MALIBU, Calif. (AP) — Weather conditions are forecast to improve this week in Southern California and aid firefighters in their battle against a wildfire that’s forced up to 20,000 people from their homes. The blaze has grown to more than 6 square miles by Wednesday morning. It was not immediately known how the Franklin Fire started. It tore through part of Malibu, a community of about 10,000 people on the western edge of Los Angeles renowned for its stunning scenery of seaside bluffs and Zuma Beach featured in Hollywood films.
