Multiple wildfires were burning across California on Monday, threatening communities and forcing people to leave their homes. The state is moving into a time of year when it usually sees its most destructive wildfires.

Such extreme, unpredictable fire behavior, which has become more common over the last decade, makes it much more difficult for crews to fight the blazes.

The Bridge fire burning in the Angeles National Forest since the weekend jumped to 46,727 acres on Tuesday and was still zero percent contained.

Southern California is on fire again. If you're still hankering to go outdoors, try these trails that are far away from the burned areas.

Firefighters are increasing containment of three major wildfires after a drastic change in weather conditions this week in Southern California. The region's three largest fires -- the Bridge, Airport and Line fires -- all started in early September during a stretch of extremely hot days.
