A new wildfire that erupted in northern Los Angeles County triggered tens of thousands of evacuation orders and warnings.

Exhausted firefighters battling deadly infernos for weeks are now grappling with two new wildfires torching Southern California.

At least 28 people are believed to be dead and more than a dozen others remain unaccounted for as multiple wildfires rage across Southern California.

As critical fire weather continues to strike in Southern California, crews are also tasked with preparing for a storm expected this weekend that could trigger mudslides in burn scar areas.

Nearly two weeks after the start of two of the most devastating wildfires to hit the Los Angeles area, Southern California is under an extreme fire risk warning again.
