Regions

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

The main concern is newly formed wind slabs at upper elevations.

Avoid steep slopes where the snow feels denser or wind-affected.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.
  • Uncertainty is due to how quickly the snowpack will recover and gain strength.

Avalanche Summary

Several natural and human-triggered slabs occurred during last week’s stormy weather (see photos), but there were no reports of new avalanches occurring over the weekend. No persistent slab avalanches have been reported in the past week, leaving uncertainty around this problem.

Snowpack Summary

Shifting winds have formed wind slabs on many upper-elevation aspects. A crust buried 30 to 50 cm deep extends to about 1400 m, and wind slabs may bond poorly to it.

In sheltered areas, surface hoar layers are buried 60 to 100 cm deep. Triggering is unlikely, but consequences could be high.

Snowpack depth varies widely, averaging around 150 cm at treeline and thinning quickly at lower elevations.

Weather Summary

Monday Night
Mostly cloudy. 2 to 3 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature -20 °C.

Tuesday
Mix of sun and clouds. 0 to 1 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -17 °C.

Wednesday
Mix of sun and clouds. 2 cm of snow. 50 km/h east ridgetop wind. Treeline temperature -16 °C.

Thursday
Mostly sunny. 20 km/h southwest ridgetop wind. Treeline temperature -17 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Cautiously approach steep slopes that are open or sparsely treed.

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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
