Avalanche Problems

Wind Slabs

Subsequent to the Jan 4 wind/precip event windslabs are bonding uncharacteristically well to the old surface. These windslabs are between 10 and 25cm deep.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Deep Persistent Slabs

Human triggering is becoming less likely, however, consequences are high and large avalanches are possible. Do not underestimate this layer as it is quite unpredictable. Utilize terrain wisely, rather than trying to outsmart the snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3
