Avalanche Summary

No avalanches have been reported.Please submit any observations you have to the Mountain Information Network here.

Snowpack Summary

Alpine areas near Squamish are expected to have the most snow, with around 70 cm of settled snow on the ground. Recent southwesterly winds may have produced deeper drifts of snow behind ridges. At higher elevations, it is possible the recent new snow may rest on top of a crust. In most places below 1500 m there is insufficient snow for avalanches.

Avalanche Problems

Loose Wet

Heavy rain is expected to saturate the snowpack and promote loose wet avalanche activity on Monday. Loose wet avalanches may occur naturally or with a human trigger - especially in steep terrain.

Use caution above cliffs and terrain traps where small avalanches may have severe consequences.Use extra caution around steeper slopes while the snow is moist or wet.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Very Likely - Certain

Expected Size: 1 - 1.5
