Regions

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

Although natural avalanche activity is tapering off, new snow may still be reactive to human triggering due to a buried weak layer.

Confidence

Moderate

Avalanche Summary

On Tuesday, avalanche control with explosives produced a few dry loose avalanches, size 1.5, that ran on the weak layer below the storm snow.

We expect new snow will remain reactive to skier traffic on Friday, anywhere winds have formed slabs. Carefully manage sluffing in steep terrain.

Snowpack Summary

Around 30 to 60 cm of storm snow has accumulated recently and may be poorly bonded to underlying layers. The storm snow overlies a hard melt-freeze crust in most areas and a weak layer of facets and/or surface hoar on high north-facing slopes. In wind-exposed terrain, storm snow has been redistributed by moderate to strong southwest wind.

The mid and lower snowpack is well-settled and dense with no other layers of concern.

Weather Summary

Thursday Night

Clear. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -8 °C.

Friday

Cloud increasing through the day. 15 to 25 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Saturday

Partly cloudy with light flurries, 1 to 4 cm of snow. 30 to 50 km/h northwest ridgetop wind. Treeline temperature -3 °C.

Sunday

Partly cloudy. 30 to 50 km/h northwest ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Make observations and continually assess conditions as you travel.

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.
