(Headline USA) A fast-moving brush fire near Yosemite National Park exploded in size on July 23 into one of California’s largest wildfires of the year, prompting evacuation orders for thousands of people and shutting off power to more than 2,000 homes and businesses.
The Oak Fire started on July 22 afternoon southwest of the park near the town of Midpines in Mariposa County and by July 23 had grown to nearly 19 square miles, according to the California Department of Forestry and Fire Protection, or Cal Fire.
It erupted as firefighters made progress against an earlier blaze that burned to the edge of a grove of giant sequoias in the southernmost part of Yosemite Park.
Evacuation orders were put in effect on July 23 for over 6,000 people living across a several-mile span in the sparsely populated, rural area, said Daniel Patterson, a spokesman for the Sierra National Forest.
Gov. Gavin Newsom proclaimed a state of emergency for Mariposa County on July 23 due to the effects of the Oak Fire.
More than 400 firefighters were battling the blaze, along with helicopters, other aircraft and bulldozers, facing tough conditions that included hot weather, low humidity and bone-dry vegetation caused by the worst drought in decades, Patterson said.
“Explosive fire behavior is challenging firefighters,” Cal Fire said in a statement on July 23 that described the Oak Fire’s activity as “extreme with frequent runs, spot fires and group torching.”
By July 23 morning, the fire had destroyed 10 residential and commercial structures, damaged five others and was threatening 2,000 more structures, Cal Fire said.
The blaze prompted numerous road closures, including a shutdown of Highway 140 between Carstens Road and Allred Road — blocking one of the main routes into Yosemite.
Scientists have said the weather will continue to be more extreme and wildfires more frequent, destructive and unpredictable.
“The fire is moving quickly. This fire was throwing embers out in front of itself for up to 2 miles yesterday,” Patterson said. “These are exceptional fire conditions.”
The cause of the fire was under investigation.
Pacific Gas & Electric said on its website that more than 2,600 homes and businesses in the area had lost power as of July 22 afternoon and there was no indication when it would be restored.
“PG&E is unable to access the affected equipment,” the utility said.
A shoeless older man attempting to flee the blaze on July 22 crashed his sedan into a ditch in a closed area and was helped by firefighters.
He was safely driven from the area and did not appear to suffer any injuries. Several other residents stayed in their homes on July 22 night as the fire burned nearby.
Meanwhile, firefighters have made significant progress against a wildfire that began in Yosemite National Park and burned into the Sierra National Forest.
The Washburn Fire was 79% contained on July 22 after burning about 7.5 square miles of forest. It was one of the largest fires of the year in California, along with the Lost Lake Fire in Riverside County which was fully contained in June at 9 square miles.
The fire broke out July 7 and forced the closure of the southern entrance to Yosemite and evacuation of the community of Wawona as it burned on the edge of Mariposa Grove, home to hundreds of giant sequoias, the world’s largest trees by volume.
Wawona Road is tentatively set to reopen on Saturday, according to the park website.
