A powerful late-season winter storm is set to deliver up to 4 feet of snow and wind gusts reaching 70 mph, causing significant travel disruptions across major routes in the Sierra Nevada.
A winter storm warning is in effect until Tuesday. The storm began impacting the region on Sunday night and will continue through Monday.
Travel conditions on major routes, especially I-80 over Donner Pass and Highway 50, are becoming hazardous. Officials warn that Interstate 80 faces a high risk of prolonged closure.
Key impacts of the storm:
- The storm is expected to bring as much as 4 feet of snow on the tallest peaks.
- Wind gusts could reach up to 70 mph along the Sierra crest.
- Snow levels are forecasted to drop from 7,000 feet to as low as 4,500 feet.
Travelers should prepare for challenging conditions. Caltrans plans to enforce chain controls for most vehicles at elevations above 5,000 feet.
Officials advise that road closures can occur with little warning during rapidly changing weather. “If you must travel, keep an extra flashlight, food and water in your vehicle,” specialists recommend.
As heavy snowfall continues, visibility will be drastically reduced. Transportation officials urge travelers to delay non-essential trips until conditions improve.
