Regions

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

Carefully assess steep lines for wind slab. The best riding will likely be found in sheltered treeline terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported but observation are limited.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Up to 20 cm of recent storm snow has been redistributed in to wind slabs by southerly winds in the alpine and treeline. This new snow rests over a crust on all aspects below 1800 m. The best riding will be found in sheltered treeline terrain.

The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. Reports indicate these are not currently a concern.

Weather Summary

Thursday Night

Mostly cloudy with up to 5 cm of new snow expected, south alpine wind 30 to 50 km/h, freezing level around 1200 m.

Friday

Mostly cloudy with a few centimeters of new snow expected, southwest alpine wind 30 to 50 km/h, freezing level rising to 1900 m.

Saturday

Mostly cloudy with light rain expected, south alpine wind 40 to 70 km/h, freezing level rising to 2200 m.

Sunday

Cloudy with up to 10 mm of rain expected, south alpine wind 50 to 70 km/h, freezing level rising  to 2400 m.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Closely monitor how the new snow is bonding to the old surface.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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 Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
