Problems

Wind Slabs

An icon showing Wind Slabs
Moderate to strong Northerly winds are continuing to reverse load lee features and new slabs will bond poorly with cold temperatures. A small windslab could be sufficient trigger for a large basal facet collapse.

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

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 2

Deep Persistent Slabs

An icon showing Deep Persistent Slabs
Large loads (cornice fall) recently triggered full depth avalanches on this layer on wind-loaded slopes in the alpine.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely - Possible

Expected Size

2 - 4

Cornices

An icon showing Cornices
Recent cornice failures caused several avalanches to size 3 on Saturday. Cold temperatures should make cornices temporarily less failure prone.

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

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

1 - 2
