each month. The Outlook predicts whether drought will emerge, stay the same, or get better in the next three months.
