California wildfires force more rescues, power shut-offs

New wildfires ravaged bone-dry California during a scorching Labour Day weekend that ended with the state's largest utility turning off power to 172,000 customers to try to prevent its power lines and other equipment from sparking more fires.

The U.S. Forest Service says 14 firefighters and bulldozer operators were injured Tuesday while battling a fire in central California. One is in critical condition.The Forest Service says the crew has injuries that include burns and smoke inhalation. Three were airlifted to a hospital, including one in critical condition.

California is heading into what traditionally is the teeth of the wildfire season, and has already set a record with more than 8,000square kilometres burned this year. The previous record was set just two years ago and included the deadliest wildfire in state history the Camp Fire that swept through the community of Paradise and killed 85 people.

That fire was started by Pacific Gas & Electric power lines. Liability from billions of dollars in claims from that and other fires forced the utility to seek bankruptcy protection. To guard against new wildfires and new liability, PG&E last year began pre-emptive power shut-offs when conditions are exceptionally dangerous.

That's the situation now in Northern California, where high and dry winds are expected until Wednesday. PG&E received criticism for its handling of planned outages last year. The utility said it has learned from past problems and said that"this year will be making events smaller in size, shorter in length and smarter for customers."

Thousands of firefighters are battling uncontrolled fires on many fronts, forcing emergency rescues and power shutdowns

Two of the three largest fires in state history are burning in the San Francisco Bay Area. More than 14,000 firefighters are battling those fires and about two dozen others around California.

The fire danger also is high in Southern California, where new fires were burning in Los Angeles, San Bernardino and San Diego counties. The U.S. Forest Service on Monday decided to close all eight national forests in the region and to shutter campgrounds statewide.

"The wildfire situation throughout California is dangerous and must be taken seriously," said Randy Moore, regional forester for the Forest Service's Pacific Southwest Region that covers California.

"Existing fires are displaying extreme fire behaviour, new fire starts are likely, weather conditions are worsening, and we simply do not have enough resources to fully fight and contain every fire."

Lynne Tolmachoff, spokespersonfor the California Department of Forestry and Fire Protection, or Cal Fire, said it's "unnerving" to have reached a record for acreage burned when September and October usually are the worst months for fires because vegetation has dried out and high winds are more common.

Rescue choppers pulled another 164 people from the Sierra National Forest through the morning and were working to rescue 17 others, said Gov. Gavin Newsom, who described pilots wearing night-vision goggles to find a place to land.

"It's where training meets the moment, but it always takes the courage, the conviction and the grit of real people doing real work," Newsom said.

On Saturday, National Guard rescuers in two military helicopters airlifted 214 people to safety after flames trapped them in a wooded camping area near Mammoth Pool Reservoir. Two people were seriously injured and were among 12 hospitalized.

Chief Warrant Officer Joseph Rosamond, the pilot of a Chinook helicopter, said visibility was poor and winds increasingly strong during the three flights he made into the fire zone during the operation that started late Saturday and stretched into Sunday.

His crew relied on night-vision goggles to search for a landing spot near a boat launch where flames came within 15.2metresof the aircraft.

The injured, along with women and children, took priority on the first airlift, which he said filled both helicopters to capacity.

California is having the worst wildfire season in its history with more than 800,000 hectares burned so far this year. Adding to the danger is the extremely dry climate and record-breaking heat.

"We started getting information about how many people were out there, how many people to expect, and that number kept growing. So we knew that it was a dire situation," Rosamond said.

In Southern California, crews scrambled to douse several fires that roared to life in searing temperatures, including one that closed mountain roads in Angeles National Forest and forced the evacuation of the historic Mount Wilson Observatory.

Late Monday night, the Los Angeles County Fire Department told residents of Duarte, Bradbury and Monrovia near the forest to get ready for a possible evacuation.

Cal Fire said a blaze in San Bernardino County called the El Dorado Fire started Saturday morning and was caused by a smoke-generating pyrotechnic device used by a couple to reveal their baby's gender.

In eastern San Diego County, a fire destroyed at least 10 structures after burning 41.4square kilometres and prompting evacuations near the remote community of Alpine in the Cleveland National Forest.

California has seen 900 wildfires since Aug. 15, many of them started by an intense series of thousands of lightning strikes in mid-August. There have been eight fire deaths and more than 3,300 structures destroyed.
