Carefully assess steep lines for wind slab. The best riding will likely be found in sheltered treeline terrain.
Summary
Confidence
Avalanche Summary
No new avalanches have been reported but observation are limited.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Up to 20 cm of recent storm snow has been redistributed in to wind slabs by southerly winds in the alpine and treeline. This new snow rests over a crust on all aspects below 1800 m. The best riding will be found in sheltered treeline terrain.
The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. Reports indicate these are not currently a concern.
Weather Summary
Thursday Night
Mostly cloudy with up to 5 cm of new snow expected, south alpine wind 30 to 50 km/h, freezing level around 1200 m.
Friday
Mostly cloudy with a few centimeters of new snow expected, southwest alpine wind 30 to 50 km/h, freezing level rising to 1900 m.
Saturday

Terrain and Travel Advice
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Closely monitor how the new snow is bonding to the old surface.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
Wind Slabs
Ongoing snowfall and southerly wind will likely keep the wind slab problem active. These slabs will be more reactive where they overlie a crust.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
As the freezing level rises and recent snow over a crust becomes moist , wet loose avalanches will become possible.
Aspects: All aspects.
Elevations: Below Treeline.
