Regions

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

Low danger doesn't mean no danger, small wind slabs may remain triggerable at higher elevations.

Confidence

High

Avalanche Summary

Several size 1 slab avalanches were triggered by riders on Saturday, 10-30 cm deep, in the alpine and treeline.

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

Snowpack Summary

5 to 10 cm of new snow redistributed by recent winds overlies previously well-settled or wind-affected firm surfaces which may have a layer of weak, feathery crystals on top.

Below this, there is a thick and hard melt-freeze crust that extends into the alpine. The new snow buries this crust at lower elevations.

Weather Summary

Sunday Night

Partly cloudy. 30 to 50 km/h northwest ridgetop wind. Treeline temperature -10 °C.

Monday

Cloudy. 30 to 40 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Tuesday

Partly cloudy. 30 km/h north ridgetop wind. Treeline temperature -8 °C.

Wednesday

Few clouds. 20 to 30 km/h northeast ridgetop wind. Treeline temperature -10 °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.
