Recent U.S. Drought Monitor data valid through mid-to-late August 2026 indicate persistent D4 exceptional drought in portions of Colorado, western Nebraska, northeastern Oregon, and southern Idaho, driven by multi-month precipitation deficits, record summer heat, and a weak monsoon across the Intermountain West. Official analyses from NIDIS and NOAA note that while isolated rains improved some D2–D3 areas in the Plains and Midwest, long-term deficits and low reservoir levels in the Colorado River Basin have sustained the highest-intensity category. The weekly USDM release, blending precipitation, soil moisture, streamflow, and vegetation indices, determines state-level D4 presence; traders should monitor the next map update and any late-August rainfall anomalies that could shift 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 August 25, 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.
The resolution source for this market is the US Drought Monitor at droughtmonitor.unl.edu.
