The U.S. Drought Monitor map is updated each Thursday to show the location and intensity of drought across the country. The map uses five classifications: abnormally dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought: moderate (D1), severe (D2), extreme (D3), and exceptional (D4).
This map is used by USDA to trigger disaster declarations and loan eligibility. Individual states and water supply planning may utilize additional information to inform their declarations and actions.
The U.S. Drought Monitor is a joint effort of the National Drought Mitigation Center, USDA, and NOAA. Learn more.
