Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Beware of wind slabs in steep, alpine terrain. Recent wind has varied in direction and strength.

Confidence

High

Avalanche Summary

A few small (size 1) loose avalanches were reported on Tuesday, and some skier-triggered wind slabs were reported in alpine terrain on Monday (up to size 1.5).

Snowpack Summary

Variable wind has redistributed low-density snow at higher elevations.

A layer of surface hoar may exist 10 to 20 cm below the surface and a widespread, supportive crust exists 30 cm below the surface.

Snowpack depths decrease rapidly as you lose elevation below treeline.

Terrain and Travel Advice

  • Start on smaller terrain features and gather information before committing to bigger terrain.
  • Carefully evaluate steep lines for wind slabs.
  • Closely monitor how the new snow is bonding to the old 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.
