Hanford, California – Heavy mountain snow and strong winds are expected to disrupt travel across California’s Upper Sierra beginning late tonight.
According to the National Weather Service in Hanford, a Winter Weather Advisory remains in effect from 10 p.m. Monday through 4 p.m. Wednesday for elevations above 6,000 feet across Grant Grove, Kings Canyon National Park, Sequoia National Park, and the southern end of the Upper Sierra.
Forecasters say total snow accumulations of 12 to 18 inches are likely above 7,000 feet, with 4 to 10 inches possible between 6,000 and 7,000 feet. At the highest elevations, winds may gust as high as 40 to 50 mph, creating blowing snow and significantly reduced visibility.
The advisory area includes mountain communities and recreation areas such as Giant Forest, Grant Grove, Hume Lake, Cedar Grove, Johnsondale, and Lodgepole. Roadways serving these locations — including Highway 180 through Kings Canyon and Highway 198 leading into Sequoia National Park — may become hazardous or impassable during periods of heavy snowfall.
The National Weather Service warns that travel could be very difficult to impossible, particularly during the Tuesday morning and evening commutes. The heaviest snowfall is expected Tuesday evening into early Wednesday morning, when road conditions may deteriorate rapidly.
Officials urge drivers to slow down, carry chains where required, and check current road conditions before traveling. Updated highway information is available by calling 5-1-1 within California.
The storm may affect commuters, seasonal workers, and visitors planning travel through mountain corridors during the first half of the week.
