Regions

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

Choose low consequence terrain and give the storm snow a bit longer to bond.

Storm slabs may still be sensitive to rider traffic, especially in the alpine.

Confidence

Moderate

Avalanche Summary

No avalanche observations have been reported yet this season.

Please consider filling out a MIN if you are out in the mountains.

Snowpack Summary

30 to 100 cm of new snow has fallen in the past 3 days. This recent snow has been accompanied by moderate to strong south easterly winds forming larger deposits on north and west aspects.

This recent snow overlies a variety of surfaces including the ground at lower elevations.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be careful as you transition into wind-affected terrain.
  • Be cautious of buried obstacles, especially below treeline.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
