How this page reads the Drought Monitor
- The figures are the U.S. Drought Monitor's own statistics (share of area in each category), read from its data service. The categories are theirs, unchanged. This site does not make its own drought assessment.
- The Drought Monitor gives each county a share in each category. A county's category here is the most severe one covering any part of it, with the share it covers. "Weeks" counts the weekly maps in a row, newest first, on which some of the county was at that category or worse.
- A new map is released every Thursday, valid for the Tuesday before. Every figure here carries that valid date. This site reads the new week once, after the Thursday release, and keeps it.
- Counties are matched to the Drought Monitor by their five-digit FIPS code. Connecticut is shown by its nine planning regions, which replaced its eight counties in 2022; the Drought Monitor's county statistics use the same planning regions.
The U.S. Drought Monitor is jointly produced by the National Drought Mitigation Center at the University of Nebraska-Lincoln, the United States Department of Agriculture, the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration. Map courtesy of NDMC.
