Recent wind has created heightened avalanche conditions on steep, open slopes in both the alpine and treeline.




Avalanche Summary

A few small (size 1 to 1.5), isolated wind slab avalanches were observed in alpine terrain across the region on Wednesday and Thursday.

Snowpack Summary

Strong northeast wind has redistributed 20 cm of recent low-density snow. This snow may bond poorly to underlying layers of surface hoar, faceted snow, and wind-pressed snow.

A prominent crust is found 30 to 50 cm deep. It extends up to 1900 m in the Cariboos and up to 1400 m around Pine Pass. At this point, the only potential concern with this layer is for areas east of Quesnel and Williams Lake, where a layer of small surface hoar has been observed near the crust.

The midpack is reportedly strong and bonded.

Terrain and Travel Advice

  • Use ridges or ribs to avoid areas of wind loaded snow.
  • Investigate the bond of the recent snow before committing to your line.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.


Wind Slabs

An icon showing Wind Slabs

Recent winds formed slabs at and below ridgetops in atypical areas. These slabs could be more reactive on slopes where they overlie a weak layer of surface hoar and/or a crust.

Aspects: All aspects.

Elevations: Alpine, Treeline.
