Regions

Maligne.

Early season hazard are still present. Watch out for wind affected snow resulting in decreased ski quality and increased avalanche hazard.

Confidence

Moderate

Avalanche Summary

No new observations

Snowpack Summary

Alpine snow heavily affected by strong northerly winds. Widespread variable depth hard wind slabs. The snow depth around Maligne lake is 15cm. The snow depth at the Parker Ridge study plot is 67cm with 3-10mm surface hoar on surface. There is a solar crust on steep slopes into alpine.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.

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.
