This photo provided by Matthew Dangerfield shows billowing smoke from the Calabasas, Calif., fire as the clouds passed over the homes of Park Calabasas, Saturday, June 4, 2016. Los Angeles County fire officials now say a brushfire in the Calabasas neighborhood is threatening about 3,000 homes. Capt. Keith Mora tells KCAL-TV that's how many are near the 200-acre blaze that erupted Saturday afternoon northwest of downtown Los Angeles. He says about 200 homes and some 500 people are under mandatory evacuation but the others are strongly urged to leave the area, where flames up to 50 feet high rolled along ridgetops and torched trees right next to million-dollar homes.
