LAGUNA BEACH, Calif. -- Around 1,500 residents in Laguna Beach's Top of the World and Old Top of the World neighborhoods were forced to evacuate Saturday, CBS Los Angeles reports. A wind-driven brush fire burned hundreds of acres and was threatening structures, authorities said.

The Aliso Fire, which was downgraded from 250 acres to 120 acres, was first reported at 1:07 p.m. local time in Wood Canyon behind Soka University, Orange County Fire Authority Capt. Tony Bommarito said.

According to Aliso Viejo city officials, mandatory evacuations began at 5:30 p.m. in Aliso Viejo, affecting nearly 2,000 homes in the area of Wood Canyon and Pacific Park drives. There was word late Saturday that the evacuation order would be lifted at 9 p.m. local time, according to a tweet from city officials.
