Regions

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

It's a good day to make conservative terrain choices.

Storm slabs will remain reactive, and remote-triggering is likely, even on small features.

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 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

An additional 10 cm of snow is expected on Sunday, bringing a total of 30 to 50 cm of snow over 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.

Weather Summary

Sunday Night
Cloudy. 2 to 5 cm of snow at treeline. 40 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1600 m.

Monday
Cloudy. 5 to 10 cm of snow at treeline. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 1500 m.

Tuesday
A mix of sun and clouds. 40 km/h west ridgetop wind. Treeline temperature -1°C. Freezing level 2000 m.

Wednesday
A mix of sun and clouds. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2700 m.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.

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.
