Howling winds, pelting rain and heavy snow pummeled California, toppling trees, flipping big rigs, cutting power to more than a million people and threatening mudslides in fire-scarred areas.
Flights were grounded and highways closed in Northern California on Friday as gusts reached 80 mph (nearly 130 kph) during the second wave of an arctic storm that sent trees crashing onto houses (pictured above), cars and roads. Forecasters expected the storm to dump as much as 10 feet (3 meters) of snow in the Sierra Nevada by Sunday.
Highways from Sacramento to San Francisco were closed because of debris or toppled big rigs blocking lanes, and local roads were flooded. Interstate 80 was closed in the Sierra, the main link between Northern California and Nevada.
"A huge tree, over 100 years old, just fell across the house. It just wrecked the whole thing," said Faye Reed, whose daughter Teenia owns the damaged home north of Sacramento. "They won't be able to live in it. The whole ceiling fell in, and now it's raining inside."
More than a million people in northern and central California were in the dark. Crews worked to restore power, but it could be days before all the lights are on, said Pacific Gas and Electric spokeswoman Darlene Chiu.
In Southern California, authorities in Orange County ordered an estimated 3,000 residents to evacuate homes in four canyons scarred by wildfires and therefore prone to mudslides.
"It's too late once the rain starts. These areas are extremely vulnerable. You're risking your life and your family's life fundamentally by ignoring orders," said Steve Sellers of the governor's Office of Emergency Services.
Flash flood warnings were issued in canyon burn areas in Malibu and in Santa Barbara and Ventura counties. Riverside and San Bernardino counties, east of Los Angeles, deployed swift-water rescue teams as a precaution.
The state opened its emergency operations center Friday morning to coordinate storm response, and Gov. Arnold Schwarzenegger said he had spoken with Homeland Security Secretary Michael Chertoff by phone.
"Preparation is really the heart of this whole thing," Schwarzenegger said after touring the state emergency operation center at the Los Alamitos Joint Training Base.
Homeowners in Southern California stacked sandbags and hay bales around their homes while residents in the low-lying areas of the Central Valley piled sandbags to barricade their homes from streams that forecasters warned might swell.
Also, search teams later Friday located a missing family of three, who were found safe in a popular hiking destination in the Sierra National Forest. Crews found the family with three other people who had apparently gotten trapped in the woods after the storm hit, said Madera County Sheriff's spokeswoman Erica Stuart. All six hikers were in good condition.
Travelers' flight plans were put on hold when airlines delayed or canceled flights in Sacramento and the San Francisco Bay Area. The state Legislature in Sacramento closed offices and sent employees home early.
A wind gust of 125 mph (200 kph) was recorded in the Sierra on Friday afternoon, the National Weather Service said.
