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.

A windstorm is threatening to spread a brush fire in the Pacific Palisades neighborhood in southern California and could trigger more fires as evacuations are underway.

Wildfires and brush fires can quickly spread into neighborhoods in large part because flying embers start little fires that then set homes ablaze. In the catastrophic Palisades fire, one of the city's iconic thoroughfares was severely damaged and large swaths of homes were reduced to smoldering rubble.
