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

Avalanche Summary

No new avalanches have been reported.

Numerous size 2 to 2.5 wind slab avalanches occured over the weekend.

Going forward, wind slab avalanches are still possible to human trigger.

Snowpack Summary

Roughly 15 to 30 cm of recent storm snow is wind affected at upper elevations and remains soft in sheltered terrain. This overlies heavily wind affected surfaces of hard wind slab, and wind pressed snow.

Below this, a layer of facets from early February and a thick crust from late January are at a similar depth between 70 and 110 cm deep. These layers are less likely to be triggered where a supportive crust is present.

This MIN from the Sinclair area on Monday describes soft snow with limited crust felt.

Weather Summary

Partly cloudy. 1 to 4 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Wednesday
Mix of sun and clouds. 1 to 2 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Thursday
Mostly sunny. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -9 °C.

Friday
Mostly sunny. 20 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

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.
