Points saillants

A buried weak layer is scary deep and yet shallow enough to trigger.

Choose conservative terrain and look for signs of instability as you're moving through it.

    Storm slabs are sitting on a heavily faceted layer from the prolonged cold period.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

The field team saw several natural wind slab avalanches above Fraser Chutes on Thursday. Up to size 2.5 in size (large). Read the full report here.

Snowpack Summary

Moderate to strong wind has redistributed 40-65 cm of storm snow over a very suspect, heavily wind-affected, and faceted snowpack. The bottom 70-100 cm of the snowpack consists of facets.

Snowpack depths vary widely due to wind, but average around 150 cm across the region.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Avoid slopes that sound hollow or drum-like.
  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
