Regions

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

Large, natural avalanches are expected to occur at upper elevations on Thursday.

Travel in alpine terrain is not recommended.

Confidence

Moderate

  • We are uncertain due to variable freezing levels.

Avalanche Summary

Large, natural avalanches are expected to occur in the alpine on Thursday.

Wet loose avalanches are expected at treeline and below.

Snowpack Summary

80 to 120 cm of forecast snow above 1600 m and strong south wind will likely trigger a natural storm slab avalanche cycle on Thursday.

Below 1600 m, rain may trigger wet loose avalanches.

The recent snow overlies a hard crust in most locations.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 70 to 175 cm at treeline elevations.

Weather Summary

Wednesday Night
Cloudy. 50 to 70 cm of snow above 1200 m (rain below). 50 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1500 m.

Thursday
Cloudy. 35 to 50 cm of snow above 1600 m (rain below). 40 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1900 m.

Friday
Cloudy. 30 to 40 cm of snow above 1300 m (rain below). 50 km/h south ridgetop wind. Treeline temperature 2 °C. Freezing level 1600 m.

Saturday
Mostly cloudy. 30 km/h south ridgetop wind. Treeline temperature 3 °C. Freezing level 2500 m.

Terrain and Travel Advice

  • Travel in alpine terrain is not recommended.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.
  • Be alert to conditions that change with aspect and elevation.
  • Avalanche danger will rapidly increase if snow switches to rain.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

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.
