Animated Indicator Maps for U.S. Drought Monitor National Climatic Data Center

The U.S. Drought Monitor is an interagency drought monitoring tool that is issued weekly. U.S. Drought Monitor Animation: 6-week or 12-week

This page has been created to help in the preparation of the U.S. Drought Monitor. (The graphics linked to from this page are operational products produced by several different organizations and agencies. The quality control applied to these graphics varies from graphic to graphic and some of the graphics are experimental.) Some of the indicators that are examined to produce the U.S. Drought Monitor include the following:
