Avalanche Summary

Small and large (size 2) storm slab avalanches have continued to occur this week near Fernie, both naturally and with explosives, as recently as Saturday.

Snowpack Summary

Expect surface snow to continue to get wet as temperatures rise and the sun comes out.

Roughly 40 to 50 cm of snow from the past week sits over various old surfaces. In some areas, it is slow to bond due to sugary facets.

Near the bottom of the snowpack, there are a series of crusts and facets that are more prominent in shallow areas.

Terrain and Travel Advice

  • Keep in mind that wet avalanches can be destructive due to their high density.
  • Large cornice falls are dangerous on their own.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
