All drought information is derived from the U.S. Drought Monitor. The percentage of commodities affected by drought is presented in a number of formats, including data tables, data graphs, maps, and animations. 

The U.S. Agriculture in Drought file is updated each Thursday by the U.S. Department of Agriculture’s Office of the Chief Economist, based on that morning’s U.S. Drought Monitor map. An archive of the weekly reports is available on the website.
