What drought has meant in Montana

The National Drought Mitigation Center's examples of impacts observed in Montana at each level of drought.

D0 Abnormally dry

  • Fire danger increases
  • Soil moisture is low, dryland crop germination is poor, pastures are dry
  • Streamflow is low, affecting recreation fishing

D1 Moderate drought

  • Fire restrictions are implemented
  • Producers feed livestock supplemental hay; crops are stressed and growth is poor

D2 Severe drought

  • Fire count and danger are high; air quality is poor, with dust and smoke
  • Hay and crop yields are low; hay quality is poor; subsoil moisture is nonexistent
  • Livestock ponds are low or dry; water quality is monitored; wells are stressed
  • Trees and landscaping show signs of stress and lose leaves

D3 Extreme drought

  • Agriculture and local business face economic loss
  • Cattle have very little water; water quality is toxic
  • Crops are not harvestable; winter pasture is opened for grazing; producers are hauling water and buying expensive supplemental feed, culling cattle and selling early; soil has large cracks; fields are bare
  • Fire restrictions increase

D4 Exceptional drought

  • Drought hotlines are in place
  • Fire risk is extremely high; fires are widespread
  • Pasture loss is widespread; crops are destroyed
  • Property is closed for hunting

This week in the West

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

An area from southwestern Oregon to central Washington into northern Idaho and Montana received some welcome rainfall during the week. The rain resulted in regional improvements in drought conditions. One location that just missed out was in northwest Washington on the Canadian border, resulting in a drought degradation, where continued low streamflows were observed. There were also areas on the California-Nevada border and central Arizona with drought degradation that also received little-to-no rainfall. Extreme drought is shown over much of central Oregon, central Utah, southern Idaho down into northern Nevada, and small areas in northern Washington and southern Arizona. Exceptional drought continues in southern Idaho, northern Nevada, and northeastern Oregon.

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.
