LOS ANGELES: Wildfires raged on Sunday (Monday in Manila) across much of California forcing hundreds to evacuate homes as the most populous US state sweltered in record heat. About 5,000 firefighters were battling 14 large wildfires around the state, according to Cal Fire. Among the largest was the Alamo fire near San Luis Obispo County. The fire there had scorched 23,876 acres (100 square kilometers) and was just 15 percent contained, officials said. In neighboring Santa Barbara County about 1,000 firefighters were racing to contain that fire with help from water-dropping helicopters. Meanwhile, a fire in Butte County in the north-central part of the state destroyed 5,600 acres and 17 structures, Cal Fire said. Evacuations were in effect and four injuries have been reported. Most of southern California including metropolitan Los Angeles has been in the grips of a blistering heat wave, with temperatures exceeding 100 degrees (37 degrees Celsius).
