Chester, CA – High-elevation travel across the Northern Sierra Nevada and Western Plumas County is becoming nearly impossible as a potent winter storm settles in, bringing up to four feet of snow to the highest peaks through 11 p.m. Sunday. While the storm began at higher elevations, snow levels are expected to plummet to 4,000 feet by Sunday, creating hazardous conditions for mountain communities and weekend travelers.
According to the National Weather Service in Sacramento, a Winter Storm Warning is in effect as snowfall rates are expected to intensify to one to two inches per hour, particularly between Saturday afternoon and Sunday evening. Total accumulations of one to two feet are anticipated above 4,500 feet, while the highest summits could see between three and four feet of fresh powder. These heavy totals will be accompanied by wind gusts reaching 50 mph, which will likely lead to blowing snow and severely restricted visibility.
The primary impact will be felt on major mountain arteries, including the Interstate 80 corridor through Blue Canyon and routes around Quincy and Chester. Caltrans warns that the combination of heavy snowfall and high winds could result in long-term chain requirements or total road closures. Motorists should anticipate significant delays throughout the weekend and are strongly encouraged to check road conditions via the QuickMap app or by dialing 5-1-1 before attempting any mountain transit.
Safety officials advise residents and travelers to remain off mountain roads if possible. If you must travel, keep an emergency kit in your vehicle containing extra food, water, warm clothing, and a flashlight. This storm is a late-season surge that could cause power outages or damage to trees already weakened by previous weather. Conditions are not expected to stabilize until the early hours of Monday morning, and Winter Storm Warnings remain in effect across the West Slope through late Sunday night.
