Winter storm warning
A rare winter storm warning has been issued for the Sierra Nevada as a powerful late-season storm approaches on May 3, 2026. This blizzard threatens major highway closures and travel chaos across the region.
Snowfall totals are expected to reach between 1 to 2 feet at elevations above 6,000 feet, with up to 4 feet forecasted at the highest peaks. Wind gusts may reach between 50 to 70 mph, potentially hitting up to 80 mph in exposed areas. Interstate 80 over Donner Pass is particularly vulnerable to closures.
In addition to California, a winter storm watch has also been issued for specific mountain regions of Wyoming. Heavy snow is expected there as well, with totals ranging from 4 to 10 inches and up to 16 inches above 9,000 feet. The storm will likely move eastward into Nevada, Colorado, and New Mexico after impacting California.
Authorities have issued travel advisories urging residents to postpone non-essential travel until at least Tuesday. The National Weather Service defines a winter storm watch as indicating a 50% chance of a hazardous winter weather event occurring.
Officials recommend that those who must travel during this winter weather prepare by stocking their vehicles with emergency supplies. A spokesperson noted, “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.”
This unusual May blizzard serves as a reminder of the unpredictability of weather patterns in mountainous regions. Winter storms can occur even late in the season, affecting both residents and travelers alike.
