Regions

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

Look for areas with soft snow on the surface and be cautious as you transition into wind affected terrain.

As always, it's best to avoid areas where the snowpack transitions from thin to thick.

Confidence

High

Avalanche Summary

On Sunday skiers were involved in an avalanche in the East Boulder Creek area north of our forecast region. Check out This MIN report for more details.

Snowpack Summary

5 cm of recent snow is sitting on an old wind affected snow surface in exposed terrain at treeline and alpine elevations. At treeline and below a layer of surface hoar has now been covered by this new snow.

In sheltered terrain, 20 to 60 cm of faceted snow is sitting on a crust and in places surface hoar.

A layer of facets on top of a crust from early December is buried approximately 70 to 110 cm deep. This layer is generally not a concern in this region at this time.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.

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.
