Each card reads the share of the state in drought, D1 or worse, from the weekly US Drought Monitor map; each state's page lists the counties we track there. The Monitor's five categories run from D0, abnormally dry and not yet drought, to D4, exceptional drought; the guide to what D0 to D4 mean explains each class and why the map lags a fast-moving storm.
