LOS ANGELES (AP) — Bone-dry vegetation fueled three wildfires near Los Angeles amid warnings Friday that the risk of new blazes erupting was high as temperatures spike and humidity levels drop during a statewide heat wave. A huge forest fire that prompted evacuations north of Los Angeles flared up Friday afternoon, sending up an enormous cloud of smoke as it headed toward the California aqueduct in the Antelope Valley. However, no new evacuations were ordered. The fire was just 12% contained and after threatening more than 5,400 homes, it had charred more than 18 square miles of brush and trees. Cooler overnight temperatures helped firefighters increase containment, but the temperature hit 100 degrees Friday in the area and the forecast called for continuing hot, dry weather with dangerous fire conditions because of possible gusty winds.
