A rare May blizzard is threatening major highway closures and travel chaos in the Sierra Nevada, as a powerful late-season storm is set to impact the region starting on May 3, 2026. Snowfall totals could reach between 1 to 2 feet at elevations above 6,000 feet, with accumulations of up to 4 feet at the highest peaks.
According to documents from the National Weather Service, wind gusts are expected to reach between 50 and 70 mph, potentially escalating to as high as 80 mph in exposed areas. Travel advisories have been issued, urging residents and travelers alike to postpone non-essential travel until at least Tuesday, due to the hazardous conditions anticipated across major highways.
The situation is not isolated to California; a winter storm watch has also been issued for specific mountain regions of Wyoming, where heavy snowfall is projected. Reports indicate that areas above 9,000 feet may see up to 16 inches of snow, while lower elevations could receive between 4 to 10 inches.
This late-season storm exemplifies the unpredictability of weather patterns in mountainous regions, as winter storm warnings can occur even in May. The storm is expected to move eastward into Nevada, Colorado, and New Mexico after impacting California.
Key impacts of the storm:
- Interstate 80 over Donner Pass is highly vulnerable to closures due to heavy snowfall.
- Wind gusts reaching up to 80 mph could exacerbate road conditions.
- Emergency supplies are recommended for those who must travel during this period.
Officials have emphasized that anyone planning to travel should prepare adequately by keeping emergency items in their vehicles. A spokesperson stated, “If you absolutely must travel during a winter storm, check out this list of emergency items to keep in your car so you’re prepared ahead of time.” As this weather system unfolds, authorities will continue monitoring conditions closely.
