Regions

Microwave-Sinclair, North Bulkley, South Bulkley, Telkwa.

Avoid large features as wind slab avalanches, if triggered, could be large.

Seek out sheltered terrain where the best and safest riding hides.

Confidence

Moderate

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

Avalanche Summary

In Sinclair on Thursday, the field team saw several large (size 2-2.5) wind slab avalanches that failed on facets underneath the recent storm snow and wind loading. Likely occurring within the past 48 hours, on east to northeast aspects.

One size 2 avalanche was reported on a south face at 1500m in the Seaton area on Tuesday.

Snowpack Summary

15 cm of snow fell earlier in the week with warm temperatures and strong southerly winds. It fell on a wind-affected and faceted layer. Below 1300 m, recent warm temperatures and rain have formed a crust.

A layer of surface hoar has been observed at depths of 70 to 110 cm throughout the region, but no avalanches have been observed on this layer recently.

Snowpack depths vary throughout the region, but are generally around 150-200 cm deep at treeline.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Make observations and continually assess conditions as you travel.
  • Avoid slopes that sound hollow or drum-like.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
