Malibu, Calif. — Cooler temperatures, calmer winds and a chance of rainfall in Southern California this week are forecast to help firefighters as they battle a wind-driven blaze in steep, rugged terrain that's driven thousands, including celebrities, from their homes in Malibu.

The beaches are empty in Malibu as a wildfire tears through swaths of the iconic Southern California coastline, consuming homes and vehicles and forcing residents – including legendary actor Dick Van Dyke – to flee their coveted hillside properties.
