A wintry storm on Thursday was hammering Southern California with rain that triggered mudslides, flooded streets and worsened a "king tide" across the coast.
At Sunset Beach in Orange County, seawater gushed over streets and parking lots, and NBCLosAngeles.com reported one man in his swim trunks even stood outside his home with a fishing rod.
The king tide, an especially high tide that occurs only a few times a year, was also producing some large waves.
In San Diego, dozens of accidents were tied to the storm, NBCSanDiego.com reported, and flooding closed off various roadways, including at least two highway ramps.
In one accident, a mechanic working on a school bus that broke down on a road suffered serious injuries when the bus was hit by a car, pinning the man underneath, the San Diego Union-Tribune reported.
More than an inch of rain fell within three hours in parts of the city.
Swift water rescue teams were deployed to help people stranded in their cars, while mudslides cut off several streets.
This boulder rolled into the garage of a home in Poway, Calif., on Thursday.
Farther inland, a six-foot boulder crashed through part of a home in Poway, where the rain had been heavy.
"I went into the garage and I saw the washing machine on the floor and then I looked over and saw the rock and couldn’t believe it," homeowner JeNielle Rose-Gendelman told NBCSanDiego.com.
"It’s a big mess, and a big boulder, and I don’t know how it’s going to get out," she said through tears.
The highest tides of the rainy season bring the possibility of flooding as water reaches street level in some regions of the state. NBC's Brian Williams reports.
