Regions

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

Wind slabs remain possible to human trigger.

Continually assess as you travel. If the snow looks wind-affected or feels dense or stiff, back off.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

On Saturday, a very large natural wind slab avalanche was reported that occurred during the storm.

Snowpack Summary

New low density snow is incrementally accumulating and being redistributed by moderate southwest wind over a mix of moist or refrozen recent storm snow.

At upper elevations heavily wind affected surfaces can be found. Hard wind slab, and wind pressed snow with new small wind slabs forming are likely.

Below this, a layer of facets from early February is roughly 50 cm deep, and a thick crust from late January up to 100 cm deep. These layers are less likely to be triggered where a supportive crust is present.

Weather Summary

Monday Night
Partly cloudy. 1 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mix of sun and clouds. 1 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Wednesday
Mix of sun and clouds. 1 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Thursday
Mostly sunny. 10 km/h west ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

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.
