Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Large, overhanging cornices are primed for triggering with high freezing levels and sunny skies.

Keep overhead hazards in mind, reduce exposure to slopes threatened by cornices.

Confidence

Moderate

  • We are uncertain due to variable freezing levels.

Avalanche Summary

On Tuesday, several natural and human triggered wet loose avalanches were reported up to size 1.5. This activity is expected to continue as storm snow is impacted by solar radiation.

Snowpack Summary

In the alpine, strong winds have stripped windward terrain and snow is wind affected in lee terrain features. Below 2000 m a crust has formed over a saturated upper snowpack, that may break down on steep, solar aspects during the day.

An older crust with properties that are aspect and elevation dependent is down roughly 40 cm and combined with facets.

The mid to lower snowpack is generally well settled and strong. Snowpack depth ranges from 150 to 250 cm at treeline elevations.

Cornices are reported to be large and looming. Be mindful of them overhead and when travelling on ridge tops.

Weather Summary

Wednesday Night

Friday
Sunny. 60 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2600 m.

Saturday
Mix of sun and clouds. 1 to 4 cm of snow. 70 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Be alert to conditions that change with elevation and sun exposure.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.

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.
