Regions

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

It's still a good time of year to be cautious with your movement and terrain selection.

It will be tricky to determine if and where the buried weak layer will avalanche.

Low

Avalanche Summary

No new avalanches have been reported since Thursday.

Looking forward to Monday, we expect that the small bit of new snow will not change avalanche conditions. We are unsure about the potential reactivity of the buried surface hoar related to this Mountain Information Network report. A lack of avalanche reports could mean that it has bonded to the rest of the snowpack, but we require more field observations to be certain.

Snowpack Summary

A bit of new snow will give a light refresh in sheltered areas around treeline and above, and moderate to strong southwest wind may be forming small pockets of wind slab on leeward slopes. This new snow covers settled snow and wind-affected surfaces.

Below treeline, rain is expected to moisten the surface snow.

On sheltered features, a surface hoar layer is buried up to 25 cm. The early November crust is buried at about 60 cm and may have small facets above it.

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

Weather Summary

Sunday Night
Cloudy. 3 to 5 mm of precipitation as snow or rain at treeline. 25-40 km/h west ridgetop wind. Treeline temperature -3 °C.

Monday
Mostly cloudy. 1 to 3 mm of precipitation as snow or rain at treeline. 35-55 km/h west ridgetop wind. Treeline temperature -1 °C.

Tuesday
Mostly cloudy. 1 to 3 mm of precipitation as snow or rain at treeline. 40 km/h northwest ridgetop wind. Treeline temperature -2 °C.

Wednesday
Mostly cloudy. 2 to 3 cm of snow at treeline. 40 km/h west ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Be alert to conditions that change with aspect and elevation.
  • 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.
