New snow and strong SW winds have built slabs in open areas above treeline. These slabs are sitting on the weak, faceted snow that was previously on the surface and as a result can run further than expected when triggered.
Watch for surface cracking and stiffer surface layers of snow.Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: North, North East, East, South East, South, North West.
Elevations: Alpine, Treeline.
LikelihoodLikely - Possible
Expected Size1 - 2.5
Previous cold temperatures created weak, faceted surface snow. In steep terrain, these facets remain easily triggered and can gain enough mass to affect skiers and climbers. Narrow gullies are where this is most concerning.
Be very cautious with gully features.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.
Aspects: All aspects.
Elevations: All elevations.
