Regions

South Coast, Powell River, North Shore, Sky Pilot, Tetrahedron.

If a surface crust is present avalanche danger is likely low.

If there is no crust and the surface becomes wet and breaks down the danger will rise.

Confidence

Moderate

Avalanche Summary

Moist snow, pinwheeling and small loose wet sluffing was reported at 1200 m near Cypress on Saturday.

Snowpack Summary

A crust is likely to form overnight as the surface cools after Monday's warm temperatures.

The mid and lower snowpack is well consolidated, with several well-bonded crusts scattered throughout.

Snow depth has been reported as 330 cm at 1700 m, tapering quickly with elevation below treeline.

Weather Summary

Monday Night

Mostly clear skies. 10 km/h north ridgetop wind. Treeline temperature 0 °C. Freezing level 3000 m.

Tuesday

Cloudy. 10 to 20 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 2500 m.

Wednesday

5 to 10 cm of snow overnight then clearing. 10 to 20 km/h west ridgetop wind. Treeline temperature +1 °C. Freezing level 1500 to 2500 m.

Thursday

Mostly sunny in the morning, with increasing clouds in the afternoon. 20 to 40 km/h south ridgetop wind. Treeline temperature +4 °C. Freezing level 2700 m.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
