Regions

Kitimat, Nass, Rupert, Seven Sisters, Shames, Howson.

The best riding conditions will be found in areas sheltered from the wind.

Confidence

High

Avalanche Summary

No new avalanches have been reported in the last four days.

Snowpack Summary

Previous strong to extreme winds have scoured exposed terrain on all aspects at treeline and alpine elevations. At treeline and below, a layer of surface hoar has formed on all aspects.

Two layers of surface hoar have been reported in the upper 60 cm of the snowpack, there hasn't been much avalanche activity on these layers.

A layer of facets on top of a crust from early December is buried 100 to 200 cm deep. This layer is generally not a concern in this region.

Weather Summary

Saturday Night

Cloudy with furries. 40 to 50 km/h southeast ridgetop wind. Treeline temperature -7 °C.

Sunday

Mostly cloudy. 10 to 30 km/h south ridgetop wind. Treeline temperature -5 °C.

Monday

Clear. 0 to 10 km/h west ridgetop wind. Treeline temperature -3 °C.

Tuesday

Mix of sun and cloud. 20 to 40 km/h south ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Avoid steep terrain that is rocky and thin.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
