Regions

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

Recent snow and strong winds are forming small wind slabs over surface hoar and crust.

Watch for signs of instability, like shooting cracks, in steep terrain.

Confidence

Snowpack Summary

Around 10 - 15 cm of recent snow is being redistributed by strong southerly winds, building small wind slabs over a layer of surface hoar.

This surface hoar layer sits on a crust found on all slopes except shaded north-facing ones, where there is a mix of soft snow from surface faceting and wind-affected snow in open terrain features.

Strong southerly winds have stripped the snowpack down to hard old surfaces and rock in exposed alpine terrain. Cornices are large and overhanging.

The lower snowpack is well settled, with the mid-December facet/crust layer buried down approximately 100 to 150 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Carefully evaluate steep lines for wind slabs.
  • Make observations and continually assess conditions as you travel.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
