(AP) — California bore down Saturday against the continuing heat and wildfires that have forced the evacuations of hundreds of homes as red-flag warnings of extreme fire danger predicted gusty winds and scorching, dry air. No homes had burned and the fire was heading southward into Angeles National Forest and away from densely populated areas north of it in Santa Clarita, which has about 180,000 residents. Driven by 20 mph winds, the afternoon fire quickly enveloped more than 5 square miles of brush near a freeway, State Route 14. In the steep, rugged canyons near the Central California coast, a fire near Big Sur in Monterey County burned nearly 1 ½ square miles of brush, grass and redwoods.
