Regions

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

Wind slabs may remain reactive for longer than usual due to an underlying crust.

For best and safest riding, seek out sheltered terrain where the snow hasn't been affected by wind.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported since last Tuesday, when explosive control produced a few dry loose avalanches, size 1.5, that ran on the weak layer below the storm snow.

Looking forward, we expect wind slabs may remain reactive to riders at upper elevations, especially if winds pick up strength over the weekend. Continue to carefully manage sluffing in steep terrain.

Snowpack Summary

In wind-exposed terrain, storm snow has been blown onto leeward slopes by recent southwesterly winds. Winds are expected to change direction on Saturday and Sunday, so expect wind slabs and wind-affected snow on all aspects. 25 to 50 cm of old storm snow may be poorly bonded to an underlying crust. The greatest concern is for wind-affected areas where the buried crust is combined with a thin layer of weak facets - particularly on high northerly slopes. The mid and lower snowpack is well-settled and dense with no other layers of concern.

Terrain and Travel Advice

  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Avoid areas where the snow feels stiff and/or slabby.
  • 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.
