Recent flash drought intensification across the South-Central U.S., combined with persistent heat and precipitation deficits along the North Dakota–South Dakota–Minnesota border and parts of the Northeast, has driven expansion of extreme (D3) to exceptional (D4) drought on the U.S. Drought Monitor. As of the September 1 map (valid through September 1, 2026), D4 covered roughly 1.4% of the contiguous U.S., concentrated in areas with multi-week rainfall shortfalls and elevated evaporative demand. The National Drought Mitigation Center, NOAA, and USDA integrate station data, soil moisture percentiles, streamflow, and vegetation indices to classify these conditions. The next USDM release, based on data through September 8, will reflect any late-summer rainfall or continued drying; short-term forecasts from the National Weather Service will be key inputs for potential category shifts in affected states.
