Avalanche Summary

Small (size 1) rider triggered wind slabs were reported in this region on Monday.

Snowpack Summary

Forecast strong, southerly winds on Wednesday are expected redistribute the 10-15 cm of recent snow into wind slabs on lee features at treeline and above.

30-40 cm of recent snow has buried the early December crust layers. The snowpack is generally well-settled and strong below these layers. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
  • Use ridges or ribs to avoid areas of wind loaded snow.
  • Avoid terrain traps where the consequence of any avalanche could be serious.
