Recent precipitation from remnants of Hurricane Polo and other systems has eased drought intensity across parts of the Southern Plains, Southwest, Northern Rockies, and Southeast, while conditions have worsened in the Lower Mississippi River Basin states amid limited rainfall between storms. The U.S. Drought Monitor classifies D4 Exceptional Drought based on integrated indicators including soil moisture percentiles, streamflow, and precipitation deficits relative to historical baselines, with roughly 1% of the contiguous U.S. currently in this category as of early October 2026 data. Persistent above-normal temperatures following the warmest June–August on record have sustained core drought areas in the West and South, creating uncertainty over whether the next weekly map—valid through mid-October—will show D4 persisting in 7–9 states, contracting to 5–6, or expanding to 10 or more depending on the latest model consensus and observational updates from NOAA and the National Drought Mitigation Center.
