Firefighters are battling to control a series of major fires in the Los Angeles area that have killed five people, ravaged communities from the Pacific Coast to Pasadena and sent thousands of people frantically fleeing their homes. Ferocious winds that drove the flames and led to chaotic evacuations calmed somewhat on Thursday and were not expected to be as powerful during the day. That could allow firefighters to make progress reining in blazes that have hopscotched across the sprawling region, including massive ones in Pacific Palisades and Altadena.
