Local Drought Statement:

Drought statements are normally issued for southwestern Iowa and eastern Nebraska when Severe Drought (D2) or worse conditions develop over the region and are expected to persist.  The latest Drought Information Statement from NWS Omaha/Valley is here.

The categories of drought are defined as follows:

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.
 


The U.S. Drought Monitor is a weekly collaborative effort between a number of federal agencies including NOAA/NWS, U.S. Department of Agriculture, and the National Drought Mitigation Center. Details and explanations of the Drought Monitor can found at the web site: http://droughtmonitor.unl.edu/

Note:  Drought categories are based on broad-scale indicators over "climate districts" (the gray division lines on the U.S. map above).  The central Illinois map below it attempts to delineate the drought categories on a smaller scale map.  Note that because the categories do not follow county lines, the "transition areas" on the central Illinois map may be larger than indicated above.  Also, 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 above.

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 and FAA observation sites, Iowa State and Illinois Cooperative Extension Services, the USDA, COE and USGS.
