Good skiing can be found in sheltered areas. There are lots of hazards hidden just under the snow surface.

Summary

Confidence

Moderate

Avalanche Summary

  • No new avalanches were observed or reported today.

Snowpack Summary

Wind slabs dominate the alpine and are more sensitive to triggering along lee features, convex rolls along ridges and cross loaded gullies. The height of the snowpack varies significantly and where it is deeper, the snowpack is generally stronger. The October crust is located in the bottom 20cm of the snowpack andt he November crust is not as widespread and is found about 35cm off the ground. Take the time to dig and investigate these layers.

Terrain and Travel Advice

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Avoid steep terrain that is rocky and thin.

Problems

Wind Slabs

An icon showing Wind Slabs

Recent strong winds have loaded lee and cross-loaded terrain. Multiple layers of "laminated" wind slabs are evident in Alpine and Treeline terrain. Reactivity of these different wind slabs is highly variable.

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

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1 - 2.5

Persistent Slabs

An icon showing Persistent Slabs

The Oct and Nov crusts are faceting, which may mean that persistent slabs are more reactive to human triggering. If triggered the surface wind slabs may step down to this layer.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1.5 - 2.5
