Regions

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

Watch for isolated wind slabs at upper elevations. Conditions remain rugged at lower elevations, so choose objectives suited to early-season hazards.

Moderate

Avalanche Summary

No recent avalanches have been reported, but observations are limited at this time of year. Please consider posting a MIN if you are heading out in the backcountry!

Isolated pockets of wind slab could exist in exposed areas. Low-density surface snow may sluff and run far in steep terrain features.

Snowpack Summary

Up to 5 cm of recent snowfall covers wind effect in exposed alpine areas and a thin sun crust on steep solar aspects. Last week's 40 to 60 cm of settling storm snow sits above a rain crust buried mid-November up to approximately 2200 m.

The average snow depths at treeline elevation are anywhere from 70 to 100 cm.

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

Weather Summary

Friday Night

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

Saturday

A mix of sun and cloud. Up to 1 cm of new snow at treeline. 5 to 10 km/h southeast ridgetop wind. Treeline temperature -9 °C.

Sunday

Increasing cloud cover. 10 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Monday

Mostly cloudy. Trace to 5 cm of new snow. 10 km/h west ridgetop wind. Treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • 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.
