Recent heavy precipitation, including remnants of Hurricane Polo across the Southern Plains plus scattered storms in the Southwest and Southeast, has driven notable one- to two-category improvements in the latest U.S. Drought Monitor, reducing overall drought coverage to 46% of the contiguous U.S. while some Lower Mississippi and northern areas saw localized worsening. A developing strong El Niño favors additional southern moisture through October, yet timing, exact rainfall totals, and soil-moisture recovery rates introduce meaningful uncertainty for D4 persistence or emergence. The next USDM release, reflecting conditions through mid-October, will resolve the market, with trader odds clustered tightly because small regional shifts could swing the state count across the leading bins.
