At least 13 people are dead amid “waist-deep” mudslides in Southern California, where heavy rains triggered flooding, say officials.
Some 163 people have been taken to the hospital. Twenty had “storm-related injuries” and four were critically hurt, the BBC News reported on Wednesday. A group of up to 300 people is reportedly trapped in Romero Canyon, east of Santa Barbara. Police said the scene “looked like a World War One battlefield”.


The flooding and mudslides, affecting areas scorched by wildfires last month, have shut down more than 30 miles (48km) of the main coastal highway. Emergency services said a number of people are unaccounted for and they expect the death toll to rise. Thousands fled the deluge and more than 50 rescues have been performed. The hardest hit homes were those that were not in the evacuation zone, officials say. Heavy rain run-off caused mudflow in the community of Montecito, where some homes were knocked from their foundations, said Santa Barbara County Fire Department spokesman Mike Eliason.


Boulders the size of small cars were rolling down hillsides and blocking roads, reports BBC News Los Angeles correspondent James Cook.
Among those taken to safety was a 14-year-old girl who had been trapped for hours in the ruins of her home. The fire department published a picture of the girl encased in mud as she was led to safety. County Fire Captain Dave Zaniboni said that five people were found dead on Tuesday in Montecito and may have been killed as result of the storm. The upmarket neighborhood includes homes owned by celebrities such as actor Rob Lowe and chats show host Ellen DeGeneres.

The US Coast Guard has sent “multiple airships to support rescue operations” and warn the public not to fly drones, otherwise, the flights will force to be grounded. Wildfires in December, including the Thomas Fire, swept through the area burning vegetation that helps prevent flooding and landslides. Thousands of California residents were asked to evacuate on Monday for the second time in two months. In Burbank, where waves of mud swept away vehicles, officials issued a mandatory evacuation order. Several roads are closed due to mudslides and debris, including the major thoroughfare Highway 101. After a wildfire, burned vegetation and charred soil create a water-repellent layer which blocks water absorption and leads to an increased risk of mudslides and floods.
