The best skiing can be found at below treeline elevations. Caution is still needed in shallow snowpack areas in the alpine where it is still possible to trigger the weak basal facet layer.

Summary

Weather Forecast

Remaining cold with the chance of a light flurry tonight and then clear again tomorrow. Warming trend this week with a forecast of snow at the weekend ;)

Snowpack Summary

Super hard mid-pack is providing bridging strength over the weak basal facet layer at tree line and above. Recent settlement below tree line has greatly improved travel. Reasonable ski conditions can be found in sheltered features at tree line and below.

Avalanche Summary

No new avalanches observed today.

Problems

Deep Persistent Slabs

This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain.

Carefully evaluate and use caution around thin snowpack areas.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 3

Wind Slabs

Strong northerly winds have redistributed snow into isolated pockets of wind slab at alpine elevations.

Use caution in lee areas in the alpine. Recent wind loading have created wind slabs.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 2
