Avalanche Summary
No new avalanches have been reported.
Please share any reports or photos on the Mountain Information Network (MIN).
Snowpack Summary
Up to 30 cm of generally low-density snow sits atop a well-settled, consolidated mid-snowpack.
The lower snowpack consists of firm, compacted snow, with several older melt-freeze crusts scattered throughout.
Treeline snow depths range from roughly 150 to 200 cm around the Coquihalla and 100 to 150 cm around Manning Park.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
- Seek out sheltered terrain where new snow hasn't been affected by wind.
Avalanche Problems
Wind Slabs
Reactive wind slabs may persist at higher elevations, particularly on steep rollovers, around ridgetops, and cross-loaded terrain.
Wind slab formation may occur through the day on Thursday with periods of snow and increasing winds.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
