Regions

South Coast, Powell River, North Shore, Sasquatch, Tetrahedron.

Wind slabs may remain triggerable on lee slopes.

Carefully assess for slabs before entering big or committing terrain features.

Caution on sunny slopes if the snow surface is moist or wet.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanches have been reported. A few small (size 1) wind slabs and wet loose avalanches were observed on Wednesday.

Looking forward, triggering wind slabs and wet loose avalanches may be possible on Saturday.

If you head out, please consider posting your observations to the Mountain Information Network.

Snowpack Summary

Flurries and strong westerly winds have built some dry snow and wind slabs over previously well-settled snow from earlier this week.

The sun may melt the surface snow on sunny aspects on Saturday, creating potential for wet loose sluffing.

Reports from the North Shore suggest a strong, well-bonded snowpack. Observations elsewhere are limited, but it is possible that parts of the region with terrain above 1500 m could have 30 to 60 cm of storm snow that is poorly bonded to a crust layer.

Typical treeline snow depths range from 100 to 150 cm and thin quickly below treeline, especially on south-facing slopes.

Weather Summary

Friday Night
Partly cloudy. 30 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 900 m.

Saturday
Mostly sunny. 10 km/h northwest ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1500 m.

Sunday
Sunny. 10 km/h northwest ridgetop wind. Treeline temperature 5 °C. Freezing level rising to 2500 m.

Monday
Sunny. 30 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 2200 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.

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.
