Southern California mudslides wipe out homes, leaving 13 dead Weeks after devastating fires tore through Southern California, heavy rains sent mudslides rolling down hillsides in Santa Barbara County on Tuesday, leaving 13 people dead. The storm uprooted trees and homes, and left mangled cars and abandoned surfboards on the streets. Roads turned into debris-filled rivers and swallowed up communities downstream from where the Thomas Fire burned thousands of acres last month. "It was literally a carpet of mud and debris everywhere, with huge boulders, rocks, down trees, power lines, wrecked cars -- lots of obstacles and challenges for rescue personnel to get to homes," Santa Barbara County Sheriff Bill Brown said. Mud fillled a Burbank street, destroyed two cars and damaged property. Latest developments • Deadly storm: The 13 deaths were reported in Santa Barbara County, authorities said. • More missing: Officials expect the number to go up as they look for the at least two dozen people who are unaccounted for. • Hundreds of calls: The storm hit hard around 3 a.m. and until 6 a.m., sheriff's office dispatchers handled more than 600 phone calls for assistance, Brown said. • Road closed: The 101 Freeway in parts of Montecito and Santa Barbara, will remain closed for at least 48 hours, authorities said Tuesday. • More rain: By Tuesday, more than 5.5 inches of rain had fallen in parts of Ventura County over two days, the National Weather Service said. In Carpinteria, nearly 1 inch fell in just 15 minutes, the agency said.
