Driven by Santa Ana winds, a house fire in California’s Orange County spread to nearby brush and exploded to more than 5.5 square miles overnight.
Officials ordered mandatory evacuations for residents of Modjeska, Silverado and Williams canyons and for Foothill Ranch and parts of Portola Hills.
Voluntary evacuation warnings were issued for part of the Lake Forest community and for Borrego Canyon, Baker Ranch, Live Oak Canyon, Trabuco Canyon, Rose Canyon and Valley Vista Way and Meadow Ridge Drive.
More than 240 firefighters were battling the fast-moving blaze known as the Bond Fire, the Orange County Fire Authority tweeted.
