On 20 April 2022, the Tunnel Fire, the biggest incident of the year in Arizona, burned thousands of acres north of Flagstaff. This included the entirety of Sunset Crater Volcano National Monument. More than 700 homeowners were forced to evacuate, and at least 30 structures were destroyed. A state of emergency was also declared.^[2][3]

Background

Further information: List of Arizona wildfires

Historically, while peak fire times were from June to July before monsoon season, wildfires now occur at any time of year. Wildfire conditions are influenced by heavy drought and dryness in the state, but snowmelt in the mountains leads to vegetation growth. With decreasing precipitation in spring, fires tend to start earlier. Monsoons affect fire conditions, with above-average monsoons hindering fires and below-average allowing them to spread. Dryness common in Arizona quickly dries out vegetation, allowing dangerous fire conditions.^[4]

Summary

During the 2021-22 winter, a returning La Niña in parts of Arizona led to potential for an early fire season start from minimal precipitation and snowpack and above-average temperatures. Low moisture in February further reduced the snowpack, exacerbating fire conditions around the state. The La Niña persisted, providing prime wildfire conditions from April to June. They contributed to the Tunnel and Crooks Fires in April, which both lasted until June. Wildfires continued almost "daily" from June to July in Southern Arizona. The Arizona Department of Forestry and Fire Management (DFFM) and other local and federal agencies overloaded resources, allowing most fires to be managed under Type 3 or local suppression strategies.^[5]

Monsoon season began in July, bringing heavy precipitation and moisture. This essentially put an end to fire season with persistent moisture, but lead to growth of new vegetation. However, in October after monsoon season, warm and dry conditions caused a slight increase in wildfires in Southern Arizona. Overall, wildfire ignitions in fall and winter were minimal.^[5]

Overall, acreage and wildfire count was below average and significantly less than 2021, possibly because of heavy suppression operations and a lack of wildfire ignitions in areas dense with fuel.^[5]
