Recent hot and dry conditions across the central and southern U.S., following the warmest June-August on record, have driven flash drought intensification and expansion of exceptional (D4) drought on the U.S. Drought Monitor. As of the September 17 map (data valid September 15), D4 covers roughly 1.7% of the contiguous U.S., with notable areas in central Colorado (15%+ of the state), northern North Carolina counties, western Nebraska, southern Idaho, northern Nevada, northeastern Oregon, and parts of Texas and Oklahoma. The next USDM update, released September 24 with data through September 22, will determine outcomes for the target week. Limited rainfall is forecast across most of these regions through mid-week, alongside above-normal temperatures, supporting persistence of D4 conditions while any late-week precipitation could limit further degradation.
