UPDATE: 3:30 p.m. Saturday:
An avalanche warning has been issued for the Third Creek area of Incline Village, as well as Crystal Bay, according to a 2:51 p.m. Saturday news release from the North Lake Tahoe Fire Protection District.
“The weather forecast for the next 48 hours calls for increased snowfall intensity and strong winds in the region by this evening,” according to the release. “If the storm materializes as predicted, we could see substantial rapid wind loading of new snow and slightly rising temperatures in the Crystal Bay and Third Creek areas.
“There could be enough loading in the start zones by (Sunday) for large natural or human triggered avalanches to be possible. Third Creek and the adjacent South Slope are not expected to produce avalanches that will affect houses or roads, but Crystal Bay homes and upper roads may be at risk by (Sunday) morning.”
Residents in the Crystal Bay and Third Creek areas should exercise caution if accessing the slopes above their homes, officials said.
“Be prepared to stay indoors tomorrow through possibly Monday until this next storm system passes,” according to the district.

The original story from Saturday morning is below.
TAHOE CITY, Calif. — The Placer County Office of Emergency Services issued an emergency alert at 10 a.m. Saturday, encouraging a voluntary evacuation for residents of Alpine Meadows due to the risk of avalanche.
“The advisory is in effect for residents for all areas of the valley, and may become a mandatory evacuation if conditions worsen,” according to a county news release. “An already considerable avalanche danger throughout the Sierra is likely to increase in many places in eastern Placer County as Sunday’s storm moves in.
“If residents choose not to evacuate, they are urged to closely monitor conditions and be prepared to evacuate quickly if they deteriorate.”
According to the Sierra Avalanche Center, avalanche danger is “considerable” Saturday as a major winter storm continues to dump heavy snow throughout the region and figures to intensify Saturday night and most of Sunday.
“Human triggered wind slab and storm avalanches are likely today. Natural avalanches are possible,” according to the center’s Saturday morning alert. “… Some large and destructive avalanches could occur. Dangerous avalanche conditions exist. Carefully evaluate the snowpack and the terrain before committing to any slopes.
“As another strong winter storm impacts the region (Saturday night) through Monday morning, the avalanche danger will increase.”
Today the avalanche danger is: CONSIDERABLE https://t.co/RkUwykKy3P
