New snow and winds will create slabs in exposed areas. As the day progresses, watch for stiff or cracking snow. There is a layer of surface hoar that exists in some locations, dig down to see how new snow is bonding.

Great skiing will be found in sheltered treeline locations.

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed or reported in the past few days.

Snowpack Summary

In sheltered areas, 5 to 10cm of new snow has fallen on top of a surface hoar layer. Below this is roughly 30 cm of soft snow and a generally supportive snowpack. We’re currently tracking a mid-November melt-freeze crust located in the mid-pack, though it has not shown any activity in our profiles.

Terrain and Travel Advice

Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
Wind slabs are most reactive during their formation.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
