A terrifying new wildfire burning out of control north of Los Angeles that has already torched 3,400 acres could “go nuclear,” a wildfire expert warned.

The Palisades Fire and the Eaton Fire also remain active. At least 28 people have died as multiple wildfires, fueled by severe drought conditions and strong winds, rage across Southern California. Thousands of firefighters have been battling wildfires across 45 square miles of densely populated Los Angeles County.
