Regions

South Coast, Powell River, North Shore, Sasquatch, Sasquatch, Tetrahedron.

Low hazard is not no hazard.

Small human-triggered avalanches are still possible in steep terrain where the snow surface remains moist.

Confidence

High

Avalanche Summary

On Tuesday, ski cutting produced small wet loose avalanches up to size 1.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. Current condition information and photos are helpful for forecasters.

Snowpack Summary

A dusting of new snow covers refrozen surfaces surface at treeline and above. Below the crust the upper 60 cm of the snowpack is moist.

A few buried crusts are found 100 to 170 cm down, though they have become unreactive with the cooling temperatures. The mid and lower snowpack is well settled and dense.

Weather Summary

Wednesday Night

Cloudy. 10 to 25 km/h southeast ridgetop wind. Treeline temperature -2°C with freezing level falls to 1200m.

Thursday

Cloudy with 0 to 2 cm of snow. 10 to 25 km/h southwest ridgetop wind. Treeline temperature -1°C. Freezing level 1300m.

Friday

Cloudy with 1 cm of snow. 10 to 20 km/h southeast ridgetop wind. Treeline temperature 0°C. Freezing level 1500m.

Saturday

Cloudy with 5 to 15 cm of snow. 20 to 40 km/h northeast ridgetop wind. Treeline temperature 0°C. Freezing level 1500m.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

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.
