Regions

South Coast, Powell River, North Shore, Tetrahedron.

Slip-and-fall hazards are a concern on the hard surfaces that now dominate the region. Plan to manage lingering wind slabs if you put in the work to find dry alpine snow.

Confidence

Moderate

Avalanche Summary

With the wet avalanche cycle from the early part of the week finished, there is some uncertainty about the amount and reactivity of snow that accumulated in the high alpine Thursday night. Any wind slabs formed with this new snow are our only real avalanche concerns over the near term.

Snowpack Summary

Limited high alpine locations in the region may have up to 20 cm of wind-redistributed recent snow on the surface. Up to 30 cm might be found in the Tetrahedron alpine.

Below the recent snow, and everywhere it didn't snow, an increasingly strong and supportive crust is forming in the uppermost part of the rain-soaked snowpack.

Below treeline coverage in many areas has returned to below threshold depth for avalanches.

Weather Summary

Saturday night

Partly cloudy. Northeast alpine wind 5 - 15 km/h. Freezing level remaining near 1400 m.

Sunday

A mix of sun and cloud. East or northeast alpine wind 10-20 km/h, increasing. Treeline temperature -1 °C with freezing levels around 1200 m.

Monday

A mix of sun and cloud. Northeast alpine wind 10-20 km/h, easing. Treeline temperature 0 °C with freezing levels around 1400 m.

Tuesday

Mainly sunny. West alpine wind 5 - 15 km. Treeline temperature -1 °C with freezing levels around 1200 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

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.
