Regions

Vancouver Island, East Island, North Island, South Island, West Island.

It's rugged out there! Just enough snow for some transceiver practice. With this thin coverage, a slip or fall in steep terrain could have high consequences.

Confidence

Low

Avalanche Summary

So far this season no avalanches have been reported on the Island. This should stay the same until we see another substantial snowfall.

Alpine climbers looking to extend their season might be the most likely candidates to encounter the limited avalanche hazard that currently exists.

Snowpack Summary

In most areas of the Island where snow coverage exists, a firm crust is likely to be found on or very near the surface. Light amounts (5-10 cm) of dry snow may be found on north-facing terrain at high elevations. Areas like this remain the exception, with snow coverage all over the Island generally remaining thin and patchy, especially at treeline and below.

Snowpack height at treeline currently ranges from less than 20 cm at Mt Arrowsmith to around 50 cm in Strathcona Park to 30 cm at Mt Cain.

Terrain and Travel Advice

  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

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.
