Avalanche Summary

An avalanche of size 1.5 was observed on a south-east facing slope in the alpine at Mont Albert. It seems to have occurred on Friday or Saturday.

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

We could receive between 20 and 30 cm of new snow overnight, and possibly another 25 cm during the day on Monday. In the alpine and at treeline, this new snow will be deposited either on hard-packed snow or on exposed rock on the western and northern slopes. On the eastern and southern slopes, the new snow will settle on wind slabs that were still reactive before the storm.

The middle of the snowpack is well consolidated. At depth, a layer of well-developed facets is present, particularly in areas where the snowpack is thinner.

Weather Summary

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Don't let storm day fever lure you into consequential terrain.

Avalanche Problems

Storm Slabs

From Sunday evening to Monday evening, up to 50 cm of new snow is expected, accompanied by moderate to strong winds. Mountains do not respond well to sudden changes, and this weather situation will considerably reduce the stability of the snowpack.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Very Likely

Expected Size: 1.5 - 2.5
