Regions

Vancouver Island.

As the freezing level falls avalanche activity will become unlikely.

Confidence

High - We have a good understanding of the snowpack structure and confidence in the weather forecast

Weather Forecast

Tuesday night: Light flurries bringing trace amounts of snow at higher elevations with freezing levels around 1800 m. Moderate south winds.

Wednesday: Clearing throughout the day. Light flurries bringing 5 to 10 cm of new snow. Freezing level falling to 1100 m. Light to moderate westerly winds.

Thursday: Mostly cloudy with no new snow expected. Freezing levels around 1300 m. Light southeast winds.

Friday: Mostly cloudy with flurries bringing trace amounts of snow. Light to moderate southeast winds and freezing levels around 1200 m.

Avalanche Summary

No avalanches were reported on Monday.

Snowpack Summary

Wind slabs could be found at higher elevations on northerly aspects. As the freezing level falls a crust will likely form on all aspects and elevations. .

Below treeline, snowpack depths are below threshold for avalanches in many areas.

Terrain and Travel

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Wind slabs may be poorly bonded to the underlying 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.
