Regions

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

Expect to find reactive wind slabs formed by recent wind and new snow.

Wind loaded, leeward slopes are most concerning.

Confidence

High

  • We are uncertain due to the variability of wind effect on the snowpack.
  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

On Tuesday, north of Chilliwack, small (size 1), rider controlled, wet loose avalanches were reported on east aspects around 1300 m.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

This weeks moderate southwest ridgetop wind has created deeper deposits on leeward features.

The upper snowpack is mostly dry, settling snow above 1300 m, and moist or wet snow below 1300 m.

At elevations above 2200 m a widespread, thick and hard crust is now expected to be buried by 15-40 cm of snow.

The snowpack below the crust is strong and bonded with no layers of concern.
There is little to no snow below 1000 m.

Weather Summary

Friday Night
Partly cloudy. 30 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Saturday
Mostly cloudy. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Sunday
Mix of sun and clouds. 1 to 4 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Monday
Mostly sunny. 1 to 2 cm of snow. 10 km/h northwest ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Closely monitor how the new snow is bonding to the crust.

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.
