Yosemite National Park, California – Travel through the Sierra high country could become dangerous within hours as snow and powerful wind gusts begin impacting elevations above 7,000 feet early Tuesday morning.
According to the National Weather Service in Hanford, a Winter Weather Advisory is in effect from 5 a.m. Tuesday through 5 a.m. Wednesday for Yosemite National Park outside the valley and the Upper San Joaquin River region. There is a 75 percent chance of at least 6 inches of snowfall, along with wind gusts reaching up to 55 mph.
Conditions will deteriorate quickly in areas like Tuolumne Meadows, Wawona, and along routes near Devils Postpile and Florence Lake. Blowing snow may reduce visibility to near zero at times, especially during peak wind periods Tuesday afternoon and evening. Roads, bridges, and exposed mountain passes are likely to become slick, with drifting snow creating uneven driving surfaces.
The combination of heavy snow and strong winds raises the risk of falling trees and blocked ճանապարհs, particularly in forested terrain. Travelers should avoid non-essential trips, carry chains, and prepare for sudden closures along higher elevation routes.
Officials urge visitors to check Caltrans road conditions by calling 511 before heading into the mountains. The advisory remains in effect through early Wednesday, and additional alerts may be issued if snowfall rates or wind speeds increase.
