Regions

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

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

Confidence

High

Avalanche Summary

A few skier-triggered wind slab avalanches, up to size 1.5 in alpine terrain were reported on Monday.

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

Snowpack Summary

Recent low-density snow has been redistributed by variable winds at higher elevations.

A layer of surface hoar may exist down roughly 10 to 20 cm. While a widespread, supportive crust is down about 30 cm from the surface.

Snowpack depths decrease rapidly as you lose elevation below treeline.

Weather Summary

Tuesday Night

Clear skies. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -10 °C.

Wednesday

Sunny. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -10 °C.

Thursday

Sunny. 20 to 40 km/h northeast ridgetop wind. Treeline temperature -12 °C.

Friday

Sunny. 10 to 30 km/h southeast ridgetop wind. Treeline temperature -10 °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.
  • 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.
