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 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.

The massive Palisades fire has destroyed an estimated 75% of the Pacific Palisades and officials say the 1/3rd of the eastern edge of Malibu has also been destroyed. The fire is now threatening the nearby communities of Brentwood and Encino.
