Reactive slabs are expected as new snow falls over a crust. Highest snowfall amounts are expected in the east.

Choose conservative terrain until storm snow has had time to bond.




Avalanche Summary

We expect avalanche activity to increase on Sunday with cooler temperatures and fresh snowfall.

Snowpack Summary

Up to 30 cm of storm snow is expected to fall by Sunday afternoon in the Crowsnest Pass and eastern terrain, the Lizard range will likely see around 20 cm. This snow accumulates over a crust and may not bond well.

The middle of the snowpack is generally well bonded in the Lizard and Flathead areas. In the Crowsnest Pass and Elkford areas there is a layer of sugary facets that are buried 30-50 cm deep and in some places may sit on a crust. Avalanches on this layer are unlikely, but we continued to monitor it.

The lower snowpack contains a series of crusts and faceted snow that are more prominent in shallow areas in the east and north of this forecast region.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Keep in mind the crust offers an excellent bed surface for avalanches.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
