LOS ANGELES (Reuters) - At least six people died and thousands fled their homes in Southern California on Tuesday as a powerful rainstorm triggered flash floods and mudslides on slopes where a series of intense wildfires burned off protective vegetation last month.
The heavy downpours subsided early Tuesday after prompting evacuation orders for residents along the Pacific coast north of Los Angeles, but forecasters warned of more rain throughout the day. Rainfall totals ranged from 2 inches to 4-1/2 inches (5 to 11 cm) in the area, the National Weather Servicesaid.
At least six people died in the storm and mudslides in Santa Barbara County, the hardest-hit county in the region, incident command spokeswoman Amber Anderson said in a telephone interview. She did not specify the cause of the fatalities, but said they occurred in several locations in Santa Barbara where there were mudslides.
Television personality Ellen DeGeneres, who owns a home in the upscale community of Montecito where mudslides hit on Tuesday, posted a photo on Twitter of a roadway choked with mud and brown water.
"This is not a river," DeGeneres wrote on Twitter. "This is the 101 freeway in my neighborhood right now. Montecito needs your love and support."
The threat of mudslides prompted the county to order 7,000 residents to leave their homes before the rains came and to urge 23,000 others to evacuate voluntarily.
The county set up an evacuation shelter at Santa Barbara City College and also gave residents a place to take their animals. The weather in Southern California was mild this week, so residents who fled their homes did not have to endure the cold snap that has gripped the U.S. Midwest and East Coast in recent weeks.
A neighborhood in Montecito, where mudslides ravaged homes near the city of Santa Barbara, had not been put under mandatory evacuation orders before mud from a creek cascaded toward homes, Anderson said. She could not immediately say whether any of the fatalities were in the area that was not evacuated.
"Mudslides have covered my town. My friends house was completely leveled and everything is gone," local resident Lauren Gibler said on Twitter.
An unknown number of people in the county were unaccounted for, Anderson said, and 25 residents have been injured.
Photos posted by the local fire department showed a teenager covered in black mud being led away from the rubble of a house that had been destroyed by the Montecito mudslide. The girl had been trapped in the home for hours before rescuers came to her aid, the Santa Barbara County Fire Department said on Twitter.
Other pictures showed ankle-deep mud, logs and boulders in residential areas.
Emergency workers, using search dogs and helicopters, have rescued dozens of people stranded in rubble, Anderson said.
Last month's wildfires, the largest in California history, left the area vulnerable to mudslides. The fires burned away grass and shrubs that hold the soil in place and also baked a waxy layer into the earth that prevents water from sinking deeply into the ground.
The overnight rains forced road closures, including a 30-mile (48-km) stretch of U.S. Highway 101, essentially cutting off traffic between Santa Barbara and Ventura counties northwest of Los Angeles. Ventura County escaped with little damage, the county sheriff's office said.
