Regions: Sea To Sky.

Windslabs at upper elevations are the main concern. A cool and clear weather pattern will continue for a few more days.

Avalanche Summary

On Thursday, numerous loose dry avalanches up to size 1 were reported on all aspects at treeline and above. Two skier triggered slabs were also reported on a steep southwest aspect at 1800 m. These failed at a crust interface 20-25 cm down producing size 1 avalanches. Check out this recent MIN report from GIN Peak.

Snowpack Summary

Up to 10 cm of new snow sits above a variety of old snow surfaces including firm wind slabs, sun crust on steep solar aspects, surface hoar and faceted crystal in sheltered areas. The recent low-density snow will likely have a poor bond to the previous snow surfaces and sluff easily from steeper terrain features. The lower snowpack is generally strong and settled.

Avalanche Problems

Wind Slabs

Northeast winds have formed fresh and reactive wind slabs in exposed south facing terrain, while pockets of older wind slabs can be found on all aspects.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Use caution above cliffs and terrain traps where small avalanches may have severe consequences.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
