The U.S. Drought Monitor map for conditions valid August 25, 2026, released August 27, shows D4 exceptional drought expanding in the West, with notable areas in northeastern Idaho, parts of Utah, southern California deserts, western Nebraska, and portions of Colorado and Oregon, driven by persistent heat domes, below-normal precipitation, critically low soil moisture, and depleted groundwater. In the South, rapid degradation occurred under dry, hot conditions across Texas, Oklahoma, and adjacent states, while scattered convective rainfall brought localized improvements in the Southeast and some Midwest areas. The assessment integrates precipitation deficits, streamflow, satellite vegetation indices, and other indicators from NOAA, USDA, and NASA. With 47.56% of the U.S. and Puerto Rico in drought overall that week, the next weekly update on September 3 will incorporate any late-August rainfall shifts that could alter D4 extent.
