Tens of thousands have fled their homes as a brush fire in the Pacific Palisades has burned nearly 20,000 acres as of Thursday. Fire crews are actively working to contain the flames and stop any forward progress.

Thousands of residents have been forced to evacuate the Los Angeles area as wildfires continue to tear through the region.

The blaze began shortly after the start of a Santa Ana windstorm that the National Weather service warned could be the strongest to hit Southern California in more than a decade.
