A storm is moving in, and most of the snow lands today. Here’s what the forecasts show over the next 3 days. US numbers come from the National Weather Service, Whistler’s come from Open-Meteo, and lift, trail and snow totals are what the resorts report.

Eastern Sierra

Mammoth Mountain is the one place in this group that’s already spinning. The resort reports 3 of 25 lifts and 3 of 181 trails open, with 0 inches in the last 24 hours and 12 inches so far this season. There’s a Winter Storm Warning, and the forecast calls for heavy snow today with 9 to 11 inches. Then it turns mostly sunny for the weekend. SR-203 has a notice posted, so check before you drive.

Next door, June Mountain isn’t open yet. It reports 0 new and 4 inches on the season. Heavy snow today should bring 8 inches, followed by mostly sunny skies. SR-158 also has a notice up.

Tahoe and the central Sierra

None of these resorts are open yet, and all are under a Winter Storm Warning.

  • Kirkwood leads with 10 inches: 9 today in heavy snow, then a chance of light snow Sunday with 1 more.
  • Sierra at Tahoe is looking at 8 inches: 7 today, 1 Saturday and 1 Sunday.
  • Bear Valley also shows 8 inches. Today brings rain and snow with 7, and Sunday adds 1.
