Winds are back in force and will create dangerous conditions in alpine terrain.

Avoid freshly wind-loaded terrain features and be aware of the potential rider-triggered sluffs on steep slopes.




Avalanche Summary

Friday, several skier-triggered avalanches were reported, including a wind slab on a leeward alpine feature and a storm slab on a sheltered slope at treeline. These avalanches (size 1 to 1.5) likely failed on a buried crust.

Snowpack Summary

Up to 20-30 cm of new snow has fallen into the Chic-Chocs in the last week. In the alpine and treeline, these accumulations bond well to a solid underlying crust. Moderate winds, which have been blowing only for the last 48 hours, brought greater accumulation on leeward slopes. Under this snow, a melt-freeze crust overlies 20 cm of denser snow. This crust is only present in solar aspects. Below treeline, the recent snow is still dry and powdery in places. The mid-snowpack is well consolidated, and of increasing density, interspersed with several melt-freeze crusts from the last few weeks.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.


Wind Slabs

An icon showing Wind Slabs

Strong forecasted wind combined with recent accumulations and upcoming storm snow will develop reactive wind slabs on lee alpine features and cross-loaded areas. Rider-triggered avalanches are likely on steep, supported convex terrain. Avoid freshly wind-loaded terrain features.

Aspects: North, North East, East, West, North West.

Elevations: Alpine, Treeline.
