A brush fire fanned by winds in the Angeles National Forest has scorched 750 acres and forced 300 people to evacuate. The Williams Canyon fire erupted shortly before five pm yesterday as temperatures soared above 100 degrees. The California Department of Forestry says it threatened about 25 homes in Camp Williams about 30 miles east of Los Angeles. As many as two-thousand campers also were evacuated from nearby San Gabriel Canyon. About 250 firefighters, six helicopters and five air tankers were fighting the blaze. It´s about three miles from an area scorched earlier this month by the Curve Fire, which consumed more than 16,000 acres.
