UPDATE: Rain in Reno, snow in the Sierra keep slick roads, closures, and travel impacts across Nevada and California

Snow continues across the Sierra and western Nevada on Friday morning, with rain in Reno and the surrounding valleys.

Drivers should expect slick roads, chain controls, closures, and travel delays as the winter storm impacts northern California and western Nevada into this afternoon.

The National Weather Service in Reno reports:

  • Winter Weather Advisory for Reno, Carson, and Minden remained in effect until 10 a.m. on Friday

  • Winter Storm Warning for the Sierra, northeast California, Greater Tahoe region, and Mono County has been extended until 4 p.m. on Friday

Heaviest snowfall is expected this morning, 5 a.m. to 9 a.m. in Reno and through noon in the Sierra, with lingering snow showers into the afternoon and evening. Significant travel disruptions are expected before conditions improve this weekend.

Chain controls and road conditions

Chain controls remain in effect on key highways:

  • I-80: R-2 in both directions from the Nevada state line to Nyack

  • SR-267: R-2 from Truckee to Kings Beach

  • SR-89: R-2 from Truckee to Tahoe City

Highway closures

  • Mount Rose Highway (SR 431) remains closed between Mt. Rose Ski Tahoe and Fairview Boulevard in Incline Village while crews continue snow and ice removal

  • State Route 89 through Emerald Bay remains closed due to unstable snow conditions

High-profile vehicles, trailers, and permit loads are advised to avoid mountain passes during ongoing snowfall and avalanche control operations.

High wind impacts

High wind warnings are in effect across exposed mountain areas and western Nevada. Motorists may encounter strong crosswinds, particularly on ridges and open stretches, which can affect high-profile vehicles and create blowing snow hazards.

Avalanche and flood concerns

The Sierra Avalanche Center continues to warn of unstable snow conditions in the Greater Lake Tahoe backcountry. Recent snowfall and wind-loading could trigger avalanches; backcountry travel in avalanche terrain is not recommended.

In Lassen County, the Susan River at Susanville continues to be monitored for potential flooding. While conditions are improving, residents are urged to avoid flooded roadways and low-lying areas. Sandbags remain available through the Susanville Fire Department.

Winter driving tips

Authorities continue to stress safe winter driving practices:

Vehicle preparation

  • Tires properly inflated; winter tires recommended

  • Battery, fluids, and windshield wipers checked

  • Fuel tank at least half full

On the road

  • Slow down, increase following distance

  • Avoid sudden braking or turns

  • Be alert for ice, snow, and shaded areas

Emergency preparedness

  • Warm clothing, blankets, food, water, traction materials, and jumper cables

Visibility and pedestrians

  • Clear snow and ice from windows, mirrors, headlights, and the roof

  • Watch for pedestrians walking in roadways where sidewalks are unplowed

Bottom line for travelers

Travel across the Sierra, northern California, and western Nevada remains hazardous on Friday. Motorists are urged to check road conditions frequently, carry chains when required, allow extra travel time, and stay alert for rapidly changing conditions.
