Lake Tahoe weather: Moderate snow to start Tuesday; storms could bring over 3 feet

Lake Tahoe could see anywhere from 13-40 inches of snow, depending on temperatures, from a series of storms expected to start Tuesday.

The updated totals from the National Weather Service in Reno hinge on the possibility that some precipitation could fall as rain at lake level. Above 7,000 feet, snow totals could exceed 4 feet from Tuesday through Friday morning.

The weather service has issued a winter weather advisory from 4 p.m. Tuesday through 4 p.m. Wednesday. A winter storm watch will then take effect and last into early Friday morning.

Accumulation of 5-10 inches of snow is possible at lake level Tuesday afternoon through Wednesday afternoon. Higher totals ranging from 10-18 inches are possible west of California Route 89.

The heaviest snowfall is expected to start Wednesday night.

Elevations above 7,000 feet could see anywhere from 2-4 feet of snow Wednesday night through Thursday. Below 7,000 feet, snow totals could range from 8-18 inches. If all the precipitation remains snow, lake level could see 15-30 inches.

Winds as strong as 45 mph at the lake during the storm watch could make travel over mountain passes nearly impossible, the weather service warns.
