New snow and strong SW winds are building 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.
Use caution in lee areas. Recent wind loading has created wind slabs.Watch for surface cracking and stiffer surface layers of snow.
Aspects: North, North East, East, South East, South, North West.
Elevations: Alpine, Treeline.
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.
Use caution above cliffs and terrain traps where small avalanches may have severe consequences.Be very cautious with gully features.
Aspects: All aspects.
Elevations: All elevations.
