How to read these numbers
US Drought Monitor weekly cumulative area percentages for 2020–2025. A drought week means any county area above 0% at the selected threshold; it does not mean the entire county is affected. Frequency divides affected weeks by observed weekly maps. Streaks reset at missing weeks and the calendar-year boundary. D0 is abnormally dry, not drought. Area is distinct from population, water supply and future drought risk. The selected-county weekly timeline retains real source percentages.
Map colors span the minimum and maximum available values in your current filters. Point maps locate reference points and do not shade geographic boundaries. Nearby ordering uses straight-line point distance, not a travel route. Public links preserve statistical filters and place identifiers; calculation amounts and search text stay out of the URL.
