Warm temperatures, low humidity and withered brush fed a wildfire in the rugged Orange County hills that charred 155 acres Wednesday as crews hustled to stop the spread of the flames. In neighboring Riverside County, firefighters continued to battle the Bogart fire, which grew to more than 2 square miles. The Holy fire started in the early morning just east of Trabuco Canyon in the Cleveland National Forest, according to Orange County Fire Authority Capt. Larry Kurtz. By late Wednesday, the blaze was 5% contained.
