A Northern California wildfire has destroyed hundreds of homes and businesses and forced area residents to flee their lake community, authorities said Sunday.The fast-moving Clayton fire broke out late Saturday afternoon off Highway 29 and Clayton Creek Road, forcing the entire community of Lower Lake — located more than 100 miles north of San Francisco — to evacuate, officials said. Extreme hot weather combined with the dry brush allowed the fire to grow overnight, burning about 1,400 acres and destroying four homes, according to Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection.
