Quarterly Climate Impacts and Outlook for the Western Region for December 2021–February 2022. Dated March 2022.

Above-normal temperatures were observed in mountain regions in California, Colorado, Arizona, and Oregon. Despite a wet December, high pressure-induced dry conditions during January and February created widespread below-normal conditions throughout the West. 

The National Weather Service developed 2022 Spring Hazard Outlooks in coordination with NOAA's National Centers for Environmental Information (NCEI) and National Integrated Drought Information System (NIDIS); High Plains Regional Climate Center; Midwestern Regional Climate Center; U.S. Department of Agriculture; and National Interagency Fire Centers' Geographic Area Coordination Centers. This outlook highlights the various spring hazards that could occur and potential impacts across the Mountain West.

Compared to one year ago, the area in drought in the western U.S. rose from 77% to 88%, while the area in Exceptional Drought (D4) dropped from 22% to 3%. December 2021 storms brought more than 200% of normal precipitation to a large area of California and Nevada and in the Rockies west of the Continental Divide. These storms improved the drought status by 1–2 categories, according to the U.S. Drought Monitor, throughout much of the region.
