10-20 cm of new snow with strong wind will form reactive wind slabs in open terrain.
If triggered the wind slabs may step down to deeper layers resulting in large avalanches.Be aware of the potential for wide propagations due to the presence of hard windslabs.Use ridges or ribs to avoid pockets of wind loaded snow.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
LikelihoodLikely - Possible
Expected Size1 - 2
Deep Persistent Slabs
The weak snow in the lower snowpack could produce large avalanches. Be cautions in areas where the surface feels stiff or slabby, such as around thick wind deposits.
Back off if you encounter signs of instability like whumphing, shooting cracks or recent avalanches.Use conservative route selection, choose moderate angled and supported terrain with low consequence.Avoid shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: All elevations.
