Regions

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

Exercise caution around steep slopes, where wet surface snow may remain unstable.

Confidence

Moderate

Avalanche Summary

No new avalanche was reported, but field observations are limited. Old debris of large natural wet avalanches from the past weekend's storm is still visible throughout the region.

Snowpack Summary

The top meter of the snowpack is wet. Where still intact, a crust buried in January may be found 100 to 150 cm deep. Below this, the snowpack is well bonded and stable. At lower elevations, the snowpack is isothermal and the coverage is thin.

Weather Summary

Friday night

Cloudy. 20 to 40 km/h south ridgetop wind. Treeline temperature +2°C. Freezing level 2700 m.

Saturday

Cloudy with flurries starting in the afternoon. 40 to 50 km/h south ridgetop wind. Treeline temperature +5°C. Freezing level lowering from 2800 to 1500 m.

Sunday

5 to 10 cm of snow overnight then clearing to a mix of sun and cloud. 20 to 30 km/h northwest ridgetop wind. Treeline temperature +2°C. Freezing level around 1700 m.

Monday

Sunny. 10 to 20 km/h northeast ridgetop wind. Treeline temperature +3°C. Freezing level around 1800 m.

Terrain and Travel Advice

  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • The snowpack is generally stable; it may be appropriate to step out into more complex 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.
