Avalanche Canada
15 to 30 cm of recent snow and southwest wind formed wind slabs in specific locations below alpine ridgecrests.
Use caution when approaching steep and rocky terrain.
Summary
Confidence
Avalanche Summary
A few rider triggered wind slab avalanches up to size 1.5 were reported on north and east aspects in the alpine on Friday.
Snowpack Summary
Strong solar radiation has formed a surface crust everywhere except north facing terrian at upper elevations.
15 to 30 cm of recent snow overlies a crust on all but north facing aspects at treeline and above where a weak layer of surface hoar may be present.
A widespread crust with facets above is down 60 to 110 cm. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places to trigger this layer.
Weak facets at the base of the snowpack remain a concern in steep, rocky alpine terrain with a shallow or thin to thick snowpack.

Terrain and Travel Advice
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- If triggered loose wet avalanches may step down to deeper layers resulting in larger avalanches.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Cornice failure may trigger large avalanches.
Problems
Wind Slabs
15 to 30 cm of recent snow and southwest wind formed wind slabs in specific locations below alpine ridgecrests.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
Likelihood
Expected Size
Persistent Slabs
A crust with weak facets above is down 40 to 110 cm. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the most likely places to trigger this layer.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Expect the sunshine to trigger wet loose avalanches on sunny aspects at all elevations.
Aspects: North East, East, South East, South, South West, West, North West.
