In sintesi

A widespread natural cycle was observed through the storm this week. We expect natural activity will decrease, however, conditions are now primed for human triggering into the weekend. If you do choose to go out, continue to make conservative terrain choices.

    Several crusts are now buried in our snowpack. The most concerning is the Feb 03 crust which has a sensitive layer of facets above it in many places.

Avalanche Summary

Numerous natural large avalanches observed on road patrol today to size 3. Several of these appear to have failed on persistent weak layers, based on the depth of the crowns.

Snowpack Summary

Up to 50cm of new snow has formed windslabs and storm slabs at all elevations. The Feb 3rd crust is down 50-100cm and has a thin layer of weak facets above it. The lower snowpack is a well-settled crust/facet complex to the ground. Average snowpack depths are between 100 - 175 cm.

Terrain and Travel Advice

  • Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
