Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Low danger does not mean no avalanches.

Use Caution in wind effected terrain.

Continue to use good travel habits; only expose one person at a time and avoid unnecessary overhead hazards.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in the past few days.

Snowpack Summary

Around 5 cm of new snow has buried a variety of surfaces including surface hoar  and facets in sheltered terrain, a crust on south and west facing slopes as well as old wind slab on exposed terrain.

The widespread crust buried in early February is near the surface on exposed alpine terrain and down up to 25 cm elsewhere. This crust may have a layer of facets above.

The remainder of the snowpack is settled and not concerning.

Terrain and Travel Advice

  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • Be carefull around freshly wind loaded features.

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.
