Regions

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

Low visibility and a thin, early-season snowpack are the main hazards. Keep the chaos low- slide slow!

Confidence

Moderate

Avalanche Summary

Skiers triggered a few small (size 1) wind slabs at treeline near Revelstoke on Saturday.

Looking forward to Monday, the potential for isolated pockets of wind slab remains, but the biggest hazard is a shallow, early-season snowpack in combination with flat light or low visibility.

Please consider posting a MIN if you are heading out in the backcountry!

Snowpack Summary

Up to 10 cm of recent snowfall covers faceted snow or surface hoar in sheltered areas, firm wind-affected snow in open areas, and a thin sun crust on steep solar aspects. A supportive melt-freeze crust from mid-November is buried 40–60 cm down and is present up to about 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

Sunday Night

Increasing cloud cover. 20 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Tuesday

Mostly cloudy. Trace to 3 cm of snow at treeline. 20 km/h west ridgetop wind. Treeline temperature -7 °C.

Wednesday

Mostly cloudy. Trace to 3 cm of snow at treeline. 20 km/h northwest ridgetop wind. Treeline temperature -9 °C.

Terrain and Travel Advice

  • 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.
