Fast-moving California wildfire claims 'significant' number of buildings

It went from a sparkto a wildfire covering more than 70 square kilometres in about six hours, and officials say the out-of-control blaze in Northern Californiais still growing.

Tens of thousands of people were ordered to flee thefast-moving flames dubbedthe Camp Fire by officials that exploded in size Thursday morning, threatening several communities and forcing panicked residents to race to help neighbours who had to drive through walls of flames to escape.

"Pretty much the community of Paradise is destroyed, it's that kind of devastation," said Cal Fire Capt. Scott McLean late Thursday. "The wind that was predicted came and just wiped it out."

McLean estimated that a couple of thousand structures were destroyed in the town of 27,000 residents about 300 kilometresnortheast of San Francisco, was ordered to get out.By nightfall on Thursday, it had consumed more than 73 square kilometres and firefighters had no containment on the blaze, McLean said.

"We have received reports of some fatalities. Those reports have not yet been verified," Butte County Sheriff Kory Honea told a news conference.

Butte CountyFire Chief Darren Read says multiple civilians and two firefighters have been injuredand a significant number of buildings as many as several hundred have been lost.

An Associated Pressphotographer found businesses and homes levelled or in flames, including a liquor store and gas station.

Acting California Gov. Gavin Newsom has declared a state of emergency in the area.

Evacuees tweeted dramatic videos of what they were forced to drive through.

"It's bad," Honea told the Enterprise-Record. "We're trying to get as many people out as quickly as possible and save as many lives as we can."

"The whole town is burning," Bob Van Camp, a resident who escaped on his motorbike, told local TV channel Action News Now. "We had to ride through flames to get here," he said from the side of a road west of Paradise.

The California Department of Forestry and Fire Protectiontweeted that thefire broke out at about 6:30 a.m. local time in the Feather River Canyon, prompting an evacuation of the immediate area.Just hours later, as the fire spread, officials orderedthe Paradise evacuation.

One woman who got outsaidpeople abandoned their vehicles and held babies and pets as they escaped.

Gina Oviedo said there was fire everywhere as she got out of Paradise, adding that homes were engulfed in flames and utility poles were crashing down.

Paradise resident Kevin Winsteadsaid the whole lower side of the townwas burning."Not one home will be left standing," he said.

Firefighters are struggling with hot, dry conditions and winds of up to 80 kilometres an hour.

"It's really dry and we have low humidity and unfortunately those are great conditions for a fire to spread," saidCal Fire spokesman Rick Carhart.

Carhart said officials were sending as many crews as they could gather.

"Every engine that we could put on the fire, is on the fire right now and more are coming," he said. "There are dozens of strike teams that we're bringing in from all parts of the state."

Shary Bernacett said she and her husband tried to get people to leave the mobile home park they manage in Paradise, with just minutes to evacuate, as thewildfire approached the east side of town.

Bernacett said they "knocked on doors, yelled and screamed" to alert as many of the residents of 53 mobile homes and recreational vehicles as possible to leave the area Thursday morning.

She and her husband grabbed their dog, jumped in their pickup truck and drove through three-metre-high flames before getting to safety.She saidthe air is black with smoke and ash.

Bernacett saidthe fire also overtook the hospitalthree kilometres east of the mobile home park.Adventist Health Feather River tweeted that it has managed to move all of its patientsto other hospitals in the surrounding area.

Shelley Freeman says her family and friends scrambled to get away as thefire approached.

She says she heard from a friend that people, horses and dogs had congregated in a parking lot of a Kmart in Paradise.
