**Current conditions show D4 exceptional drought concentrated in a handful of western states, with recent expansions driven by persistent heat, high evaporative demand, and below-normal precipitation.** As of the August 27 U.S. Drought Monitor (data valid August 25), D4 covers about 1.5% of the U.S., primarily in northeastern Idaho (recent expansion), northeastern Oregon, far southern Idaho, western Nebraska, parts of Colorado, and small areas of Utah and southern California deserts, alongside D3 in southern Oregon and northern Washington. This stems from ongoing seasonal dryness across the Pacific Coast, Great Basin, and northern Rockies, where soil moisture and groundwater remain critically low. **Short-term forecasts and a strengthening El Niño introduce key uncertainty for the early September map.** Above-normal temperatures continue to stress the West, while precipitation outlooks favor drier conditions in the Northwest and mixed signals elsewhere; monsoon moisture may aid the Southwest. The CPC seasonal outlook anticipates persistence or expansion in parts of the Northwest/Great Plains but improvement in the Southwest through fall. With the next USDM reflecting data near September 1, trader consensus around 1–9 states (closely bunched at 45–47.5%) versus a slight edge for 10+ (54.5%) reflects the narrow margin between localized degradation and any late-summer relief that could limit D4 to fewer states. Historical analogs and model spread underscore the sensitivity to one or two additional states crossing into exceptional levels.
