Regions

Cariboos, North Columbia, Blue River, McBride, Premier, Quesnel, Clemina.

Fading persistent slabs have made things easier to manage, but skiers and riders have been triggering surface slabs in wind-affected terrain. Sniff out the soft snow to keep it safe and fun.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Soft wind slabs developing in the alpine produced releases to size 1.5 with sled traffic, to size 1 with skier traffic, and ran naturally to size 2 in the southeast of the region on Thursday.

There was a widespread natural avalanche cycle during the storm on the weekend. It produced several size 3 persistent slab avalanches suspected to have run on the February crust layer. These observations were focused at treeline elevation in the east of the region.

Snowpack Summary

About 50 cm of snow since March 7 has been redistributed by strong winds in exposed alpine and treeline terrain. It sits on old wind effect at these elevations and on a melt-freeze crust to at least 1600 m. It may contain two crusts on treeline solar aspects and gave moderate, sudden test results on 60 cm-deep stellar grains in Allan Creek Thursday.

Layers from late Jan and early Feb, both made of surface hoar, facets, and/or crust, are 100 to 150 cm deep. They're showing up less in test results but may remain a problem in isolated thin-to-thick snowpack areas above the elevation of our newest crust. A north aspect at 1600 m in the lower Canoe gave moderate, propagating results on the 90 cm-deep Jan layer Wednesday.

Weather Summary

Friday Night
Partly cloudy with isolated flurries and a trace of new snow. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -12 °C.

Saturday
A mix of sun and clouds with isolated flurries and a trace of new snow, mainly on the east slope. 30 km/h northwest ridgetop wind. Treeline temperature -13 °C.

Sunday
A mix of sun and cloud with cloud increasing and flurries bringing a few cm of new snow before increasing overnight. 30 to 50 km/h west ridgetop wind, shifting south and increasing. Treeline temperature -8 °C.

Monday
Cloudy with continuing snowfall bringing. 15 to 20 cm of new snow. 50 to 80 km/h southwest ridgetop wind, increasing. Treeline temperature reaching 1 °C as freezing level jumps to 2100 m.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

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.
