California blazes threaten populated areas

High temperatures is expected to worsen conditions

Authorities battling massive wildfires in large swathes of California issued mandatory evacuation orders and health warnings Friday over the worsening air quality as the flames grew ever closer to populated areas.
The man suspected of starting one of the blazes was due in court, where he faces life in prison if convicted of arson and other charges.

After almost a month of wildfires, the National Weather Service warned that satellite images showed "widespread smoke this morning from the Western US fires drifting northeastward across the northern Rockies into western and central Canada and then southward over the northern Plains."

The Kaibab National Forest service in neighbouring Arizona warned that "wildfires across the West are creating regional haze."

But it was northern California where most air quality alerts were being issued, with warnings of "unhealthy conditions" for "vulnerable" groups such as the very young and old.



The Mendocino Complex, made of two separate blazes, has been declared the most destructive fire in the state's history, authorities said.

Its largest blaze, the Ranch Fire, was only 53 per cent contained compared to 87 per cent for its twin River Fire.

Further north, the Carr Fire was declared 51 per cent under control, after scorching 180,000 acres (73,000 hectares) of land and claiming the lives of three firefighters and five civilians, making it California's third deadliest fire ever.

The man accused of deliberately starting the latest fast-moving blaze refused to leave his cell for his arraignment hearing initially scheduled for Thursday.

Forrest Gordon Clark, 51, stands accused of starting the Holy Fire, which in four days has burned more than 18,000 acres of Cleveland National Forest 60 miles (100 kilometres) north of San Diego. It is still spreading.



Prosecutors say Clark started the fire, which is only five per cent contained, with the intention of causing damage to others and burning a forest. The blaze has razed a dozen properties so far.

He has also been charged with threatening neighbours — one of whom lost his cabin in the fire — and resisting arrest. He faces sentences ranging from 10 years to life imprisonment.

Mike Milligan, the local volunteer fire chief who owns a cabin near Clark's, told The Orange County Register that Clark had long-running feuds with neighbours in the area.

Milligan said that Clark had recently sent him an email warning, "this place will burn."

The head of the Orange County team fighting the Holy Fire said the blaze had started near Clark's cabin in Jim Canyon.

Before his arrest, Clark told a reporter he had nothing to with the fire.

"I was asleep. I had two earplugs in," he told the reporter. "I woke up and my stuff was all on fire," he said. He also claimed he had been threatened by the MS-13 gang.

The blaze has already forced the evacuation of 7,400 homes and more than 21,000 people. Many schools have been forced to close, and more evacuation orders were being issued.

InciWeb, the interagency incident information management system offering updates on more than a dozen fires in the tinder-dry west of the country, said that "steep inaccessible terrain will continue to allow the fire to spread into new areas."

High temperatures were expected to worsen conditions and "increase the likelihood of extreme fire behaviour as well as heat illness issues for the firefighters and the public," it said.

The forest service said: "We continue to actively engage, but cannot get ahead of the fire."

California Governor Jerry Brown has declared a state of emergency for Orange and Riverside counties, where the fire is concentrated.
