Drought in the Intermountain West

Drought and its impacts vary from region to region—due to differences in climate. In Arizona and across the Intermountain West region (Wyoming, Colorado, Utah, Arizona, and western New Mexico), drought onset may occur quickly and last a season, or begin gradually and last decades. The Rocky Mountain regions rely on winter snowpack to sustain cities, towns, agriculture, and recreation. In the Southwest, the summer monsoons help people, and livestock, get through the hot summer months.

The Colorado River is the largest perennial stream in the Intermountain West, feeding the two largest reservoirs in the United States. Winter snowpack in the Colorado Rockies usually sets the tone for drought conditions from year to year.

To help foster interstate coordination to cope with current and future droughts and growing water demands, NOAA’s National Integrated Drought Information System (NIDIS) launched the Intermountain West Drought Early Warning System (DEWS). The Intermountain West DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought.

Reach out to Gretel Follingstad, the Regional Drought Coordinator for this region, for more information, or sign up for the Intermountain West DEWS newsletter.

Arizona Current Conditions

A number of physical indicators are important for monitoring drought, such as precipitation & temperature, water supply (e.g., streamflow, reservoirs), and soil moisture. Learn more about monitoring drought.

Historical Drought Conditions in Arizona

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 Arizona 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.

U.S. Drought Monitor

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.
