Avalanche Summary
On Thursday, a small naturally triggered wind slab occurred near Panorama and a skier triggered a large (size 2) loose dry avalanche in the Esplanades.
On Wednesday, a small remotely triggered wind slab occurred on a southwest alpine slope. Explosives triggered large cornices which then triggered a slab below. Whumpfing and shooting cracks were observed here.
Looking forward, we expect human triggering of small wind slabs and loose dry avalanches to remain possible.
Snowpack Summary
Exposed terrain in the alpine and treeline is generally wind-affected. In sheltered terrain, 10 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun-exposed slopes and surface hoar on all other aspects. A weak layer of facets from early December is buried 60 to 120 cm. The base of the snowpack consists of a thick crust with facets or depth hoar in many areas.

Terrain and Travel Advice
- Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Problems
Wind Slabs
Rider triggerable pockets of wind slab may still be found in exposed terrain. Carefully evaluate steep lines for wind slabs.
Aspects: All aspects.
Elevations: Alpine.

Expected Size
Loose Dry
Dry loose avalanches are possible in steep terrain where the snow is powdery and unconsolidated. Use appropriate sluff management techniques.
