Wildfires raged unchecked throughout California Wednesday, and gusty winds could drive flames into new ferocity, authorities warned.

Diablo winds in the north and Santa Ana winds in the south were forecast into Wednesday at a time when existing wildfires already have grown explosively.

On Tuesday, 14 firefighters were forced to deploy emergency shelters as flames overtook them and destroyed the Nacimiento Station, a fire station in the Los Padres National Forest on the state’s central coast, the U.S. Forest Service said. They suffered from burns and smoke inhalation, and three were flown to a hospital in Fresno, where one was in critical condition.

In the past two days, helicopters were used to rescue hundreds of people stranded in the burning Sierra National Forest, where the Creek Fire has destroyed 365 buildings, including at least 45 homes, and 5,000 structures were threatened, fire officials said.

Flames threatened the foothill community of Auberry between Shaver Lake and Fresno.

In Southern California, fires burned in Los Angeles, San Bernardino and San Diego counties, and the forecast called for the arrival of the region’s notorious Santa Anas. The hot, dry winds could reach 50 mph at times, forecasters said.

People in a half-dozen foothill communities east of Los Angeles were being told to stay alert because of a fire in the Angeles National Forest.

“The combination of gusty winds, very dry air, and dry vegetation will create critical fire danger,” the National Weather Service warned.

The U.S. Forest Service on Monday decided to close all eight national forests in the southern half of the state and shutter campgrounds statewide.

More than 14,000 firefighters are battling fires. Two of the three largest blazes in state history are burning in the San Francisco Bay Area, though they are largely contained after burning three weeks.

California has already set a record with nearly 2.3 million acres (930,800 hectares) burned this year — surpassing a record set just two years ago — and the worst part of the wildfire season is only beginning.

“It’s extraordinary, the challenge that we’ve faced so far this season,” Gov. Gavin Newsom said.

The threat of winds tearing down power lines or hurling debris into them and sparking a wildfire prompted Pacific Gas & Electric, the state’s largest utility, to shut off power to 172,000 customers over the weekend. More outages were expected Wednesday, with power not expected to be completely restored until Wednesday night.

To the south, Southern California Edison warned roughly 55,000 customer accounts may lose power while San Diego Gas & Electric said 16,700 customers are at risk of a preemptive outage.

In the Sierra National Forest east of Fresno, dozens of campers and hikers were stranded at the Vermilion Valley Resort after the only road in — a narrow route snaking along a steep cliff — was closed Sunday because of the Creek Fire.
