Regions: Birkenhead, Duffey, South Chilcotin, South Coast Inland, 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.

Avalanche Problems

Storm Slabs

As new snow accumulates, storm slabs may form, especially in wind-affected areas. Slabs will likely be reactive as they are not expected to bond well to underlying surfaces.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2

Loose Dry

Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2
