LAKE ISABELLA, Calif. — A voracious and deadly wildfire in central California has burned 150 homes and the toll may rise, fire officials said Saturday.

The tally rose from 80 homes as firefighters began going through neighborhoods to count houses and mobile homes incinerated by the blaze.

Entire blocks were reduced to rubble, and at least 2,500 homes remained threatened.

Weather conditions that drove the fire through small southern Sierra Nevada communities with terrifying speed remained a worry, with low humidity and 30-mph steady winds forecast,

“That’s something we have to keep an eye on. It could spark another disaster,” Kern County fire Engineer Anthony Romero said.

About 1,100 firefighters battled the flames.

Gov. Jerry Brown declared a state of emergency, freeing up money and resources to fight the fire and to clean up in the aftermath. The Federal Emergency Management Agency also authorized the use of funds for firefighting efforts.

Since it began Thursday, the fire has swept through nearly 56 square miles of parched brush and timber. It moved so quickly that some residents barely had time to escape – and two didn’t.

An elderly couple apparently were overcome by smoke as they tried to flee, county Sheriff Donny Youngblood said. Their bodies were found Friday but their names haven’t been released.

Everett Evans, 45, fled Thursday as the fire came down a mountain with a roar toward his South Lake mobile home.

“When you hear a freight train, it’s time to leave. You could hear it, you could see it, you could smell it,” he said.

The fire tore through small communities of houses and mobile homes that surround the lake – actually a reservoir – and the Kern River, a popular spot for fishing and whitewater rafting. The communities are nestled in foothills of the Sierra Nevada, a mountain range that runs hundreds of miles north and south through eastern California.

Scorching heat and tinder-dry conditions across the West have contributed to massive wildfires in the past week that have destroyed properties and sent residents to seek shelter and hope for the best.

Laura Rogers thought she’d never see her home or her brother’s home again. Instead, she was lucky to find both standing in a neighborhood of mobile homes that was devastated.

“I was sure this place was gone last night,” Rogers said Friday as she gestured at the destruction around her. “I mean look at this, I can’t believe it. It’s like a scary movie.”

The downspout of her brother’s home was melted on the ground, but the structure was intact.

Dozens of other homes were gone, left in piles of charred sheet metal and cinderblock foundations. Scorched tricycles, air conditioners and TV dishes littered the landscape. Burned-out cars sat on tireless rims and leafless trees poked from blackened dirt.
