A tornado near a mall in central California swept up cars, uprooted trees and sent several people to the hospital.
In San Francisco, authorities issued the first-ever tornado warning.
Elsewhere, inclement weather plagued areas of the U.S., with dangerous conditions including heavy snow in upstate New York, a major ice storm in Midwest states and severe weather warnings around Lake Tahoe.
The ice storm beginning Friday evening created treacherous driving conditions across Iowa and eastern Nebraska Friday and into Saturday and prompted temporary closures of Interstate 80 after numerous cars and trucks slid off the road. In upstate New York, more than 33 inches (84 centimeters) was reported near Orchard Park, which is often a landing point for lake-effect snow.
The tornado overturned cars and toppled trees and utility poles, the National Weather Service said. The Scotts Valley Police Department said several people were injured and taken to hospitals.
In San Francisco, some trees toppled onto cars and streets and damaged roofs. Thedamage was due to 129-kph straight-line winds, not a tornado.
The fast-moving storm prompted warnings for residents to take shelter, but few people have basements in the area.
More than 30 centimeters of snow fell at some Lake Tahoe ski resorts, and 181-kph gust of wind was recorded at the Mammoth Mountain resort south of Yosemite National Park, according to the weather service’s office in Reno, Nevada. Up to 90 centimeters of snow was forecast for the Sierra Nevada mountaintops.
