Regions

North Columbia, South Columbia, Glacier, Esplanade, Jordan, North Selkirk, Dogtooth, West Purcell, Badshot-Battle, Central Selkirk, Goat, Gold, Retallack, Valhalla, Whatshan.

Rider-triggered slabs are possible at upper elevations, especially on wind affected slopes. Below treeline, early-season hazards like open creeks, rocks, and stumps remain.

Confidence

Moderate

Avalanche Summary

A natural cycle occurred last week during the storm; slab avalanches up to size 3.5 were reported throughout the region.

Since then, natural avalanche activity has tapered, but rider-triggered slabs (up to size 2) remain possible. Watch for whumphing and cracking in the upper snowpack, and use extra caution in wind-loaded terrain.

Low-density surface snow may sluff and run far in steep terrain features.

Snowpack Summary

Last weekend's storm brought 40 to 60 cm of new storm to treeline and above. This recent storm snow sits above a raincrust buried mid-November up to approximately 2200 m. A suncrust may exist on steep south-facing slopes.

The average snow depths at treeline elevation are anywhere from 70 to 90 cm.

Below treeline the snowpack tapers significantly. Watch out for variable snow conditions and quality, as well as early-season hazards such as open creeks, rocks and stumps.

Weather Summary

Thursday Night

Mostly clear skies. 1 to 2 cm of snow at treeline. 10 km/h south ridgetop wind. Treeline temperature -7 °C.

Friday

Sunny. 20 to 40 km/h northwest ridgetop wind. Treeline temperature -10 °C.

Saturday

Mostly sunny. 1 cm of snow at treeline. 10 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Sunday

Sunny. 10 km/h west ridgetop wind. Treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Make observations and continually assess conditions as you travel.
  • Be cautious of buried obstacles, especially below treeline.

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.
