Regions

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

Expect the sun to destabilize the upper snowpack, especially on steep south-facing terrain.
Wind loaded slopes in the alpine remain the most concerning.

Confidence

High

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

No recent avalanches have been reported.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

Mid weeks storm snow accumulations are variable and have likely created deeper zones on the north and west island. Expect all this new snow to become moist and rapidly settle once the sun comes out. This will be especially prevalent on steep south aspect terrain.

Past moderate to strong southwest winds created deeper, more reactive slabs in leeward terrain. Windward terrain has been stripped of snow and scoured down to a crust in many places.

Extending to the mountain tops, a widespread, thick and hard crust is now expected to be buried by 40-80 cm of snow, likely to have moist snow underneath.

The snowpack below the crust is well settled, strong and bonded with no layers of concern.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

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.
