Weather Forecast
Mix of sun and cloud on Wednesday with light flurries. Winds will be light to moderate out of the SW aand temps around -6C at 2300m (treeline). Â
Avalanche Summary
Some sluffing in steep terrain especially in places where the new snow is overlying the previous sun crust.Â
Snowpack Summary
10cm fell overnight bringing recent storm snow totals up to 25cm in the alpine. With little winds over the past two days windslab development has been minimal. The new snow sluffs easily where overlying the crust that developed last week on solar aspects and is slowly settling on the polar aspects. Thin weak areas are still places that we are avoiding for fear of awakening the deep basal layers.Â
Terrain and Travel
- Avoid convexities, steep unsupported terrain and rocky outcroppings.
- Be aware of the potential for large avalanches due to the presence of a deep persistent slab.
- Avoid areas with a thin or variable snowpack.
Problems
Wind Slabs
Some buried wind slabs exist in the alpine.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
The deep persistent layer is still a concern, especially in shallow snowpack areas. A large cornice trigger could also be enough to weak up this layer.
Aspects: All aspects.
Elevations: Alpine, Treeline.
