Avalanche Forecast
Regions: North Shore, Sasquatch, South Coast, Tetrahedron.
Watch for isolated pockets of stiff wind slab as you transition into exposed terrain.
A surface crust will make for challenging travel conditions, but generally safe avalanche conditions.
Confidence

Avalanche Summary
There are no new avalanches to report in the past few days.
Snowpack Summary
New snow at upper elevations from early in the week has accumulated over a variety of old surfaces including wind slabs in the alpine and a breakable freezing rain crust between 1100 m and 1600 m.
The mid and lower snowpack is well-settled, strong, and consolidated.
Snowpack depths are reaching 250 cm at treeline.

Terrain and Travel Advice
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
Avalanche Problems
Wind Slabs
Recent snowfall at upper elevations combined with shifting winds may have deposited wind slabs on a variety of aspects. Wind slabs are expected to become less reactive with recent cold temperatures.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely
Expected Size: 1 - 2
