Blustery winds still surged through California on Tuesday after downing trees, fanning wildfires and shutting off power to about 21,000 customers in northern and central regions.

Red flag warnings of dangerous fire conditions continued in mountains, valleys, canyons and deserts because of dry, windy weather. Winds of 25 mph with gusts up to 70 mph into early Tuesday evening.

Pacific Gas & Electric shut off power to about 21,000 customers in 20 central and northern California counties to reduce the risk that power lines could be toppled, sparking wildfires.

California is encouraging more use of fire to fight fire, such as when deliberately set burns were recently used to protect giant sequoias from a raging wildfire.

But sometimes what are known as prescribed fires themselves spread out of control, causing their own extensive damage.

A bill that Gov. Gavin Newsom signed into law Wednesday adds legal protections for private landowners and those who manage the blazes by raising the legal standard for seeking wildfire suppression costs from simple negligence to gross negligence.

Such costs can include not only fighting the fire, but related rescues and investigations.

Thousands of people were under evacuation orders Friday and many others were on notice to be ready to flee as a destructive wildfire raged in a drought-stricken forest in California’s far north.

A woman suspected of starting the Fawn Fire was under arrest, authorities said.

The fire in the Mountain Gate area north of the city of Redding covered more than 9 square miles and was 10% contained, according to the California Department of Forestry and Fire Protection, or Cal Fire.

PG&E Corp. told a judge it has put into place new safety measures that would have resulted in power being cut to a utility line suspected of sparking the second-largest wildfire in California history.

The California utility giant said it changed safety settings on its equipment so electricity can be shut off more quickly in the case of a disturbance or fault on certain lines located in high-fire risk areas, according to a court filing submitted Friday. The move was made after the start of the Dixie Fire in July to help reduce the threat of major wildfires in California in light of the extreme drought conditions and dry vegetation, PG&E said.

Several massive blazes have plagued Northern California this year, and now it could be Southern California’s turn.

The Dixie and Caldor fires continue to do damage in Northern California, putting the state at more than 2.2 million acres burned this year, according to CalFire. The Caldor Fire is at 219,267 acres and 68% contained, and the Dixie fire has burned 960,470 acres and is 75% contained.

The state’s wildfire season has been bad enough that California Insurance Commissioner Ricardo Lara issued notices to insurers alerting them to cease non-renewals and cancellations of insurance coverage for communities with wildfire emergencies.

A magnitude 4.1 earthquake rattled a remote area of west-central California on Tuesday, the U.S. Geological Survey confirmed.

The light temblor occurred at 9:09 a.m. and was centered about 13 miles northeast of Soledad.

The epicenter was in mountains east of the Salinas Valley and north of Pinnacles National Park.

Some 14,000 firefighters facing changing weather conditions battled more than a dozen large wildfires across California, including a growing blaze that was slowly pushing toward the Lake Tahoe resort region.

Winds and temperatures were expected to pick up in coming days while humidity drops, adding to the challenges endured by crews working in rugged terrain.

More than 13,500 firefighters were working Monday to contain a dozen large California wildfires that have destroyed hundreds of homes and forced thousands of people to flee to safety.

After an extensive review of fire damage, Gov. Gavin Newsom requested a presidential major disaster declaration for eight counties, Mark Ghilarducci, director of the California Office of Emergency Services, told a briefing near Sacramento.

If approved, the declaration would provide a wide range of assistance including housing, food aid, unemployment and governmental emergency costs, Ghilarducci said.

Smoke from California’s wildfires choked people on the East Coast. Flames wiped out a Gold Rush-era town. The acreage burned would dwarf the state of Rhode Island.

Images of homes engulfed in flames and mountains glowing like lava would make it easy to conclude the Golden State is a charred black landscape.

That’s hardly the case, but the frightening reality is that the worst may be yet to come.
