A USA Today article said that at least two people were killed in the disaster. It caused mudslides in the town of Camarillo Springs in Ventura County, the report said.
The storm,one of the strongest to hit the West Coast in years, produced hurricane-force winds of 78 mph and one gust of 147 mph in the Sierra.
The report said that in many parts, there were flash flood warnings. Thanks to the storm, most of the roadways in the region have been closed and left residents trapped in their homes. Several homes were damaged by the deluge, report said.
The report says that many residents got stuck in their homes as "large amounts of debris and heavy water flow prevented rescue teams from accessing homes."
Precautionary evacuations brought on by fear of mudslides began in the Los Angeles suburb of Glendora, where the foothills were stripped bare by a major wildfire earlier this year.
