Regions

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

In a sea of wind affected surfaces, 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.
  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Several size 1-1.5 rider triggered wind slabs have been reported in the last 3 days. Recent activity has mainly occurred at treeline elevations and on north or west facing slopes. Check out the photos below.

Dry loose sluffing to size 2 has also been noted from extreme, wind sheltered terrain where faceting is affecting the snowpack.

Snowpack Summary

Outflow winds have sculpted the snowpack. Most exposed terrain is sastrugi or has been scoured down to old crusts. On sheltered slopes, wind slabs persist.

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 60 to 120 cm deep. Below, the remaining snowpack is generally well settled and well bonded.

Weather Summary

Sunday Night
Mostly cloudy. 1 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Monday
Mostly cloudy. 1 to 2 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Tuesday
Mostly cloudy. 4 to 10 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -4 °C.

Wednesday
Mostly cloudy. 10 to 25 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Use careful route-finding and stick to moderate angled slopes with low consequences.
  • Outflow winds may form wind slabs at all elevations.

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.
