Regions

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

Adjust your approach to terrain as you gain elevation.

Wind slabs are the main hazard at higher elevations, while early season hazards exist just below the snow surface at lower elevations.

Confidence

Moderate

Avalanche Summary

A size 1.5 skier-triggered avalanche was reported on Tuesday on a north-east aspect. This avalanche ran on the surface hoar described in the snowpack summary. Check out this Mountain Information Network report for more details.


 A few small, natural wind slab avalanches were observed on westerly aspects by our field team on Thursday. These avalanches likely occurred over the past 24 to 48 hours.

Snowpack Summary

5 to 10 cm of previous storm snow overlies old wind-affected snow and wind slab.

On sheltered features, a new surface hoar layer is down up to 20 cm. The early November crust is buried at about 60 cm and may have small facets above it in these locations.

At treeline, the snowpack depth ranges from 60 to 80 cm, decreasing to about 30 cm at valley bottom.

Weather Summary

Saturday Night
Mostly clear skies. 10 km/h west ridgetop wind. Treeline temperature -5 °C.

Sunday
Mix of sun and clouds. 30 km/h west ridgetop wind. Treeline temperature -3 °C.

Monday
Mostly cloudy. 3 to 5 mm of precipitation as snow or rain at treeline. 40 km/h west ridgetop wind. Treeline temperature -2 °C.

Tuesday
Mostly cloudy. 1 to 2 mm of precipitation as snow or rain at treeline. 40 km/h northwest ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be cautious of buried obstacles, especially below treeline.

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.
