Regions

Sea To Sky, South Coast Inland, Homathko, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Wind slabs continue to be reactive to human triggering. Seek out wind-sheltered terrain and watch for terrain traps.

Avalanche Summary

On Monday, a large wind slab was remote triggered by a skier at ridgeline in the alpine around the Hurley area.

A few small dry loose avalanches were reported on Saturday and Sunday from steep slopes.

Snowpack Summary

Alpine areas have been affected by the wind reducing riding quality. In sheltered areas the cold is keeping the surface soft.

30 to 50 cm overlies a weak layer from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be faceted grains or surface hoar. This layer hasn't been producing avalanches, but may become a problem when more snow arrives.

The mid and lower snowpack has no layers of concern.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
