Recent heavy rainfall from remnants of Hurricane Polo drove notable one- to two-category improvements across the Southern Plains and parts of the Southwest and High Plains in the latest U.S. Drought Monitor, released October 8 and valid through October 6. Exceptional (D4) drought currently occupies roughly 1% of the contiguous U.S., concentrated in limited portions of states including Arkansas, Idaho, Mississippi, Nebraska, and Nevada, where long-term precipitation deficits and low soil moisture persist. Drought worsened in the Lower Mississippi River Basin and parts of Texas amid mixed storm impacts. The next USDM update, expected October 15 and based on conditions through October 13, will incorporate any additional short-term precipitation or drying; forecasters note ongoing uncertainty in late-season rainfall patterns that could shift D4 boundaries before resolution.
