One killed in raging California wildfire as residents flee

One person was killed in a rapidly moving wildfire that sent residents fleeing from a northern California city on Friday as homes and businesses burned and power was cut, fire officials said.

A bulldozer operator was killed in the so-called Carr Fire, a blaze in Shasta County that has tripled in size in the last two days to 28,000 acres (11,300 hectares), the state's forestry and fire protection department (Cal Fire) said.

The blaze crossed the Sacramento River and now threatens hundreds of homes on the western fringes of the city of Redding. Cal Fire said it had been ignited by the mechanical failure of a vehicle.

"The fire is moving so fast that law enforcement is doing evacuations as fast as we can. There have been some injuries to civilians and firefighters," California Department of Forestry and Fire Protection spokesman Scott McLean told the Sacramento Bee newspaper.

"It’s way too dynamic and burning quickly."

Local and state fire officials were not available to confirm details of injuries.

Roads out of the city of 90,000 people were jammed with motorists trying to escape the flames, social media postings showed.

Two residents who chose not to leave were 61-year-old Rob Wright and his wife, who planned to fight off flames from approaching their house with a high-powered water hose.

"We were fortunate enough that the wind changed about hours ago and it is pushing the fire back," said Wright, at about 1:15 a.m. local time. "We are just waiting it out ... crossing our fingers and hoping for the best."

More than 1,700 firefighters were battling the blaze, Cal Fire said in an evening advisory.

"Right now they’re doing what they can, they’re trying to make a stand where they can, if possible," McLean said. “It’s extreme. It’s blowing up off and on again."

McLean added that the wildfire was in an area of rolling hills and not in "house-to-house neighborhoods."

Video footage and images posted on social media showed flames engulfing structures as an orange glow lit up the night sky.

Residents were evacuated to a nearby college and elementary school and a local ABC news station stopped covering the fire in order to evacuate. The Mercy Medical Center in Redding evacuated its neonatal intensive care unit, it said in a statement.

Multiple power outages were reported, the city said on its website, adding that the electric utility was shutting off power in its northern areas.

California Governor Jerry Brown declared a state of emergency in Shasta and Riverside Counties on Thursday over the Carr and Cranston fires, which were being supercharged by temperatures above 100 degrees F (37 C), erratic winds and low humidity.

The California Governor’s Office of Emergency Services said it had activated a state operations center to provide assistance to multiple wildfires burning in Northern and Southern California.
