Avalanche Summary
The Avalanche Canada field team observed a few size 2 wind slab avalanches last week. While we have no weekend observations, Friday's storm likely formed more wind slabs, which may still be possible for humans or snowmobiles to trigger in the coming days.
Snowpack Summary
Winter arrived abruptly, building most of the snowpack in the past two weeks. Sheltered areas hold up to 100 cm of snow, while windward slopes are scoured, and leeward slopes may have up to 300 cm.
Friday's snowfall was accompanied by strong westerly winds, forming slabs on easterly aspects. With westerly winds persisting, expect more slabs to develop when it snows.
