A tornado in Scotts Valley, a small city about 6 miles north of Santa Cruz "threw multiple cars off the road," the city police department said on Facebook, where it posted images of overturned vehicles. The National Weather Service issued a local storm report that confirmed a touchdown in Scotts Valley at 1:40 p.m. Earlier Saturday, the weather service had issued a tornado warning for San Francisco shortly before 6 a.m., but it was canceled after no tornado organized in the area. In the small city of Mill Valley, about 14 miles north of San Francisco, police said floodwaters stranded several vehicles. The weather service office in Reno, Nevada, forecast as much as 20 inches of snow in the Lake Tahoe and Mammoth Lakes areas of California between Friday and Saturday.
