Regions

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

Wind slabs may step down to deeper layers, creating very large avalanches.

Stick to sheltered, conservative terrain for the best and safest riding.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

On Tuesday, our field team reported a recent cornice-triggered size 3 persistent slab avalanche on a northeast aspect that ran to valley bottom.

Observations are limited in this region. If you are heading into the mountains, please consider filling out a Mountain Information Network report.

Snowpack Summary

Up to 10 cm of new snow will be redistributed by strong southwest winds, creating wind-pressed surfaces and wind slab in exposed alpine terrain. 20 to 40 cm of facetted snow can be found in wind-sheltered areas, and a sun crust likely exists on steep solar slopes.

A thick crust from late January can be found at a wide range of depths, from 75 to 150 cm. Where it is shallowest, facets are most likely to exist above it, and the more problematic it is expected to be.

We do not have concerns about the snowpack below this layer.

Saturday

Mix of sun and clouds. 1 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Sunday

Mostly cloudy. 2 to 4 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -2 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • In times of uncertainty, conservative terrain choices are our best defense.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

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.

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.
