Weather Forecast

The 3cm of snow we got Sunday night has been blown somewhere on this fine windy Monday.  Tuesday is forecasted to bring a mix of sun and cloud with isolated flurries and yes, more moderate westerly winds.

Avalanche Summary

No new activity.

Snowpack Summary

Alpine:  Wind slabs are widespread.  Be alert for triggering in shallow areas.Treeline:  Wind slabs are noticeable and variable in exposed terrain.Below Treeline:  The snow is now weak and faceted but still supportive to skier traffic.

Avalanche Problems

Wind Slabs

Facetting is helping ease this problem at treeline. The alpine on the other hand is still covered in windslabs of varying densities.
Use caution in lee areas. Recent wind loading has created wind slabs.Evaluate unsupported slopes critically.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5

Deep Persistent Slabs

Large triggers are a concern. It's safe to say we're in the "low probability/high consequence" situation. Avoid thin areas.
Be aware of the potential for full depth avalanches due to deeply buried weak layers.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3.5
