A significant winter storm has descended upon California, particularly affecting the Sierra Nevada region. Over the weekend, snowfall reached alarming levels with reports indicating up to 28 inches in just one day. Predictions suggest that some areas could see up to 8 feet of snow in total, leading to major travel impacts. The storm has forced closures of major routes including I-80 and US-50, with authorities advising skiers to stay off the roads due to hazardous conditions. Additionally, heavy rain and high winds have compounded risks across Northern California, resulting in flooding in several areas. The storm has been described as the worst in three years, prompting winter storm warnings and alerts for additional precipitation expected in the days ahead. Ski resorts in the Tahoe area reported substantial snowfall accumulation, creating fresh tracks for skiers but also leading to temporary closures as conditions deteriorate.
