Recent winter storms have unleashed unprecedented snowfall across California, particularly in the Sierra Nevada and Tahoe regions, with totals reaching as high as 9.5 feet in some areas. While ski resorts have celebrated the significant snow accumulation, travelers face treacherous conditions. Interstate 80 and Highway 50 have experienced closures, and chain controls are in effect in multiple areas as icy roads and heavy traffic are anticipated. Southern California mountains have also seen heavy snowfall, prompting safety warnings and travel advisories. Emergency officials are urging residents to limit travel, especially through the weekend, as forecasts indicate more storms are on the way, with snowpack levels lagging despite the recent snowfall boost. As conditions worsen with blizzard warnings and high winds, many areas remain under winter storm advisories.
