Deeply buried weak layers are expected to become active with rising freezing levels.

Choose conservative terrain free of overhead hazards.




Avalanche Summary

While there has been no slab avalanche activity recently, just west of this region where there is more new snow on the snowpack there have been several large (size 3) avalanches.

On Tuesday there were two skier-triggered deep persistent avalanches (size 1.5-2) west of Invermere in shallow areas. Both times there were tracks on the slope and the skier who triggered it was caught, buried, and recovered uninjured. (one partial burial, one full)

Snowpack Summary

Recent snow continues to settle and bond. This new snow is sitting atop old wind-affected snow and weak, sugary facets.

The mid-snowpack is generally made up of faceted snow and various old crusts.

At the base of the snowpack, weak faceted grains and depth hoar are present, particularly in alpine terrain.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.


Deep Persistent Slabs

If triggered, this problem will likely be the full depth of the snowpack and could run below treeline. Avoid shallow, rocky start zones.
