Shaver Lake, CA – Mountaineers and travelers in the high Sierra Nevada face life-threatening conditions as a major winter storm hammers the range with up to 30 inches of snow through 11 p.m. Sunday. The heaviest impacts are concentrated above 7,000 feet, where a combination of massive snowfall and 55 mph wind gusts is creating extreme whiteout conditions, making travel across the high passes nearly impossible.
According to the National Weather Service in Hanford, a Winter Storm Warning remains in effect for Yosemite, Kings Canyon, and Sequoia National Parks, as well as the Upper San Joaquin River region. Forecasters expect a wide range of accumulation, with a low-end total of 10 inches and a high-end potential of 30 inches in Madera and Mariposa Counties. The sheer volume of snow, coupled with high winds, is expected to reduce visibility to less than one-quarter mile at times through Sunday night.
The storm is severely impacting high-elevation destinations including Lodgepole, Giant Forest, Tuolumne Meadows, and Huntington Lake. Caltrans and local authorities strongly advise against any non-essential travel into the high Sierra. Those who must travel are urged to carry tire chains and a winter survival kit, as road closures can occur with little to no notice. Infrastructure in these remote areas, including power lines and communication towers, remains at risk due to the weight of the snow and the intensity of the wind gusts.
Safety officials emphasize that braking and acceleration should be handled with extreme caution, particularly on the steep inclines near Lake Thomas Edison and Florence Lake. Drivers should ensure their vehicles are fully winterized before attempting any mountain routes. The hazardous conditions are expected to persist until the storm system finally exits the region late Sunday night, though lingering travel delays are likely into Monday morning.
