Regions

Northwest Inland, Kitimat, Nass, Rupert, Seven Sisters, Shames, Howson, Microwave-Sinclair.

In a sea of wind affected surfaces, lingering wind slabs remain a concern and may be tricky to recognize.

Avoid large open slopes capable of producing large avalanches.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Several size 1-2 rider triggered wind slabs have been reported since Wednesday across a range of aspects at treeline and in alpine elevations. Check out the photos below.

A remotely triggered avalanche on Wednesday indicates these dense new slabs may be sitting over a weak crust/facet layer in some areas.

Snowpack Summary

Wind effect has shaped the snowpack. Most exposed terrain is sastrugi or has been scoured down to old crusts. On sheltered slopes, recently formed wind slabs persist at all elevations.

20 to 40 cm of snow overlies a surface hoar layer in isolated, wind-sheltered terrain features (primarily at treeline and below).

A January crust and facet layer is buried roughly 60 to 120 cm below the surface. Beneath this layer, the remainder of the snowpack is generally well settled and well bonded.

Weather Summary

Saturday Night
Partly cloudy. 1 cm of snow. 40 km/h east ridgetop wind. Treeline temperature -15 °C.

Sunday
Mostly cloudy. 1 to 2 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature -15 °C.

Monday
Mostly sunny. 3 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mostly cloudy. 1 to 5 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -6 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Wind slabs are most reactive during their formation.
  • Use careful route-finding and stick to moderate angled slopes with low consequences.

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.
