 Shortly before noon, the fire had been blown up to the top of Hiller Highlands to the west, from where it began its sweep down into the Hiller Highlands development and the southern hills of Berkeley.Burning embers from houses and vegetation were carried ahead of the fire line by torrid winds and started new blazes ahead of the original burn.Within thirty minutes the fire had crossed both Highway 24, an eight-lane freeway, and Highway 13, a four-lane freeway, eventually igniting hundreds of houses in the Forest Park neighborhood on the northwest edge of the Montclair district and in the upper Rockridge neighborhood.
