In sintesi

Reactive wind slabs have been catching people by surprise.

Be extra cautious in wind-affected terrain and give cornices a wide berth.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    Wind slabs have been reactive, especially where they overlie a weak surface hoar layer.

  • Cornices

    Cornices remain a concern on Sunday. Avoid travelling on or under large cornices, especially if you see blowing snow.

Confidence

Moderate

  • Uncertainty is due to limitations in the field data.

Avalanche Summary

Saturday:
Skiers accidentally triggered wind slabs on Mt.Fernie (MIN post here) and in Cabin Bowl - see photo.

Friday:
Several size 1 to 2 slab avalanches and cornice falls were reported in the Lizard Range. Some were accidentally triggered by skiers, while others were explosive controlled or natural. They all occurred in the alpine on wind-loaded northerly through easterly slopes.

Looking forward:
We expect wind slabs and cornices to remain triggerable on Sunday.

Snowpack Summary

Storm snow accumulated over the preceding week, combined with strong southwesterly winds, has built up large cornices and wind slabs on leeward aspects, especially near ridgetops.

A weak layer of surface hoar can be found in some sheltered terrain features buried 40 to 60 cm. In other areas, a melt-freeze crust can be found at similar burial depths, up to around 2000 m.

The mid and lower snowpack currently has no layers of concern.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
