Recent US Drought Monitor data valid through September 29, 2026, show exceptional (D4) drought covering roughly 1.3% of the contiguous United States, concentrated in central and eastern Texas, Oklahoma, and adjacent portions of Arkansas, Louisiana, and Mississippi. Persistent above-normal temperatures and prolonged precipitation deficits through August and September drove rapid intensification, expanding severe-to-exceptional classifications in the Southern Plains and Lower Mississippi Valley. Remnants of Hurricane Polo offered limited relief in some areas while raising localized flooding risks. The National Drought Mitigation Center, NOAA, and USDA partnership releases the next weekly map on October 8, incorporating soil moisture, streamflow, and vegetation indices that will determine D4 presence by state for the October 6 week. Traders monitor these updates closely because D4 thresholds reflect the most severe, multi-month deficits on the five-category scale.
