The Oct 25 crust is 2-4cm thick and down 60 to 80cm with facets above and below it. Hard progressive collapse failures have been observed immediately below this crust.

Avalanche Problems

Deep Persistent Slabs

Assume all skiable slopes have this crust, and assess the strength of the interface before jumping into any committing lines.

Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5

Wind Slabs

Previous winds created created windslabs in lee features yet their development has slowed with current light to calm winds.

If triggered the storm/wind slabs may step down to deeper layers resulting in large avalanches.Use caution in lee areas in the alpine and treeline. Recent storm snow has formed wind slabs.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
