Persistent heat and insufficient monsoon rainfall have sustained exceptional drought (D4) conditions across portions of the Intermountain West and northern Great Plains, with D4 areas concentrated in western Nebraska, eastern Colorado, northeastern Oregon, and far southern Idaho according to the U.S. Drought Monitor valid August 18–21, 2026. National coverage of D4 stands near 1.1 percent, reflecting long-term deficits in soil moisture, streamflow, and reservoir levels amid record July temperatures. Recent scattered rains brought limited relief or localized degradation in the Southern Plains and Midwest, while the weekly map update process—drawing on NOAA, USDA, and USGS inputs—will incorporate any precipitation through the August 25 period to determine state-level D4 designations. Forecasters note potential above-normal rainfall along the Atlantic coast but continued dryness risks in the West, with the next USDM release expected to clarify shifts 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.
