Regions

Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson.

Touchy avalanche conditions continue in the region.

Back off if you see signs of instability like avalanches, cracking, or whumpfs.

Confidence

Moderate

  • We are uncertain about how the snowpack will react to the forecast weather.
  • We are uncertain due to variable freezing levels.

Avalanche Summary

No new avalanches have been reported in the past week. Signs of instability like shooting cracks and whumpfs were reported in the Pine Pass on Thursday.

New snow accumulating over the surface hoar is expected to have triggered a cycle of natural and human-triggered avalanches recently. Observations have been limited.

Please share observations like avalanches, weather, and riding conditions to the Mountain Information Network.

Snowpack Summary

30-50 cm of new snow at treeline sits on surface hoar over a widespread crust. With warm temperatures throughout the storm, this likely fell as rain as high as 1600 m in some areas of the region.

This new snow was accompanied by moderate to strong southwest winds, meaning that the crust has likely remained on the surface of southerly aspects, while deeper deposits will be found on north and east aspects. The surface hoar is largest on sheltered treeline and below-treeline features.

The lower snowpack is well settled.

Check out this MIN from the Pine Pass for more details.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.

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.

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.
