A powerful winter storm is set to hit parts of California’s Sierra Nevada, with officials warning of dangerous conditions that could severely impact travel.
Forecasters have issued a Winter Storm Warning for key routes including Interstate 80 (I-80) and Highway 50, both of which are expected to be heavily affected over the next 36 hours.
The storm is forecast to bring up to 24 inches of snow in higher elevations, with strong winds reaching as high as 75 mph in some areas.
These conditions could lead to whiteout visibility, black ice, and hazardous driving, especially across mountain passes like Donner Summit.
Authorities say chain controls are likely and road closures are possible if conditions worsen, particularly during peak snowfall periods.
The storm system is expected to linger through Tuesday into Wednesday, increasing the risk of prolonged disruptions for drivers.
Officials are also warning that even after snowfall slows, roads may remain dangerous due to ice buildup and lingering snowpack.
Drivers are being urged to avoid unnecessary travel and prepare for rapidly changing conditions if they must be on the road.
The affected highways are some of the most critical routes through the Sierra, meaning delays and disruptions could impact thousands of travelers.
Experts say storms like this can escalate quickly, turning already difficult roads into near-impossible driving conditions within hours.
