What drought has meant in Wyoming

The National Drought Mitigation Center's examples of impacts observed in Wyoming at each level of drought, starting with this week's worst here.

D3 Extreme drought This week

  • Snowpack is poor
  • Surface water for is inadequate for ranching and farming

D0 Abnormally dry

  • Fishing restrictions are issued

D1 Moderate drought

  • Creeks and rivers are low; less irrigation water is available
  • Fewer wildflowers bloom
  • Fire danger is elevated; fire and firework restrictions are implemented
  • Hay and forage yield is low; producers give supplemental feed to cattle

D2 Severe drought

  • Pasture conditions are poor; overgrazing is reported; hay is scarce; producers are selling cattle; dust increases
  • Trees and vegetation are stressed
  • Water pressure is low; well levels decline

Drawn from the Drought Impact Reporter and local observers.

Burn bans and water restrictions

The Drought Monitor does not issue burn bans or water restrictions. Platte County's officials, the state forestry or fire agency, and local water utilities set them, often once drought reaches D2 or dry fuels raise the fire danger. Check the county's emergency management office or fire marshal for a ban in force, and the alerts page for red flag warnings and fire weather watches.

This week in the High Plains

The Drought Monitor authors' narrative for the map of Sep 15, 2026, released Sep 17, 2026.

Eastern Kansas had above normal precipitation over the past week; this led to improvement in drought conditions in this area. Eastern Nebraska and eastern South Dakota also had decent rainfall and resulting improvement to drought. Other areas of South Dakota that missed out on the rain had drought degradation. Colorado had drought degradations in the center part of the state, with drought improvements in both the southwest and southeast parts. Extreme drought continues over much of Colorado and Wyoming, western Nebraska and the Dakotas, and in eastern North Dakota. Exceptional drought is observed over much of central Colorado as well as two localized areas in far western Nebraska.

Looking ahead

Over the next five days leading up to next Tuesday, above normal rainfall is forecast in south Florida as well as a large area in southern Wisconsin and Minnesota into eastern Iowa and northern Illinois. The latter area of forecasted rainfall continues to the east through central Michigan, the southern Great Lakes, Pennsylvania, New York, and much of central and southern New England. Other locations with rainfall in the forecast this week are in the Appalachian Mountains, the western Great Plains, and the Four Corners states. Unfortunately, most of Texas, Oklahoma, Arkansas, Louisiana, Mississippi, and Alabama are forecast to receive little rainfall. Dry conditions are also forecast in California, Nevada, and Washington. Much above normal temperatures are forecast to continue this week in the central and southern U.S.

The 6- to 10-day outlook (September 22-26, 2026) favors above normal temperatures continuing over nearly all of the continental United States. Areas most likely to be above normal are again the south into the southeast, plus the far north. Hawaii is also likely to be above normal. For precipitation, the Eastern Seaboard is likely to have above normal rainfall as is the Southwest. The central U.S. into the upper Midwest is likely to have below normal rainfall. Hawaii and Alaska are both likely to have above normal rain during this period.

What this means

The five categories the Drought Monitor draws, and how the map is made.

D0 Abnormally dry
Going into or coming out of drought.
D1 Moderate drought
Some damage to crops and pastures; water shortages developing.
D2 Severe drought
Crop or pasture losses likely; water restrictions imposed.
D3 Extreme drought
Major crop and pasture losses; widespread water shortages.
D4 Exceptional drought
Exceptional and widespread losses; water emergencies.

The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
