Indices used primarily during the snow season and in the West include snow water content, river basin precipitation, and the Surface Water Supply Index (SWSI). Additional indices used, mainly during the growing season, include the USDA/NASS Topsoil Moisture, Keetch-Byram Drought Index (KBDI), and NOAA/NESDIS satellite Vegetation Health Indices. Short-term drought indicator blends focus on 1-3 month precipitation. Drought Monitor more versatile than other drought indicators. It is this combination of the best available data, local observations and experts’ best judgment that makes the U.S. Additional indicators are often needed in the West, where winter snowfall in the mountains has a strong bearing on water supplies. The analysts producing the map also weigh the indices according to how well they perform in various parts of the country and at different times of the year. Because the ranges of the various indicators often don't coincide, the final drought category tends to be based on what the majority of the indicators show and on local observations. The drought severity classification table shows the ranges for each indicator for each dryness level. drought impacts which subjectively support and validate the indicators used.local condition reports and impact reports from more than 450 expert observers around the country.the original five key indicators along with several dozen other objective indicators.SL = Area contains both short- and long-term impactsĭrought intensity categories are based on:.L = Long-term, typically more than 6 months (hydrology, ecology).S = Short-term, typically less than 6 months (agriculture, grasslands).We indicate whether primary physical effects are for short- or long-term drought: Drought is defined as a moisture deficit bad enough to have social, environmental or economic effectsĭ0 areas are not in drought, but are experiencing abnormally dry conditions that could turn into drought or are recovering from drought but are not yet back to normal. D1 is the least intense level and D4 the most intense. The Drought Monitor map identifies areas of drought and labels them by intensity.
