The firefighters died in a plane crash Saturday while conducting aerial reconnaissance over the Cedar Basin Fire near the Prescott National Forest, according to a statement issued by the Arizona Bureau of Land Management.

“Our hearts are heavy tonight with sincere condolences to families, loved ones and firefighters affected by this tragic aviation accident that occurred today in Arizona on the #CedarBasinFire,” the agency tweeted.

The lightning-caused Cedar Basin Fire has burned 300 acres.

Meanwhile, southern Oregon’s Bootleg Fire continued to spread exponentially, scorching nearly 144,000 acres in the Fremont-Winema National Forest with 0% containment by Sunday evening, KTVZ reported.

According to energy officials, the Bootleg Fire has already cost California thousands of megawatts of imported power by interrupting three electrical lines that transmit power from Oregon to California, all while the latter struggles to maintain operating reserves as triple-digit temperatures leave portions of the state sweltering, the TV station reported.

The more pressing concern for California, however, remains the Beckwourth Complex Fire that has scorched more than 86 square miles, making it the state’s largest blaze of the current wildfire season, NBC News reported.

The northern California blaze doubled in size between Friday and Saturday, destroying homes in multiple communities, but no official figures or damage assessments have been released, Lisa Cox, public information officer for the Beckwourth Complex Fire, told the Los Angeles Times.

The Beckwourth Complex Fire actually encompasses two lightning-caused fires: the Sugar Fire, which ignited July 2 and remained only 8% contained Sunday after burning more than 83,000 acres, and the Dotta Fire, which started June 30 and had been 99% contained by Sunday morning after burning 670 acres, the Times reported.

“We’re looking at unprecedented early fire season [and] extreme fire behavior,” incident commander Rocky Opliger said during a community meeting Saturday, NBC News reported.
