Avalanche Summary

Nothing noted or reported today. 

Snowpack Summary

Up to 4cm of new snow in the past 24 hours, which is quickly being blown away by the intense wind at ridgetop. There is an obvious crust down 20-30cm in the trees below 2100m. 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.

Avalanche Problems
