FRESNO, CA – A powerful winter weather system could bring several feet of snow to California's Sierra Nevada beginning Wednesday, November 18, creating potentially dangerous mountain travel conditions through Friday morning.
According to the National Weather Service in Hanford, a Winter Storm Watch has been issued for Sierra Nevada locations above 5,000 feet, beginning at 4 a.m. Wednesday and continuing until 4 a.m. Friday, November 20.
Forecasters expect 12 to 24 inches of snow above 6,000 feet , while elevations exceeding 8,000 feet could receive 48 inches or more . Wind gusts along mountain crests could reach 45 mph, further reducing visibility during periods of heavy snowfall.
The approaching storm could affect mountain communities and travel corridors throughout the central and southern Sierra Nevada, including higher elevations near Shaver Lake, Huntington Lake and Yosemite National Park.
Drivers traveling into mountain areas should prepare for rapidly changing road conditions, especially along highways leading into higher elevations. Snow covered roads, reduced visibility and icy surfaces could make travel difficult or dangerous.
The National Weather Service warns that tire chains may become necessary for motorists traveling through affected mountain routes. Travelers should check current highway conditions and chain requirements before departing.
The most significant impacts are expected between Wednesday morning and Friday morning, when moderate to heavy snowfall could combine with gusty winds.
Residents and visitors planning mountain trips should monitor updated forecasts, carry emergency supplies and allow additional travel time.
A Winter Storm Watch means conditions are favorable for significant winter weather, but exact snowfall amounts and impacts may change as the system approaches.
Additional advisories or warnings could be issued as forecasters gain confidence in the storm's timing and intensity.
