Regions

Northwest Inland, Kispiox, Microwave-Sinclair, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

Assess steep lines at upper elevations for wind slab.

Wind slabs may be more reactive where they overlie facets or surface hoar.

Confidence

Moderate

Avalanche Summary

Over the past few days rider triggered wind slabs up to size 2 have been reported in the treeline and alpine. take a look at this MIN for a good photo of a recent skier triggered avalanche.

If you go into the backcountry, consider submitting a MIN report.

Snowpack Summary

5 to 10 cm of recent storm snow has been redistributed into wind slab by variable winds. In sheltered terrain this new snow could overlie a layer of surface hoar, facets or a crust.

The remainder of the snowpack is generally not concerning.

Check out this great MIN for more details on conditions.

Weather Summary

Tuesday Night

Clear skies with no new snow expected. 20 to 40 km/h northeast alpine wind. Treeline temperature -6°C with a temperature inversion and colder temperatures below treeline.

Wednesday

Clear skies with no new snow expected. 20 to 40 km/h east alpine wind. Treeline temperature -8°C.

Thursday

Clear skies with no new snow expected. 25 to 50 km/h east alpine wind. Treeline temperature -6°C.

Friday

Clear skies with no new snow expected. 40 to 70 km/h southeast alpine wind. Treeline temperature -6°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

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.
