Regions

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

Fresh snow is accumulating over unstable surfaces. Watch for slab property in the new snow, especially at wind-affected elevations.

Confidence

Moderate

Avalanche Summary

We are still awaiting observations from the storm. We expect avalanches on Friday were small but easily triggered by riders. Avalanche size and sensitivity will likely increase as snowfall continues overnight.

Snowpack Summary

Light snowfall continues. 15 to 30 cm of new snow has accumulated since Thursday night. Near ridgetops, moderate southwest wind has loaded new snow into leeward terrain features. The new snow is not expected to bond well to underlying surfaces including a crust, facets and/or surface hoar.

The mid and lower snowpack is well-settled and dense with no layers of concern.

Weather Summary

Friday night

Cloudy with 5 to 10 cm of snow. 25 to 35 km/h southwest ridgetop wind. Treeline temperature -5 dropping to -12 °C. Freezing level dropping from 1000 m to valley bottom.

Saturday

Cloudy with 1 to 5 cm of snow. 15 to 25 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Sunday

Cloudy with 1 to 5 cm of snow. 10 to 15 km/h northeast ridgetop wind. Treeline temperatures -14 °C.

Monday

A mix of sun and cloud. 10 to 15 km/h northeast ridgetop wind. Treeline temperatures -20 °C.

Terrain and Travel Advice

  • Watch for signs of slab formation throughout the day.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.

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 Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
