Snowpack Summary
Daily, trace amounts of new snow, spread irregularly over the region on old hard slab in the alpine. A thin sun/temperature crust on steep solar aspects at treeline and below. The southern forecast region has a supportive mid-pack. Less supportive and poor bridging over a pronounced basal weaknesses in the north; Whistlers/Portal and Maligne area

Avalanche Problems
Wind Slabs
Wind slabs are widespread in the alpine on lee and cross-loaded features. Triggering has the potential to initiate the deep persistent slab
- Watch for pockets of hard windslab in steep alpine terrain features..
- Assess start zones carefully and use safe travel techniques.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2.5
Deep Persistent Slabs
Skier triggering could occur in shallow snowpack areas or from large loads such a cornice failure. The consequences of triggering would be severe!
- Avoid steep convexities or areas with a thin or variable snowpack.
- Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 1.5 - 3.5
