Regions

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

Seek out wind-sheltered terrain where you can avoid wind slabs and find great riding.

Continue to practice good travel habits.

Avalanche Summary

A few small dry loose avalanches were reported on Saturday from sunny slopes.

On Friday, a few small loose dry avalanches were reported in the Duffey area, along with a size 1.5 skier-triggered wind slab in a steep rocky area.

Snowpack Summary

Upper elevations have had some wind-effect and wind slabs may be found near ridgetops. Steep sunny slopes may be moist or have a thin surface crust, shady slopes are facetting or growing surface hoar.

30 to 50 cm of settling snow 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 only seems to be a problem where the snow has consolidated into a slab overtop, such as in wind-affected areas.

The mid and lower snowpack is well-settled and bonded, with no other 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.
