Weather Service Confirms Tornado Touchdown Near Sacramento

LATROBE, Calif. -- The National Weather Service has confirmed that a tornado struck in El Dorado County, damaging a roof, trees and a power pole.

The agency reports that a funnel cloud touched down around 1:17 p.m. Tuesday and reached speeds up to 100 mph -- a relatively minor tornado.

Officials initially weren't sure if it was a tornado, a downburst or straight line winds. They said witness reports were key to determining the source of the heavy winds.

The twister outside the community of Latrobe ripped part of a metal roof off a building, causing about $1,000 in damage. It also moved a heavy, out-of-use water tank.

A small storm packing high winds moved through Northern California on Tuesday, bringing more snow to the Sierra Nevada and forcing the temporary closure of Interstate 80.
