Based on dozens of indicators, experts make their best judgments of regional-scale drought conditions, and then check their assessments with experts in the field before publishing weekly drought maps. Experts also check whether areas are showing drought impacts such as water shortages and business interruptions. They check variables including temperatures, soil moisture, water levels in streams and lakes, snow cover, and meltwater runoff. The NDMC, based at University of Nebraska, Lincoln, leads the coordination of weekly drought monitor process and provides the maps, data and statistics to the public.Įach week, drought experts consider how recent precipitation totals across the country compare to their long-term averages. Drought Monitor began in 2000 and is a collaboration between the NDMC, NOAA and the USDA, who share the weekly author role for the product. Drought categories show experts’ assessments of conditions related to dryness and drought including observations of how much water is available in streams, lakes, and soils compared to usual for the same time of year. The USDM uses a five-category system, labeled Abnormally Dry or D0, (a precursor to drought, not actually drought), and Moderate (D1), Severe (D2), Extreme (D3) and Exceptional (D4) Drought. Drought Monitor (USDM) is a map that is updated each Thursday to show the location and intensity of drought across the country.
