Regions

Northwest Inland, Kispiox, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

New snow and wind has a buried weak layer and created dangerous avalanche conditions.

Human triggering is likely.

Travel in simple, low-consequence terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches reported on Wednesday.

On Monday, reports saw a natural storm slab at treeline elevation (size 1). For full details, check out the MIN HERE.

Natural avalanches remain possible and rider-triggered avalanches are likely on Thursday as the storm slab slowly settles.

Snowpack Summary

Up to 50 cm of new storm snow and strong southeast winds have buried old wind-affected snow in the alpine and open treeline areas, creating fresh storm and wind slabs. Unconsolidated snow exists in areas sheltered from the wind.

A layer of weak, feathery (surface hoar) crystals is buried 30 to 60 cm. Where this layer exists the new snow will likely have a poor bond.

A crust formed in November and is buried at about 60 to 100 cm with small facets above it.

At treeline, the total snowpack is about 80 to 100 cm deep and tapers quickly at lower elevations.

Weather Summary

Wednesday Night
Mostly cloudy. 4 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 400 m.

Thursday
Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -8 °C. Freezing level 0 m.

Friday
Mostly cloudy. 1 to 4 cm of snow. 10 km/h southeast ridgetop wind. Treeline temperature -12 °C. Freezing level 0 m.

Saturday
Mostly cloudy. 10 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -13 °C. Freezing level 0 m.

Terrain and Travel Advice

  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Stick to non-avalanche terrain or small features with limited consequence.
  • Keep in mind that human triggering may persist as natural avalanches taper off.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
