TRACY  (AP) — A storm blasted the Southwest with powerful wind gusts, snow and rain on Monday, knocking over big rigs on a stretch of Interstate 205 near Tracy, , toppling trees in Las Vegas and causing dust storm warnings in some areas.

It was a gusty prelude to a storm that was forecast to drop more than a foot of snow in mountainous areas of Utah. A foot had already fallen in the upper elevations of the Sierra Nevada, and a 103 mph gust blew across the mountains near Lake Tahoe.

The National Weather Service says rain and snow will linger into Wednesday.

The California Highway Patrol said two drivers suffered minor to moderate injuries after truck accidents near Tracy.

In Utah, the town of Cedar City was blasted by winds that were toppling trees and shorting power lines. There were scattered power outages in the state.

The Salt Lake Tribune reported that a man and his teenage son were safe after two-foot waves capsized their canoe on a reservoir. Both were wearing life jackets.

KGO-TV reports wind also knocked the facade off a Forever 21 store in the San Francisco Bay Area city of Emeryville. No one was hurt, but two vehicles were damaged.
