Residents living in Fullerton, California were evacuated from their houses after a 20-acre brush fire broke out.

It's one of more than a dozen fires which have broken out in California, but firefighters have managed to tamp them down.

Much of Los Angeles and Ventura counties remained under a National Weather Service red flag warning of extreme fire danger through Thursday (October 31) because of bone-dry humidity and chance of winds gusting to 70 mph (112 kph) in the mountains.
