Avalanche Forecast
Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.
Wind sheltered terrain at higher elevations is likely hold the best riding conditions. Watch for changing conditions in the snow surface as you transition through elevation bands.
Confidence
High
Avalanche Summary
There was a report of a size 1.5 wind slab avalanche at treeline on a north aspect in Manning Park on Saturday.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
Wind affected snow can be found at higher elevations, with recent storm totals of 10-20 cm sitting over a crust below 2000 m.
The snowpack below is considered settled. Weaker layers exist but with thick crusts sitting above, triggering avalanches on these layers is unlikely.
Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m.
