In sintesi

Buried weak layers remain rider-triggerable.

Use extra caution on north-facing slopes at ridgeline.

    Small amounts of new snow over several days and steady winds continue to promote thin wind slab formation in lee terrain.

    A buried weak layer of facets and/or surface hoar buried mid-February exists 50 to 80 cm below the snow surface.

Avalanche Summary

There has been no new avalanche activity reported in the previous few days. If you do observe an avalanche, consider posting a MIN.

Snowpack Summary

10-30 cm of recent new snow has buried widespread layer of surface hoar crystals, which sit over a crust on solar aspects and low elevations.

A layer of facets, surface hoar and/or a crust buried mid February is 30 to 50 cm below the snow surface and has been reactive in snowpack tests.

Deeper in the snowpack, a weak layer of facets and a crust from early December can be found. This layer appears to be dormant but is still worth keeping in mind in thin snowpack areas in the alpine.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
