A powerful late-season winter storm is set to deliver up to 4 feet of snow and winds reaching 70 mph, causing significant travel disruptions across major routes in the Sierra Nevada. This storm, affecting areas like Donner Pass on I-80, is expected to create hazardous travel conditions through Tuesday.
As snow levels drop from 7,000 feet to as low as 4,500 feet, officials warn that travel could become perilous. The National Weather Service has issued a winter storm warning, advising travelers of possible road closures and urging caution.
Key impacts:
- A forecast of up to 4 feet of snow on the tallest peaks.
- Wind gusts may reach 70 mph along the Sierra crest.
- Travel conditions are already hazardous on I-80 over Donner Pass and Highway 50.
- Chain controls for vehicles are expected at elevations above 5,000 feet.
- Visibility will be drastically reduced during heavy snowfall periods.
The Sierra Nevada typically experiences winter weather in early months—May storms like this one are unusual. Travelers are advised to carry emergency kits that include extra food, water, and flashlights. “If you must travel, keep an extra flashlight, food and water in your vehicle,” specialists recommend.
Transportation officials stress the importance of delaying non-essential trips over the Sierra passes until conditions improve. “When they shut down, they shut down. And if I-80 and 50 both go, you’re not sneaking across somewhere else,” said a local driver reflecting on past storms.
This storm is anticipated to impact travel from Sunday night into Monday. With road closures possible with limited warning during rapidly changing conditions—there’s no telling how long some routes might remain impassable. Drivers should plan accordingly and stay updated with Caltrans for current travel advisories.
