Late-Season Winter Storm Targets Sierra Nevada With Heavy Snow

Late-Season Winter Storm Targets Sierra Nevada With Heavy Snow...

An unseasonal winter storm is bearing down on California's Sierra Nevada mountains today, prompting the National Weather Service to issue winter storm warnings through Sunday. The system could drop up to 3 feet of snow above 7,000 feet elevation, with the heaviest accumulation expected tonight through Saturday morning.

Meteorologists say this April storm is unusually strong for this time of year, with snow levels potentially dipping as low as 5,000 feet. The weather service warns that travel over mountain passes including Donner Summit and Echo Summit will become "extremely difficult to impossible" during the peak snowfall periods.

Local utilities are preparing for possible power outages, while Caltrans has snowplow crews on standby. The storm comes just weeks after California's snowpack measurements showed below-average levels, making this late-season snowfall particularly surprising.

Ski resorts like Palisades Tahoe and Mammoth Mountain, which had begun scaling back operations for the season, may extend operations if the storm delivers as forecast. The weather system is also expected to bring gusty winds up to 50 mph and colder temperatures across Northern California.

Residents and travelers are being advised to prepare for winter driving conditions and possible chain requirements on major highways including I-80 and US-50. The storm's timing during spring break travel has raised concerns about potential disruptions for vacationers returning from Lake Tahoe area resorts.

This weather event is trending nationally due to its unusual timing and potential impacts on California's water supply. The Sierra snowpack provides about 30% of the state's water needs, making any late-season accumulation significant for drought monitoring.
