Tens of thousands of people were forced to flee their homes as a brush fire in the Pacific Palisades grew to nearly 20,000 acres by Friday.

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.

Evacuation orders went into effect in Los Angeles' Pacific Palisades neighborhood, with multiple homes under immediate threat on Tuesday.
