Avalanche Summary

No recent avalanches have been observed in this region.

Snowpack Summary

Wind slabs are reported as being widespread and reactive at treeline and alpine elevations. Below treeline, recent snow is likely settling and gaining strength.There are a few deeper weaknesses in the snowpack. Professionals are still tracking a layer around 150 to 200 cm deep, composed of sugary faceted grains, feathery surface hoar, and a sun crust. The base of the snowpack may also still be composed of weak faceted grains in parts of the region. The likelihood of triggering these deep weak layers is low and would most likely be triggered by humans in areas where the snowpack is shallow.

Avalanche Problems

Wind Slabs

Some new snow combined with wind has promoted new wind slab development in lee and cross-loaded terrain features.

Cornices may be touchy; stay well-back on ridges and avoid travelling beneath them.Observe signs of instability: whumpfing, hollow sounds, shooting cracks, and recent avalanches.Use extra caution in wind-loaded terrain features.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5
