Recent hot, dry conditions across parts of the southern U.S. have driven localized expansion of exceptional drought (D4) on the U.S. Drought Monitor, with the latest map (data valid September 8, 2026) showing D4 in a small portion of Arkansas—marking the first such designation there since 2012—and roughly 1.5–1.8% of the continental U.S. overall. D4 represents the 0–2nd percentile of dryness relative to historical norms, reflecting severe impacts on water supplies, agriculture, and ecosystems assessed via precipitation deficits, soil moisture, streamflow, and expert input from the National Drought Mitigation Center, USDA, NOAA, and NASA. The next weekly USDM update, expected around September 17, will incorporate observations through mid-September and any short-term rainfall shifts from ongoing weather patterns, which could alter D4 boundaries in drought-prone southern and western regions.

D4 area below 0.05% is treated as cartographic noise at state borders and resolves "No".
Alabama carries a market in May through November, so this market exists for the week valid September 15, 2026. Weeks outside that window have no Alabama market and make no claim about Alabama's drought.
Each USDM release covers the seven-day period ending Tuesday at 8:00 AM ET and is published the following Thursday.
Resolution is based on the first published US Drought Monitor release for the listed week. Subsequent revisions will not be considered; the first published release is final.
If the US Drought Monitor has not been published by 11:59 PM ET on the day following the scheduled publication date, this market will resolve to "No".
The resolution source for this market is the US Drought Monitor at droughtmonitor.unl.edu.
