Persistent hot, dry conditions across the southern U.S. have driven recent intensification of exceptional (D4) drought, with the latest U.S. Drought Monitor (data valid September 29, 2026) showing D4 areas concentrated in central and eastern Texas, Oklahoma, and Arkansas amid severe-to-extreme classifications expanding into Louisiana, Mississippi, and Tennessee. The U.S. Drought Monitor, produced weekly by the National Drought Mitigation Center in partnership with NOAA, USDA, and NASA, classifies D4 based on multiple indicators including precipitation deficits, soil moisture, streamflow, and vegetation stress. Roughly 1.3% of the contiguous U.S. currently meets D4 criteria. The next map, released around October 8 and covering conditions near October 6, will incorporate any late-September or early-October rainfall from tropical remnants or frontal systems; NOAA’s October outlook favors drought improvement or removal across parts of the Southern Plains and Southeast, though model consensus on timing remains variable.
