    Over the past few days, strong winds have produced smaller avalanches that can be triggered in steep, skiable terrain. There is uncertainty about how reactive these will be in the coming days.

Moderate

Avalanche Summary

No new avalanches were observed or reported on Thursday. However, isolated, smaller wind slabs(size 1-1.5) have been reported in high alpine lees over the past few days.

Snowpack Summary

There has been widespread wind effect down into treeline in exposed areas.

Where the wind hasn't had an impact, the surface is a mix of facets and/ or sun crust, depending on your location. Below this, the mid-pack consists primarily of facets.

At the base of the snowpack lies a widespread, weak layer of depth hoar and a crust. It is dormant for now but should not be forgotten.

Snow depths at the treeline range from 60 to 100 cm.

Weather Summary

Winds NW 30-40kmh, no snow and -12 to 15C at treeline on Friday.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
