Crews protect homes as California fire burns near Yosemite National Park

JERSEYDALE, Calif.—a destructive wildfire near Yosemite National Park burned out of control through tinderdry forest on Sunday and had grown into one of California’s biggest blazes of the year, forcing thousands of residents to flee remote mountain communities.

Some 2,000 firefighters battled the Oak Fire, along with aircraft and bulldozers, facing tough conditions that include steep terrain, sweltering temperatures and low humidity, according to the California Department of Forestry and Fire Protection, or Cal Fire.

“It’s hot out there again today,” Cal Fire spokesperson Natasha Fouts said Sunday. “And the fuel moisture levels are critically low.”

Crews on the ground protected homes as air tankers dropped retardant on 50-foot (15-meter) flames racing along ridgetops east of the tiny community of Jerseydale.

Light winds blew embers ahead into tree branches “and because it’s so dry, it’s easy for the spot fires to get established and that’s what fuels the growth,” Fouts said.

The fire erupted Friday southwest of the park near the town of Midpines in Mariposa County. Officials described “explosive fire behavior” on Saturday as flames made runs through bone-dry vegetation caused by the worst drought in decades.

By Sunday the blaze had consumed more than 22 square miles (56 square km) of forestland, with no containment, Cal Fire said. The cause was under investigation.

Evacuations were in place for over 6,000 people living across a several-mile span of the sparsely populated area in the Sierra Nevada foothills, though a handful of residents defied the orders and stayed behind, said Adrienne Freeman with the US Forest Service.

“We urge people to evacuate when told,” she said. “This fire is moving very fast.”

Lynda Reynolds-brown and her husband Aubrey awaited news about the fate of their home from an evacuation center at an elementary school. They fled as ash rained down and the fire descended a hill towards their property.

“It just seemed like it was above our house and coming our way really quickly,” Reynolds-brown told KCRA-TV.
