Several wind slab avalanches were triggered around treeline elevations on Thursday, all within the recent 10 to 30 cm of storm snow.

Avalanche activity may decrease for Friday, but it still remains possible that humans could trigger recently formed slabs.

We'd appreciate any observations while you are out travelling, even just a photo, on the Mountain Information Network.

Storm and wind slabs have formed from around 30 to 50 cm of recent snow. The storm slabs are likely found in areas sheltered from the wind while wind slabs are likely found in lee terrain features at higher elevations. This snow builds on the 100+ cm of snow that has fallen since January 1, which reports indicate is bonding well to the snowpack.

The middle and base of the snowpack are strong, consisting of well-bonded snow and various hard melt-freeze crusts.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• The new snow may require another day to settle and stabilize.
• Make observations and assess conditions continually as you travel.
