Current snow levels were hovering around 5,500 to 6,000 feet in the northeastern part of California, 6,500 to 7,000 in the Tahoe area, and around 7,000 feet in Mono County, the weather service said, falling by the afternoon to around 5,500 to 6,000 feet.
Meanwhile, the Sierra Avalanche Center in Truckee issued a Backcountry Avalanche Warning for the Central Sierra Nevada Mountains between Yuba Pass (Hwy 49) on the north and Ebbetts Pass (Hwy 4) on the south, including the greater Lake Tahoe area through Tuesday morning. This warning did not include ski areas and highways where avalanche mitigation programs exist.
Forecast models were also showing strong thunderstorms forming in the northern San Joaquin Valley, Sacramento Valley, and western Sierra Foothills, which would turn into heavy bursts of snowfall as the storms move into the high Sierra, the weather service said.
Other intermittent periods of light to moderate snowfall were possible across the Sierra Tuesday and Wednesday before quieter conditions prevail for the remainder of the week, the weather service said.
