Regions

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

Wind-sheltered terrain should still offer excellent riding conditions. Wind slabs may persist in exposed terrain features at higher elevations.

Avalanche Summary

A natural wind slab avalanche cycle has occurred since late last week during active wind transport from northerly winds.

If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Unconsolidated powder snow continues to be found in wind-sheltered terrain. While recent northerly winds have heavily affected snow surfaces in wind-exposed terrain at treeline and above.

An old crust is present down roughly 40 to 80 cm from the surface. In isolated areas, the overlying snow may not be bonding great to this crust.

The lower snowpack consists of several layers of facets, surface hoar, and crusts, none of which appear to be an active concern currently.

Weather Summary

Sunday Night

Clear with no precipitation, northwest alpine winds 10 to 30 km/h, treeline temperature -12 °C.

Monday

Sunny with no precipitation, northwest alpine winds 0 to 20 km/h, treeline temperature -8 °C.

Tuesday

Cloudy with trace snow amounts, southwest alpine winds 0 to 20 km/h, treeline temperature -8 °C.

Wednesday

Cloudy with 5 to 10 cm of snow, southwest alpine winds 10 to 40 km/h, treeline temperature -12 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.

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.
