Strong northeast wind on Wednesday has formed new wind slabs in leeward features.
Seek out areas that have been sheltered from the wind and be cautious of areas that are being actively wind loaded.
Buried surface hoar is lurking in the snowpack and can be hard to detect.
Strong northeast wind on Wednesday has formed new wind slabs in leeward features.
Several surface hoar layers are buried 60 to 100 cm deep across the region. Their spatial distribution and reactivity are uncertain, so use extra caution on large, steep slopes.
On Wednesday, the AvCan field team observed a couple of recent size 2 wind slab avalanches in the Onion riding area.
5 cm of snow today will cover a variety of old snow surfaces. Open areas were heavily wind affected, while sheltered terrain still had soft powder.
A rain crust from mid-December extends up to about 1400 m and is now buried by the recent storm snow. A widespread November surface hoar layer lies 60 to 100 cm deep in sheltered treeline areas. While no recent avalanches have involved this layer, some snowpack tests results have been concerning.
