RENO, Nevada (AP) — Authorities are responding to a 20-car pileup on the outskirts of Reno amid winter snowstorms in northern California and Nevada.

The Washoe County Sheriff’s Office said Sunday that its deputies said the car wrecks took place in the southbound lane of U.S. Route 395 near Lake Tahoe.

Drivers described white-out conditions with poor visibility.

The sheriff’s department used social media posts to urge people to avoid travel and stay home.

The messages included images of white, snow-crusted highways and cloudy skies.

The winter conditions were tied to wet weather along the West Coast.
