A spring snowstorm is headed for the Sierra Nevada and Yosemite.
The National Weather Service says more than a foot of snow is possible by Thursday morning in the mountains west of Lake Tahoe and the Yosemite National Park, prompting closure to Glacier Point Road Wednesday.
Park spokeswoman Scott Gediman says the 16-mile road will remain closed until the storms pass and the road can be evaluated for hazards. The park remains open.
A winter storm warning is in effect in California's western Plumas County until 6 a.m. Friday for elevations above 6,000 feet. A second system is expected Saturday.
The service says cold, windy, wet weather is in the forecast for the Reno-Tahoe area through next Tuesday.
The weather pattern is more typical of early March, but the service says May snowfall isn't that unusual.
Over the past century, snow has been recorded at Lake Tahoe in May about half the time.
