California Winds Move South, May Force New Power Outages Associated Press LOS ANGELES - Hot, dry winds sweeping into Southern California raised concerns that the region's largest utility could widen power shut-offs Friday to prevent its equipment from sparking wildfires, as a new blaze swept through the San Fernando Valley's northern foothills. Southern California Edison turned off electricity to about 20,000 people in Los Angeles, Ventura, San Bernardino and Kern counties but warned that thousands more could lose service as Santa Ana winds gained strength. Winds gusted dangerously as forecast before calming in Northern California, where Pacific Gas & Electric faced hostility and second-guessing over its widespread shut-offs. The fire danger spread to Southern California on Thursday as raging winds moved down the state. A wildfire fueled by Santa Ana winds broke out after 9 p.m. in Los Angeles along the 210 Freeway and jumped the highway. Flames also crossed the 5 Freeway. The highways were closed because of heavy smoke. The so-called Saddleridge fire, which started in Sylmar, had consumed more than 4,600 acres by 3 a.m. Friday, fire officials said. There were no reports of injuries, but authorities ordered mandatory evacuations in the Granada Hills, Porter Ranch and Oakridge Estates neighborhoods. Several homes were seen burning in Granada Hills, and the Los Angeles fire department said an "unknown number" of homes were potentially threatened. A blaze also ripped through a mobile home park in Calimesa, a city about 65 miles (104 kilometers) east of Los Angeles, destroying dozens of residences. The fire started when trash being hauled caught fire and the driver dumped the load aside a road, according to Riverside County officials. An 89-year-old woman, Lois Arvickson, is missing, according to her son. .
