Regions

Cariboos, South Columbia, Blue River, Jordan, North Monashee, North Selkirk, West Purcell, Badshot-Battle, Central Selkirk, Goat, Gold, Valhalla, Whatshan.

Use careful route-finding to stay on low-consequence slopes at all elevations.

Storm slabs will remain reactive longer than usual due to the underlying weak layer.

Confidence

Moderate

  • We are uncertain about how the snowpack will react to the forecast weather.

Avalanche Summary

On Saturday, numerous wind and storm slabs (size 1 to 1.5) were triggered by skiers and sledders in the region. A few large natural slabs (size 2.5 to 3) occurred near Revelstoke with a significant propagation along an alpine ridgetop from a north-facing slope.

These avalanches were triggered on a variety of aspects in the alpine and treeline, they failed on the late January surface hoar layer mentioned in the snowpack summary.

Snowpack Summary

20 to 40 cm of snow now overlies the late January surface hoar/crust layer. This new snow has been accompanied by moderate to strong south and west wind, meaning that the crust will likely remain on the surface on southerly aspects and deeper deposits will be found on north and east aspects.

The late January surface hoar is largest on sheltered treeline and below treeline features and may not exist on exposed terrain in the alpine.

The snow surface is likely become moist up to 1900 meters and on south aspects due to warm temperatures from Saturday.

The mid and lower snowpack is well settled.

Monday
Cloudy. 10 to 15 cm of snow at treeline. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1600 m.

Tuesday
Cloudy. 5 to 10 cm of snow at treeline. 50 km/h southwest ridgetop wind. Treeline temperature -1°C. Freezing level 2000 m.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

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.
