Firefighters working in searing weather struggled to contain a Northern California wildfire that continued to grow Sunday and forced the temporary closure of a major highway, one of several large blazes burning across the U.S. West amid another heat wave that shattered records and strained power grids.
In Arizona, a small plane crashed Saturday during a survey of a wildfire in rural Mohave County, killing both crew members on board. The Beech C-90 aircraft was helping perform reconnaissance over the lightning-caused Cedar Basin Fire, near the tiny community of Wikieup northwest of Phoenix, when it went down around noon.
Officials on Sunday identified the victims as Air Tactical Group Supervisor Jeff Piechura, 62, a retired Tucson-area fire chief who was working for the Coronado National Forest, and Matthew Miller, 48, a pilot with Falcon Executive Aviation contracted by the U.S. Forest Service.
In California, officials asked all residents to reduce power consumption quickly after a major wildfire in southern Oregon knocked out interstate power lines, preventing up to 5,500 megawatts of electricity from flowing south into the state.
The California Independent System Operator, which runs the state’s power grid, said Saturday the Bootleg Fire took three transmission lines off-line, straining electricity supplies as temperatures in the area soared.
“The Bootleg Fire will see the potential for extreme growth today,” the National Weather Service in Medford, Oregon, tweeted Sunday.
Pushed by strong winds, the blaze exploded to 224 square miles as it raced through heavy timber in Oregon’s Fremont-Winema National Forest, near the Klamath County town of Sprague River.
To the southeast, the largest wildfire of the year in California was raging near the border with Nevada. The Beckwourth Complex Fire — a combination of two lightning-caused blazes burning 45 miles north of Lake Tahoe — showed no sign of slowing its rush northeast from the Sierra Nevada forest region after doubling in size.
