In sintesi

  

Small wind slabs may remain reactive to human triggers in isolated locations. Use caution when transitioning into wind affected terrain.

     Isolated pockets of wind slabs could be reactive to human triggers.

Confidence

Moderate - Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches were reported in this region on Saturday.

Data in this region is very sparse. Please submit your observations to the Mountain Information Network. 

Snowpack Summary

Recent northerly winds created wind slabs at treeline and above. Up to 30 cm of recent storm snow sits on top of a crust formed in early December. 

Deeper in the snowpack there are couple of crusts that formed in November. No recent avalanche activity has been reported on the November crusts.

Terrain and Travel

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid areas where the snow feels stiff and/or slabby.
