Regions

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

Be especially cautious in steep, wind-affected terrain where triggering slabs is most likely.

Confidence

Moderate

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

Avalanche Summary

On Wednesday, a large (size 3) persistent slab avalanche was reported west of the forecast region. The avalanche ran on an east aspect in the alpine. This observation indicates that the persistent slab problem continues to be a concern in this forecast region.

Snowpack Summary

A dusting of new snow covers surface hoar. This overlies 10 to 15 cm of faceting snow from recent cold temperatures.

This new snow overlies wind-affected snow, with wind slabs in lee terrain features. Wind slabs remain reactive and are slow to bond to previously heavily wind-pressed surfaces. A surface crust can be found up to 1500 m.

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. This layer remains possible to trigger with large loads and is likely found more easily on north-facing slopes.

Weather Summary

Friday Night

Mostly clear skies. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -15 °C.

Saturday

Mix of sun and clouds. 1 to 3 cm of snow. 30 to 40 km/h west ridgetop wind. Treeline temperature -14 °C.

Sunday

Mix of sun and clouds. 2 to 5 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -13 °C.

Monday

Mostly cloudy. 5 to 15 cm of snow at treeline. 50 km/h south ridgetop wind. Treeline temperature -7 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • 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.
