Regions

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

A soggy snowpack likely makes for sub-par travel conditions.

If you venture out, watch for loose wet avalanches gathering mass on steep slopes.

Confidence

High

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

Avalanche Summary

Sluffing and pinwheeling were reported on Monday, although observations are limited. We expect a more widespread avalanche cycle occurred throughout the heavy rain.

Wet loose activity continues to be possible as temperatures remain elevated and rain continues.

Snowpack Summary

Rain continues to saturate the snowpack with 10-30 cm of wet snow sitting above a widespread, thick crust.

Below, the remainder of the snowpack is generally settled and well-bonded.

Weather Summary

Cloudy. 15 to 45 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2400 m.

Wednesday
Mostly cloudy. 1 to 10 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2100 m.

Thursday
Mostly cloudy. 5 to 25 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2000 m.

Friday
Mostly cloudy. 10 to 40 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Make observations and continually assess conditions as you travel.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

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.
