Regions

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

We are uncertain how the buried persistent weak layer will react to the forecasted warming.

In times of uncertainty, conservative terrain choices are our best defense.

Confidence

Moderate

  • We are uncertain due to how buried persistent weak layers will react with the forecast weather.

Avalanche Summary

On Sunday, riders triggered small slabs (size 1 to 1.5) from convex slopes at treeline and below on various aspects in the region. A few remote-triggered avalanches (size 2) were also reported from easterly treeline slopes. These avalanches released on the late January surface hoar layer/crust mentioned in the snowpack summary.

Large avalanche debris (size 2.5 to 3) from the weekend is still visible, particularly on north to east alpine and treeline slopes.

Snowpack Summary

10 cm of new snow now buries old surfaces, including a sun crust on south to east aspects, wind slabs in open areas and settling storm snow on north to east aspects. Moderate to strong south and west wind have affected the snow distribution, creating deeper deposits on lee slopes.

The late January surface hoar/crust layer is 30 to 50 cm deep and has shown signs of recent reactivity in the past 4 days, especially in sheltered treeline and below treeline features.

At 1900 meters and below, the snow surface is moist due to daytime warming. The mid and lower snowpack is well settled.

Weather Summary

Monday Night
Cloudy. 2 to 4 cm of snow at treeline. 30 km/h west ridgetop wind. Treeline temperature -5 °C. Freezing level 1400 m.

Tuesday
Mostly cloudy. 30 km/h southwest ridgetop wind. Treeline temperature -3°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.

Thursday
Mostly sunny. 40 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 3200 m.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • 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.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
