South Lake Tahoe is in the midst of another winter storm that has already dumped more than a foot of new snow at South Shore ski resorts.

The National Weather Service in Reno has issued a winter storm warning for the Greater Lake Tahoe Region. It will stay in effect until 4 p.m. Sunday.

Moderate to heavy snow is expected through the morning with snow showers continuing into the afternoon. An additional 4 to 8 inches of snow could accumulate at elevations below 7,000 feet, while the high country could see 6 to 12 inches at elevations above 7,000 feet.

Winds may range between 15 and 25 mph with gusts up to 40 mph. Ridge wind gusts could be as strong as 110 mph. Caltrans reported Sunday morning that unstable snow conditions forced the closure of California Route 89 near Emerald Bay.

This storm comes on the heels of a “pretty phenomenal” measurement of the snowpack water content recorded near Echo Summit Wednesday. The snowpack water content was 185 percent of normal.

This past week, a forecaster with NWS in Reno told the Tribune that more wet weather will likely move into the Sierra in mid-March.
