Regions

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

Stormy conditions are creating very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

Confidence

High

  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

A number of small (size 1) skier-triggered slabs were reported in the past couple of days, on north-facing convexities at alpine and treeline elevations. Crowns were around 30 cm deep.

On Tuesday, a natural size 3 avalanche ran on a buried weak layer on a treed west-facing knob.

During stormy conditions last week, a large avalanche cycle produced avalanches up to size 4, many likely stepping down to deeper weak layers. We may see similar activity this weekend.

Snowpack Summary

New snow continues to accumulate over a variety of old surfaces. By the end of the day Saturday, 30 to 60 cm is expected, with snow turning to rain below 1200 m.

A layer buried in late January, consisting of surface hoar, facets, and/or crust, exists roughly 80 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 significant layers of concern.

Weather Summary

Friday Night
Cloudy. 10 to 25 cm of snow. 70 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1500 m.

Saturday
Cloudy. 10 to 30 mm of precipitation as snow or rain at treeline. 70 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 1700 m.

Sunday
Mix of sun and clouds. 2 to 5 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -5 °C.

Monday
Mix of sun and clouds. 4 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
  • 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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
