Lake Tahoe, CA/NV – Backcountry travelers around the Greater Lake Tahoe region are being urged to stay off avalanche-prone terrain today as dangerous conditions develop across the Sierra Nevada.
According to the Sierra Avalanche Center, a Backcountry Avalanche Watch is in effect beginning Thursday at 5 a.m., with avalanche danger rated 4 out of 5 (High) for much of the Tahoe backcountry. The alert was shared by the National Weather Service in Reno late Wednesday morning.
Forecasters say heavy snowfall combined with strong winds is creating unstable snowpack conditions capable of triggering widespread avalanche activity, particularly on steep slopes and wind-loaded terrain.
Officials warn that avalanches during this period could be powerful enough to bury or injure people, knock down trees, and carry debris long distances downslope. Travel in avalanche terrain is not recommended, especially for recreation such as backcountry skiing, snowboarding, and snowmobiling.
The watch covers backcountry areas surrounding Lake Tahoe, including terrain across El Dorado and Placer counties in California, as well as Washoe and Douglas counties in Nevada, impacting areas near the Reno–Sparks metro and popular mountain recreation zones.
Avalanche danger is expected to remain elevated through Thursday night, with conditions potentially worsening as additional snow and wind arrive. Officials urge anyone heading into the mountains to check the latest forecasts, carry proper safety equipment, and strongly consider postponing trips until conditions improve.
