As much as 10cm is on the way Tuesday which will do a lot to improve ski quality. The new snow is probably not enough to increase the danger levels, but keep an eye on localized conditions and be mindful of the soon-to-be-buried wind slabs.

Snowpack Summary

2 to 4cm of new snow in the past 24 hours, which is quickly being blown away by the intense wind at ridgetop. The November crust is down 20-30cm at 2100m and below. Above 2200m the crust gradually turns into wind slabs of varying hardness. Recent north winds have loaded southern slopes near ridges. Expect wind slabs on all aspects except where the wind has scoured down to rock.

Terrain and Travel

  • Approach lee and cross-loaded slopes with caution.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.
