Produced by the Climate Toolbox, the Historical Water Watcher is a tool that provides maps and summary tables of different drought types, such as agricultural and meteorological drought, for a location in the contiguous United States and enables easy comparison to a display of the current map of the U.S. Drought Monitor (USDM).
The tool allows users to investigate the different extreme conditions of drought in different categories, improving over the USDM's single drought classification for a region. The extreme wetness of a region can also be investigated in a symmetric extension of the USDM's drought classification. Through zoomable maps and location-specific graphs, a finer scale view of drought can be obtained than from the USDM.
