The alpine rating is Wind Slabs., the treeline rating is , and the below treeline rating is Known problems include
Watch for wind slabs on steep open slopes.
No recent avalanches have been reported, however a few small wind slab avalanches have been observed in neighbouring parts of the North Rockies over the past few days.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
In the alpine, up to 15 cm of recent snow sits above a variety of old snow surfaces including wind-scoured snow and faceted snow. At treeline and below, the recent snow sits on a widespread crust.
The snowpack is shallow and faceted with multiple crusts. Pockets of deeper snow may be found near ridges, gully features, and established avalanche paths. Average snowpack depths at treeline average between 40 and 80 cm.
Partly cloudy with no precipitation, light winds shifting from northeast to southwest, treeline temperature -22 °C.
Increasing cloud with a trace of snow in the evening, southwest alpine wind 30 km/h, treeline temperature -15 °C.
Cloudy with 5 to 10 cm of snow by the morning and up to 3 cm during the day, southwest alpine wind 30 to 40 km/h, treeline temperature -12 °C.
Cloudy with a trace of snow, southwest alpine wind 30 km/h, treeline temperature -15 °C.

Terrain and Travel Advice
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Avalanche danger is often elevated in alpine gullies where snow has accumulated.
Northeast wind likely created complicated patterns of wind effect, and possibly formed wind slabs on south and east-facing slopes.
Aspects: South East, South, South West, West.
