Tens of thousands of people were forced to flee their homes as a deadly brush fire in the Pacific Palisades grew to more than 20,000 acres this week and destroyed thousands of structures.

The Palisades fire grew to 21,596 acres overnight, with evacuations expanding rapidly in Encino, Tarzana and Brentwood as flames threatened homes in Mandeville Canyon. Six helicopters flew throughout the night, dropping water on the blaze as it entered its 5th day Saturday. Containment grew from 8% to 11% overnight, according to Cal Fire.

The Palisades fire can now be seen across Los Angeles' San Fernando Valley, an unsettling development as officials worried about the fire expanding into neighborhoods in Encino and Brentwood and possibly jumping the 405 freeway into Bel Air.
