Regions

Cariboos, North Columbia, Blue River, Clearwater, McBride, Premier, Quesnel, Clemina, Renshaw, Robson.

Dangerous avalanche conditions persist in the wake of the storm. Stick to conservative terrain while the snowpack adjusts to the new load.

Confidence

Moderate

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

Avalanche Summary

We are still awaiting observations from the storm on Saturday. During stormy conditions last week, a large avalanche cycle produced avalanches up to size 4, many likely stepping down to deeper weak layers. We are expecting to see similar activity this weekend.

On Wednesday and Thursday this week, a number of small (size 1) skier-triggered slabs were reported on north-facing convexities at alpine and treeline elevations. Crowns were around 30 cm deep.

Snowpack Summary

40 to 60 cm of new snow is likely wind affected at upper elevations. Below 1800 m, expect wet or crusty surfaces.

A layer buried in late January, consisting of surface hoar, facets, and/or crust, exists roughly 100 to 150 cm below the surface. Check out this blog post for more details on these problematic layers.

The remainder of the snowpack is well consolidated, with no other significant layers of concern.

Weather Summary

Saturday Night
Mostly cloudy. 10 to 20 mm of snow or rain at treeline. 70 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level dropping 2000 m to valley bottom.

Sunday
Mix of sun and clouds. 1 to 4 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -8 °C.

Monday
Mix of sun and clouds. 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mix of sun and clouds. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -11 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
