Two people in the McKinney Fire’s path were found dead as California's largest wildfire of 2022 burned more than 50,000 acres in Klamath National Forest over the weekend, a sheriff's office said Monday.Fire personnel found two bodies inside a burned vehicle parked in a residential driveway west of the Klamath River community Sunday morning, the Siskiyou County Sheriff’s Office reported. The people were not identified.The uncontrolled McKinney Fire grew to 86 square miles Monday morning, according to U.S. Forest Service’s Klamath National Forest division. The densely forested region in Northern California has experienced a long-term severe drought, according to AccuWeather.UNRELENTING HEAT: Brutal Pacific Northwest heat wave suspected in seven deathsMore than 2,000 people were forced from their homes as the growing wildfire raged west of Yreka City, about 22 miles south of the California-Oregon border.A heavy smoke inversion – when smoke hangs low to the ground – helped limit the fire’s growth Sunday but also kept aircraft mostly grounded, according to the Forest Service.The few brief showers expected to appear over the fire area Monday may not be enough to help firefighters, said AccuWeather meteorologist Brandon Buckingham.“Because of how dry the entire area is, they need a bigger push of moisture to really be able to put a damper on the fire,” Buckingham told USA TODAY. Winds were expected to pick up later Monday afternoon into the evening, he said.The well-above-average temperatures of the past week, climbing into record-challenging triple digits for many of the region’s lower valleys, have only worsened the dry conditions, Buckingham said.“Over the next few days, there is a kind of a westward push of monsoon moisture into California, but unfortunately, they reside along the fringes of that moisture,” Buckingham said.Any afternoon thunderstorm activity this week could feature dry lightning strikes that can spark additional fires, he said.Crews are still investigating the cause of the 0%-contained McKinney Fire, which ignited July 29 and quickly surpassed the Oak Fire as California’s largest of 2022.The 30-square-mile Oak Fire was 67% contained as of Monday, according to the California Department of Forestry and Fire Protection.This article originally appeared on USA TODAY: McKinney Fire: 2 dead as California's largest wildfire of year rages
