Confidence

Problems

Storm Slabs

recent storm snow and wind deposits settling over a layer of lower density decomposing precipitation particles

Use caution in lee areas. Recent wind loading have created wind slabs.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Possible

Expected Size

1 - 3

Deep Persistent Slabs

Persistent weak layer now buried around 100cm is still failing suddenly in snowpack stability tests a may potentially result in a large avalanche if triggered

Be aware of the potential for wide propagations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

2 - 4
