Lo esencial

Continued wind and light snowfall into the weekend will keep wind slabs as the main concern.

    Wind slabs may remain triggerable to riders. Assess for slabs in lee terrain features prior to committing.

    A weak layer of facets may exist above a hard melt-freeze crust that formed in early February.

Moderate

Avalanche Summary

We have not received any reports of avalanche the last few days.

Snowpack Summary

Moderate southwest wind is expected to continue to redistribute fresh snow, forming wind slabs in lee terrain features near ridges. Soft snow may prevail in terrain sheltered from the wind.

A thick and hard widespread crust that formed in early February is buried 40 to 60 cm deep. This crust may have a weak layer of facets sitting above it.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
