Recent U.S. Drought Monitor data through early September 2026 show exceptional (D4) drought limited primarily to portions of Colorado, Nebraska, Wyoming, and adjacent Plains states, reflecting persistent long-term precipitation deficits and flash drought intensification in the South-Central region. A strengthening El Niño, with Niño-3.4 anomalies exceeding +1.8°C and over 90% probability of a very strong event through winter, favors enhanced monsoon moisture and potential relief across the Southwest and Rockies while supporting drier conditions farther north. Trader consensus on 10 or more states at 60% implied probability likely incorporates uncertainty around rapid model shifts and the next USDM release, which will incorporate the latest soil moisture, streamflow, and precipitation observations for the week of September 8.
