Avalanche Summary

No avalanches have been reported.

Snowpack Summary

Alpine areas near Squamish are expected to have the most snow, with around 60 cm or so 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.

Problems

Wind Slabs

Expect wind-loaded pockets of drifted snow behind ridges and peaks in exposed areas.

Use caution in lee areas. Recent wind loading have created wind slabs.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.

Aspects: North, North East, East, South East, North West.
