The U.S. Drought Monitor, produced weekly by the National Drought Mitigation Center with NOAA, USDA, and NASA input, classifies exceptional drought (D4) based on multiple indicators including precipitation deficits, soil moisture, streamflow, and vegetation health, representing the most severe category with historic rarity. As of the September 15 map, D4 covered about 1.7% of the U.S., concentrated in central Colorado, western Nebraska, southern Idaho, northern Nevada, northeastern Oregon, and parts of Texas and Oklahoma amid the warmest June–August on record and persistent dryness. Recent monsoon moisture offered limited western relief while Midwest rains improved some areas, but flash drought conditions expanded in the South. The next USDM release, expected around September 24 with data through September 22, will determine state-level D4 presence for the target week, with traders monitoring short-term forecasts for any rapid shifts in intensity or extent.
