The U.S. Drought Monitor depicts the location and intensity of drought across the country. The map uses 5 classifications: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4).
This map is used by the U.S. Department of Agriculture to trigger some disaster declarations and loan eligibility. Individual states and water supply planning may use additional information to inform their declarations and actions. Learn more.

The U.S. Drought Monitor depicts the location and intensity of drought across the country, using 5 classifications (D0–D4). Green hues indicate conditions improved, while yellow/orange hues indicate degradations.
The Multi-Indicator Drought Index (MIDI) looks at current drought conditions across the U.S. by integrating several key drought indices on precipitation and moisture into one objective, computer-generated map.
The Short-Term MIDI approximates drought impacts from changes in precipitation and moisture over a short-term timeframe (looking back up to 90 days), such as impacts to non-irrigated agriculture, topsoil moisture, and range and pasture conditions. Long-term droughts (lasting months to years) can have different impacts.

Drought in the Missouri River Basin
In Montana and across the Missouri River Basin (MRB), drought is a common climate event. Prolonged droughts in the 1930s and 1950s substantially affected water supplies, agriculture, energy, transportation of goods, and ecosystems. More recently, short duration droughts wreaked havoc on the MRB. The intense 2012 summertime drought surprised the region, as flooding was expected to continue into a second year following the devastating floods of 2011. Flash drought in the U.S. Northern Plains and Canadian Prairies in 2017 resulted in $2.6 billion of agricultural losses alone. In 2020-2021, drought affected the same area and was a multi-billion-dollar event that had wide-reaching impacts on the region’s communities, ecosystems, water resources, and agricultural systems.
Partly in response to the floods of 2011 and then the extreme and rapidly evolving drought in 2012, NOAA’s National Integrated Drought Information System (NIDIS) and partners established the Missouri River Basin Drought Early Warning System (DEWS) in 2014. The Missouri River Basin DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought. Western Montana is also part of the Pacific Northwest DEWS.

Historical Drought Conditions for Montana
Drought is a normal climate pattern that has occurred in varying degrees of length, severity, and size throughout history. Below, you can look back at past drought conditions for Montana according to 3 historical drought indices. The U.S. Drought Monitor is a weekly map that shows the location and intensity of drought across the country since 2000. The Standardized Precipitation Index (SPI) is a monthly depiction of drought based on precipitation (with data going back to 1895). And the paleoclimate data uses tree-ring reconstructions to estimate drought conditions before we had widespread instrumental records, going back to the year 0 for some parts of the U.S. View more historical conditions.

The U.S. Drought Monitor (2000–present) depicts the location and intensity of drought across the country. Every Thursday, authors from NOAA, USDA, and the National Drought Mitigation Center produce a new map based on their assessments of the best available data and input from local observers. The map uses five categories: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4). Learn more.
| Value | Map Hex Color | Description |
|---|---|---|
| D4 | #730000 | D4 (SPI of -2.0 or less) The 9-month Standardized Precipitation Index (SPI) value for this location is -2.0 or less, indicating exceptional drought (D4) conditions. |

| W4 | #0000AA | W4 (SPI of 2.0 or more) The Standardized Precipitation Index (SPI) value for this location is 2.0 or greater, indicating exceptional wet (W4) conditions. |
Drought results from an imbalance between water supply and water demand. The Standardized Precipitation Index (SPI) measures water supply, specifically precipitation. SPI captures how observed precipitation (rain, hail, snow) deviates from the climatological average over a given time period—in this case, over the 9 months leading up to the selected date. Red hues indicate drier conditions, while blue hues indicate wetter conditions. Data are available monthly from 1895–present.

In paleoclimatology, proxy climate data (e.g., tree rings, ocean sediments) can allow us to reconstruct past climate conditions before we had widespread instrumental records. The Living Blended Drought Atlas, shown here, estimates average drought conditions each summer (June–August) as far back as the year 0 by combining tree-ring reconstructions and instrumental records. Red hues indicate drier conditions, while blue hues indicate wetter conditions.
