LOS ANGELES—Fast-moving wildfires forced evacuation orders for more than 100,000 people and seriously injured two firefighters in Southern California on Monday as powerful winds across the state prompted power to be cut to hundreds of thousands to prevent utility equipment from sparking new blazes.
A smoky fire exploded in size to over 11 square miles (29 square kilometers) after breaking out around dawn in Orange County, south of Los Angeles. Gusts pushed flames along brushy ridges in Silverado Canyon and near houses in the sprawling city of Irvine, home to about 280,000 residents. There was no containment.
