A rare May blizzard is threatening major highway closures and travel chaos in the Sierra Nevada. A winter storm warning has been issued due to a powerful late-season storm expected to bring significant snowfall.
Snowfall could reach up to 4 feet in the highest peaks. Wind gusts may reach 70 mph along the Sierra crest, with localized gusts up to 80 mph. Travel conditions are already hazardous on major routes, including Interstate 80 over Donner Pass and Highway 50.
Snow levels are forecasted to drop from 7,000 feet to as low as 4,500 feet. Chain control regulations will be enforced at elevations above 5,000 feet. Officials advise postponing non-essential travel until at least Tuesday.
The storm is expected to move eastward into Nevada, Colorado, and New Mexico after impacting California. Winter conditions can still strike well into spring, especially in high-elevation areas.
Key impacts:
- A winter storm warning is currently active for the Sierra Nevada.
- Snowfall of up to 4 feet is anticipated in higher elevations.
- Wind gusts could reach as high as 80 mph.
Officials stress the importance of being prepared. “If you must travel, keep an extra flashlight, food and water in your vehicle,” they said. The National Weather Service warned that travel may become extremely challenging and tire traction will be reduced during the period of heaviest snow.
