A rare May blizzard has prompted a winter storm warning for the Sierra Nevada, threatening major highway closures and significant travel disruptions. The storm is expected to hit on May 3, 2026, bringing dangerously severe conditions for this time of year.
Snowfall totals in the Sierra Nevada could reach between 1 to 2 feet at elevations above 6,000 feet, with the highest peaks potentially receiving up to 4 feet of snow. Wind gusts are forecasted to reach between 50 to 70 mph, and may even hit up to 80 mph in exposed areas.
The National Weather Service has identified Interstate 80 over Donner Pass as particularly vulnerable to closures due to the impending storm. Travel advisories have been issued, urging residents and travelers to postpone non-essential travel until at least Tuesday.
This winter storm warning highlights the unpredictability of weather patterns in mountainous regions, especially during late spring. In Wyoming, a winter storm watch has also been issued for specific mountain areas, where heavy snow is expected to accumulate between 4 to 10 inches, with localized totals reaching up to 16 inches at elevations above 9,000 feet.
The storm is anticipated to move eastward after impacting California, affecting regions in Nevada, Colorado, and New Mexico. Officials recommend that anyone who must travel during these conditions prepare by checking emergency supplies before heading out.
The National Weather Service defines a winter storm watch as indicating a 50% chance of hazardous winter weather occurring. This serves as a critical reminder for those living or traveling through these areas.
A spokesperson emphasized the importance of being prepared: “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 system develops, residents should stay alert for updates and further advisories.
