Wildfires began breaking out in Southern California Tuesday morning as a life-threatening, widespread windstorm that could be one of the most destructive to hit the region in over a decade roars to life and creates extremely dangerous fire weather conditions.

Strong winds — with gusts as high as 79 mph in the San Gabriel Mountains — began blowing their way through Southern California on Tuesday morning, Jan. 7, leading to the possibility of downed trees and wires, power outages and dangerous fire weather.

Millions of people across Southern California are under a Red Flag warning as a dangerous windstorm fanned blazes in the Los Angeles area, including the Palisades Fire, which has triggered evacuations and burned hundreds of acres.
