Regions

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

Dangerous avalanche conditions exist on wind-loaded slopes. Sheltered terrain, away from overhead hazard will provide the safest riding.

Confidence

Moderate

  • We are uncertain due to how buried persistent weak layers will react with the forecast weather.
  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Natural wind slab avalanches up to size 2.5 continue to be observed, likely occurring during periods of rapid loading due to strong winds. These have occurred on a variety of aspects, indicating variability in wind patterns.

Please post any photos or observations to the MIN if you head out.

Snowpack Summary

Recent snow over the last week has been redistributed by primarily southwest winds. Exposed terrain may be wind-pressed or scoured down to old crusts. While wind slab formation continues to occur in leeward or cross-loaded terrain.

Two notable layers exist in the snowpack. A layer of facets from early February, up to 40 cm deep. A thick crust from late January, 50 to 100 cm deep. Both of these layers are a concern in wind-affected terrain.

The remainder of the snowpack is well settled.

Weather Summary

Tuesday
Mostly cloudy. 3 to 4 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1100 m.

Wednesday
Mix of sun and clouds. 2 to 3 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1200 m.

Thursday
Mix of sun and clouds. 1 to 3 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Be aware of the potential for large avalanches due to buried weak layers.

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.
