California’s high-elevation regions are bracing for heavy snowfall this week, with Lassen Volcanic National Park expected to receive up to 5 feet of fresh snow by Wednesday. The National Weather Service (NWS) has issued winter storm warnings across the northern Sierra Nevada, advising travellers to avoid non-essential trips due to hazardous road conditions, whiteout visibility, and the possibility of avalanches in mountainous terrain.
The storm, fueled by a powerful Pacific moisture system, began moving across Northern California late Sunday and is expected to intensify through midweek. Forecasters predict snowfall rates could reach 2-3 inches per hour during the peak periods of the storm, particularly on Monday night and Tuesday. Gusty winds up to 50 mph at higher elevations will contribute to blowing snow and low visibility, making travel treacherous along mountain passes, including parts of Interstate 80 and Highway 36 near Lassen County.
Lassen Volcanic National Park
Nestled in Northern California, Lassen Volcanic National Park is a popular destination for outdoor enthusiasts year-round. However, during extreme weather events, park rangers caution that trails and roads may be impassable. The Manzanita Lake and Southwest entrances are expected to remain closed or have limited access until conditions improve. Visitors are urged to monitor the National Park Service’s website and local weather updates before attempting trips to the area.
Impact Beyond Lassen
The effects of the storm are also expected to be felt in the broader region, with snow accumulation reaching 1-3 feet in areas above 4,000 feet elevation, including Shasta County and the northern Sacramento Valley foothills. Lower elevations could see heavy rainfall, creating potential flood risks in areas with burn scars from recent wildfires.
Authorities recommend travellers carry emergency supplies, including chains, blankets, food, and water if they must drive through snow-prone areas. The California Highway Patrol is on alert, and Caltrans crews are actively working to clear major roads.
As conditions evolve, residents and visitors are advised to stay updated through the NWS and Caltrans road condition reports.
