Recent degradations from persistent heat, low soil moisture, and limited rainfall have expanded exceptional (D4) drought across parts of the West, including northeastern Idaho and small areas of Utah and southern California deserts, according to the U.S. Drought Monitor valid August 25, 2026. Broader intensification occurred in the Southern Plains, Upper Midwest, and North Dakota, with 1.5% of the contiguous U.S. now in D4 amid 47.5% overall drought coverage. The next USDM map, using data through early September, will reflect any late-August changes from monsoon activity or heat waves. A developing strong El Niño may influence longer-term relief but offers limited near-term impact on D4 thresholds.
