Drought Conditions Briefing

Drought Monitor (Drought Severity)

Abnormally Dry (D0) - Going into drought: short-term dryness slowing planting, growth of crops or pastures; fire risk above average. Coming out of drought: some lingering water deficits; pastures or crops not fully recovered.

Moderate Drought (D1) - Some damage to crops, pastures; fire risk high; streams, reservoirs, or wells low, some water shortages developing or imminent, voluntary water use restrictions requested.

Severe Drought (D2) - Crop or pasture losses likely; fire risk very high; water shortages common; water restrictions imposed.

Extreme Drought (D3) - Major crop/pasture losses; extreme fire danger; widespread water shortages or restrictions.

Exceptional Drought (D4) - Exceptional and widespread crop/pasture losses; exceptional fire risk; shortages of water in reservoirs, streams, and wells, creating water emergencies.

Note: Drought categories are based on many factors over an area and may not necessarily match isolated, specific areas. Small-scale factors, such as localized heavy rain from thunderstorms, may affect the drought level over a small area, which may not necessarily be reflected in the maps.

The U.S. Drought Monitor is a weekly collaborative effort between a number of federal agencies including NOAA/ NWS, U.S. Dept. of Agriculture, and the National Drought Mitigation Center. The Drought Monitor is updated every Thursday based upon information valid on Tuesday.

Acknowledgements & Additional Information

The drought monitor is a multi-agency effort involving NOAA's National Weather Service and National Climatic Data Center, the USDA, State and Regional Center Climatologists and the National Drought Mitigation Center. Information for the drought statements has been gathered from NWS, FAA and CoCoRaHS observation sites, Iowa State and Illinois Cooperative Extension Services, the USDA, COE and USGS.
