October 2021 precipitation was heavy along the West Coast, though mostly with very high rain/snow lines. The Oct. 24-25 storm
opened Mammoth and Palisades Tahoe (formerly Squaw Valley) on Oct. 29. Substantial snow also accumulated in the Whistler alpine.
November was unusually warm, plus drier than normal in many regions. The Northwest has been stormy but with more rain than snow.
Late November storms have opened over half the terrain at the Banff areas. Revelstoke and Kicking Horse have 5+ foot bases, which
promises good December skiing when they open.
The warm temperatures have delayed snowmaking and postponed some scheduled opening dates in the western US. Delayed opening dates are a red flag for early season skiing. A bad November does not mean a busted ski season, but coverage and open terrain will likely be extremely limited at western US destination resorts until January, particularly in view of predicted continued dry weather for at least a week into December. Grand Targhee, 61% open, and Alta, 50% open on 30 inch bases, are the most likely exceptions. Mammoth has the next most terrain open at 25%, but most western US resorts are under 10% if open at all. Due to the November weather. October snowfall is not included in season totals other than a few places where October was material to early November open terrain.
California: There were small snowfalls in mid-October. A major atmospheric river dumped several inches of rain up to
10,000 feet before dumping 3+ feet of heavy snow Oct. 24-25. On Oct. 29 Mammoth opened 22% of terrain and Palisades Tahoe 13%
but only for 3 days. It's been warm in November with 7-11 inches new snow above 8,000 feet and most snow melting out
lower down. Only Mammoth is open (25%) with 40 inches snowfall on a 6-26 inch base still holding up well at high altitude. No Tahoe areas
preserved or made enough snow to open in November. See Current California Ski Conditions for more details
on Southern California and Mammoth.

Pacific Northwest: The entire month of October was very wet but the rain/snow line was high. November continued the warm
but wet pattern. A solid snowpack of 51 inches accmulated at 6,000 feet at both Whistler and Blackcomb in November. Mt. Baker got
4 feet of snow mid-November but heavy rain reduced its base to 14 inches. All Washington and Oregon areas have postponed opening dates.

Utah: Utah had well above average October snowfall, but it was gradual so no one opened and it melted out below 8,000 feet. November
tied for driest in the 42 years of Alta Collins records at 22 inches. For the Cottonwood areas only a residual base from October is added to
snow totals.
