Recent flash drought intensification across the Southern Plains, fueled by the contiguous U.S. record-warm June–August 2026 and persistent below-normal precipitation, has driven expansion of exceptional (D4) drought conditions, particularly in Texas where 3.6% of the state reached D4 by the September 15 U.S. Drought Monitor map. Authoritative USDM assessments, blending precipitation deficits, soil moisture percentiles, streamflow, and impacts, show national D4 coverage near 1.7% amid broader D1–D4 drought affecting nearly half the country. The next weekly map, released September 24 with data valid through September 22, will determine state-level D4 presence based on these objective indicators; traders should monitor National Weather Service precipitation totals and updated model guidance for any late-September relief that could alter category boundaries before resolution.

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 22, 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.
