More than a dozen people are missing and at least 17 are known to have died after mudslides in southern California destroyed homes and swept away cars.
Anxious family members awaited word on loved ones on Wednesday as rescue crews searched for those still unaccounted for.
“It’s just waiting and not knowing, and the more I haven’t heard from them — we have to find them,” said Kelly Weimer, whose elderly parents’ home was wrecked by the torrent of mud, trees and boulders that flowed down a fire-scarred mountain and slammed into a coastal town in Santa Barbara early on Tuesday.
The drenching storm that triggered the disaster had cleared out, giving way to sunny skies, as hundreds of searchers carefully combed a landscape strewn with hazards.
"We've got multiple reports of rescuers falling through manholes that were covered with mud, swimming pools that were covered up with mud," said Anthony Buzzerio, a Los Angeles County fire battalion chief. "The mud is acting like a candy shell on ice cream. It's crusty on top but soft underneath, so we're having to be very careful."
Mr Buzzerio led a team of 14 firefighters and six dogs in thick debris. They used long-handled tools to search the muck in the painstaking task.
Teams rescued three people on Wednesday, but they also discovered two more bodies, raising the death count to 17, Santa Barbara County Sheriff Bill Brown said. Thirteen people were missing.
The deluge destroyed 100 houses and damaged 300 others, Santa Barbara County authorities said. Eight commercial properties were destroyed and 20 damaged.
Some 500 firefighters and other rescue workers were searching debris spread across a wide area of Montecito, a wealthy area of about 9,000 people northwest of Los Angeles that is home to celebrities such as Oprah Winfrey, Rob Lowe and Ellen DeGeneres.
Helicopters were used to hoist more than 50 people to safety from roofs, where they scrambled to escape the mud or because debris had blocked roads and left them stranded.
At one point, a Coast Guard helicopter rescued a family of five and their two dogs. Video shot from the hovering chopper showed a house surrounded by muck and debris as a mother, muddy from the waist down, handed her infant to two rescuers on the roof and then got help onto it. She and her newborn were hoisted to safety, followed by the rest of the family.
People in Montecito had counted themselves lucky last month after the biggest wildfire in California history spared the town. But it was the fire that led to the mudslide, by burning away vegetation.
Only an estimated 10 to 15 per cent of residents fled when ordered and much of the damage occurred where evacuations were voluntary.
The flow was so powerful it swept several homes off their foundations, crushed others and wrapped cars around trees. –AP
