Regions

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

Avoid travelling on or below steep slopes when the snow surface feels wet or slushy.

We are not quite in a spring diurnal pattern, freezing levels are expected to stay elevated overnight.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

A few small natural and skier triggered wet loose avalanches were observed Saturday afternoon. These avalanches occurred at treeline and ran on the thick crust described in the snowpack summary.

Snowpack Summary

A thin crust may exist early in the morning but it will break down quickly. The snow below is likely wet.

A thick crust can be found down 5 to 30 cm at treeline and above. The snowpack below this crust is well settled and strong.

At low elevations the snowpack is disappearing quickly. Where snow remains it is isothermal.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

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.
