MONTECITO, Calif. — Anxious family members awaited word on loved ones Wednesday as rescue crews searched grimy debris and ruins for more than a dozen people missing after mudslides in Southern California destroyed an estimated 100 houses, swept cars to the beach, and left at least 17 victims dead.
‘‘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 the coastal town of Montecito in Santa Barbara County early Tuesday.
The drenching storm that triggered the disaster gave way to sunny skies, as hundreds of searchers carefully combed a messy landscape strewn with hazards.
‘‘We've gotten 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.’’
Buzzerio led a team of 14 firefighters and six dogs in deep debris. They used long-handled tools to search the muck in the painstaking task.
Teams rescued three people Wednesday, but they also discovered two more bodies, raising the death count to 17, Santa Barbara County Sheriff Bill Brown said. Seventeen people were reported missing.
A dozen people were hospitalized at Santa Barbara Cottage Hospital and four were in critical condition, Dr. Brett Wilson said.
‘‘Most injuries we saw were related to fast-moving debris,’’ Wilson said. ‘‘You can’t even fathom what these poor patients went through to finally make their way to the emergency department.’’
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 swath of Montecito, a wealthy enclave of about 9,000 people northwest of Los Angeles that is home to such celebrities 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.
