Backcountry enthusiasts at Lake Tahoe are being cautioned to exercise extreme caution as a significant winter storm approaches, bringing rapidly changing and potentially hazardous conditions to the Sierra Nevada.
The National Weather Service in Reno issued an avalanche watch at 8:52 a.m. on Wednesday, highlighting the potential for high avalanche danger to escalate on Thursday and into the night. This advisory is set to remain in effect until 9 a.m. Thursday.
Meteorologists predict that heavy snowfall, coupled with strong winds, might trigger widespread avalanche activity across the region. There is a concerning risk of large avalanches that could bury or severely injure individuals in backcountry areas, particularly on steep slopes that have been loaded with wind-driven snow.
The NWS emphasizes the key factors contributing to avalanche risks: steep terrain (typically over 30 degrees), an unstable snowpack, and a triggering event like new snowfall, wind, or human activity in the area. Outdoor enthusiasts are urged to recognize warning signs, such as recent avalanche activity, cracking noises in the snow, and audible “whumpfing” sounds.
Those planning to enter backcountry areas are reminded to check current weather advisories and assess terrain carefully. Additionally, carrying essential avalanche safety gear—such as a transceiver, shovel, and probe—is crucial. The survival rates in an avalanche situation significantly decline after approximately 15 minutes, underscoring the importance of being prepared and having partner rescue skills at the ready.
As the Sierra braces for this winter storm, it is vital that all outdoor adventurers prioritize safety and stay informed about conditions to ensure a safe experience on the slopes.
