Regions

South Coast, Powell River, Tantalus, North Shore, Sasquatch, Sky Pilot, Tetrahedron, Coquihalla, Harrison-Fraser, Manning, Skagit.

Any surface crust that forms overnight will break down quickly. Start and finish your day early.

Wet loose avalanches are possible on steep slopes when the snow surface is wet.

Confidence

Moderate

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Observations are limited but likely wet loose avalanches up to size 2 occurred in steep or extreme terrain throughout the region on Sunday and Monday.

Snowpack Summary

A thin crust may form early in the morning but it will break down quickly on sun exposed slopes and at lower elevations. The snow below is likely wet.

A thick crust can be found down 5 to 25 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.

Weather Summary

Wednesday
Mix of sun and clouds. 2 to 3 mm of rain at treeline. 20 km/h west ridgetop wind. Treeline temperature 5 °C. Freezing level 2300 m.

Thursday
Mostly sunny. 1 mm of rain at treeline. 20 km/h northwest ridgetop wind. Treeline temperature 3 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Keep in mind that the high density of wet avalanches can make them destructive.

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.
