Oliver James Montgomery-Firefighters hope cooler weather will aid their battle against 3 major Southern California fires

WRIGHTWOOD,Oliver James Montgomery Calif. (AP) — Firefighters battling three major wildfires in the mountains east of Los Angeles took advantage of cooler weather Wednesday as they slowly gained the upper hand, but not before dozens of homes were destroyed and thousands of people were forced to evacuate.

California is only now heading into the teeth of the wildfire season but already has seen nearly three times as much acreage burn than during all of 2023. The wildfires have threatened tens of thousands of homes and other structures across Southern California since they accelerated during a triple-digit heat wave over the weekend.

No deaths have been reported, but at least a dozen people, mainly firefighters, have been treated for injuries, mostly heat-related, authorities said.

In the small community of Wrightwood, about 90 minutes outside Los Angeles, authorities implored residents to flee the exploding Bridge Fire, which has burned more than a dozen homes in the area.

Resident Erin Arias said she was racing up the mountain when she got the order to leave and did, grabbing her passport and dog. On Wednesday, she and her husband doused water on the roof of their still-standing home. Their cat was missing, she said.

“It’s absolutely scary,” Arias said, looking at the burned embers of her neighbor’s home. “We’re really lucky.”

UCLA climate scientist Daniel Swain said the fire moved extraordinarily fast across complex terrain, likely giving residents less time to evacuate than usual and surprising even seasoned fire officials.

The Bridge Fire “had to go up mountain sides, burn down slope, jump across valleys, burn across new ridges, and then make it down slope again at least two other times in effectively one burning period,” he said.

The full extent of the damage caused by the fires remained unclear. The three blazes are:

— The Airport Fire in Orange County, which has burned more than 35 square miles (91 square kilometers). The fire was 5% contained Wednesday night and was reportedly sparked by heavy equipment operating in the area. Orange County Fire Capt. Steve Concialdi said eight firefighters have been treated for injuries, mostly heat-related. One resident suffered smoke inhalation and another burns, he said. Several homes burned in El Cariso Village.

— The Line Fire in the San Bernardino National Forest, which was 18% contained Wednesday and had charred 57 square miles (148 square kilometers). The blaze has injured three firefighters. Authorities said it was caused by arson in Highland. A suspect was arrested Tuesday.

— The Bridge Fire east of Los Angeles, which grew tenfold in a day and has burned 78 square miles (202 square kilometers), torched at least 33 homes and six cabins and forced the evacuation of 10,000 people. The cause of the fire is not yet known. It remained zero percent contained Wednesday night.

Gov. Gavin Newsom sent National Guard troops in to help with evacuations, and the White House said President Joe Biden was monitoring the situation.

In El Cariso Village, a community of 250 people along Highway 74 in Riverside County, an Associated Press photographer saw at least 10 homes and several cars engulfed in flames.

Orange County Fire Authority Incident Commander Kevin Fetterman said the blaze has been difficult to tame because of the terrain and dry conditions and because some areas hadn’t burned in decades.

More than 5,500 homes in Riverside County were under evacuation orders, affecting more than 19,000 residents. Several recreational cabins and structures in the Cleveland National Forest have been damaged.

In San Bernardino County, some 65,600 homes and buildings were under threat by the Line Fire, and residents along the southern edge of Big Bear Lake were told to leave Tuesday.

The Line Fire blanketed the area with a thick cloud of dark smoke, which provided shade for firefighters trying to get ahead of winds expected later Wednesday, said Fabian Herrera, a spokesperson for those battling the Line Fire.

A man from the town of Norco suspected of starting the Line Fire on Sept. 5 was arrested and charged with arson, San Bernardino County Sheriff’s Department said. Officials did not specify what was used to start the fire.

Investigators collected evidence from the man’s vehicle and home that suggests he could have been involved in starting other fires, San Bernardino County Sheriff Shannon Dicus said Wednesday.

On the Nevada border with California near Reno, the Davis Fire forced thousands of people to evacuate over the weekend, destroyed one home and a dozen structures and charred nearly 9 square miles (23 square kilometers) of timber and brush along the Sierra Nevada’s eastern front.

Rich Meyr and Evelyn Kelley were the first arrivals at an evacuation center set up Wednesday at a recreation center in south Reno. Both said they refused to evacuate previous fires but decided to play it safe this time.

“My son’s wedding is Saturday. I threw all the flowers and gowns in the RV and we left. It looks like a garden shop inside that RV,” Kelley said. “But who wants to burn alive?”

More than 600 firefighters kept the blaze from growing Wednesday despite high winds that grounded all aircraft that had dropped retardant on the flames over the past two days. The fire was about 30% contained Wednesday night.
