High winds and new snow are keeping the hazard consistent. In addition to our 3 main problems, there may be a loose dry issue tomorrow as the cold new snow sluffs off the harder layers beneath.

Avalanche Summary

A 2.5 loose dry out of steep alpine terrain mid afternoon.

Snowpack Summary

10cm new snow in the last 24 hours with moderate to strong variable winds. Fresh wind slabs on all aspects in alpine terrain, but only east aspects at treeline. Valley bottom has a new widespread crust from yesterday, which will likely be buried by tomorrow. This new crust is also present on solar aspects up to 2300m. Expect new snow to not stick very well at first.

Problems

Wind Slabs

These are widespread, but of particular concern in crossloaded features.

Evaluate unsupported slopes critically.Avoid steep lee and cross-loaded slopes

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

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1.5 - 2.5

Persistent Slabs

This layer's depth varies based on aspect. In lee areas, it could be 40-60 deep.

Avoid steep Southerly aspects.

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

Elevations: Alpine, Treeline.

Likelihood

Likely

Expected Size

1.5 - 2.5

Cornices

Expect these to grow with the new snow and wind. Minimize exposure as you travel beneath, or above them.

Avoid steep slopes below cornices.

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

Elevations: Alpine.

Likelihood

Likely

Expected Size

1 - 2
