A powerful late-season winter storm is expected to hit the Sierra Nevada, bringing heavy snow and windy conditions through Tuesday. Travel conditions are rapidly becoming hazardous on major routes like I-80 over Donner Pass and Highway 50.
The storm is anticipated to deliver up to 4 feet of snow on the tallest peaks. Wind gusts may reach 70 MPH along the Sierra crest, with localized gusts potentially hitting 80 MPH.
Snow levels are forecast to drop from around 7,000 feet to as low as 4,500 feet. Authorities have indicated that chain requirements will likely begin for most vehicles at elevations above 5,000 feet.
The most dangerous period of the storm is expected from Sunday night through Tuesday morning. Meteorologists warn that snowfall totals could reach up to four feet at higher elevations, leading to considerable visibility problems during the heaviest snowfall periods.
Key impacts:
- I-80 and Highway 50 face multi-hour closures from Sunday night into Monday.
- Blizzard conditions are expected with heavy snowfall of 1-2 feet above 6,000 feet.
- The National Weather Service advises travelers to keep an extra flashlight, food, and water in their vehicles.
This winter storm is not typical for May and could pose serious risks for unprepared drivers. Officials stress the importance of winter preparedness during this unusual weather event.
