Snowpack Summary
A widespread crust caps the snow surface. The exception may be higher elevation north-facing slopes, where there could be roughly 10 cm of snow sitting above crusts. There could be some weak faceted snow forming around these crusts, but avalanches on this layer are unlikely at this point. The lower snowpack is a well consolidated multi-tiered sandwich of crusts and moist snow.
Watch North Shore Rescue's weekly snowpack conditions update from Friday here.
Terrain and Travel
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
- Pay attention to isolated alpine features as well as cross-loaded features at treeline.
Problems
Wind Slabs
It could be possible to trigger isolated slabs on steep slopes at higher elevations (especially those without a surface crust).
Aspects: All aspects.
Elevations: Alpine.
