Slide slow, homies. Avalanches are unlikely, but early season hazards abundant.
Small wind slabs may be perched in the lee of ridgecrests as a result of strong northeast winds acting on a recent 10-20 cm of loose snow on the surface.
Avalanche activity has tapered to zero over the past few days, although observations are limited. Little more is expected until it snows again.
Small natural avalanches ran during the overnight period on Nov 22 in the Whistler area. A small cornice tab release was also observed to have triggered a small loose snow avalanche.
Explosives control coaxed another small wind slab from steep terrain the following morning.
Depending on aspect/elevation, either a new crust or a new layer of surface hoar can be found on 10-20 cm of faceting low density snow. In exposed areas you're more likely to find wind-stripped surfaces and perhaps a small, stubborn wind slab in lee terrain.
Where it hasn't blown away, the surface snow sits on a supportive melt-freeze crust buried November 21. Below, additional crusts with well-bonded snow may be found in the top 30-50 cm of the snowpack.
Steady coverage in the open starts at about 1100 m. Above about 1600 m, snowpack height ranges from 50-100 cm, increasing with elevation and deepest on the west side of Hwy 99. The base of the snowpack is well consolidated and bonded to the ground and glacial ice.
