Regions: Bonnington, Grohman, Kootenay Boundary, Kootenay Pass, Moyie, Norns, Rossland, South Okanagan, Ymir.

The recent snow might not bond well. In areas that recieved more than 20 cm small storm slabs could be triggered.

Confidence

High

Avalanche Summary

Numerous wet loose avalanches were reported during the sunny period earlier this week.

We expect that in localized areas that recently received more than 20 cm of new snow rider triggerable storm slabs could be found.

Snowpack Summary

Up to 20 cm of new snow overlies a crust on all terrain except north facing slopes treeline and above. On these high northerly slopes new snow overlies facets and surface hoar to mountain tops.

The mid pack is generally well settled.

The lower snowpack includes a layer of weak sugary facets near the ground. These facets are slowly gaining strength and no recent avalanches have been reported on this layer. However, we continue to track the layer and watch for any signs of it becoming active.

Weather Summary

Friday Night

Mostly Cloudy with light flurries bringing a few centimeters of new snow. Light westerly winds and a low of -8°C at 1800 m.

Saturday

Mostly cloudy with the possibility of convective flurries bringing up to 5 cm of new snow. Light westerly winds and a high of -2°C at 1800 m. Freezing level rising to 1400 m.

Sunday

A mix of sun and cloud with the possibility of flurries bringing a few centimeters of new snow. Light easterly winds and Freezing levels rising to 1800 m.

Monday

Mostly cloudy with up to 10 cm of new snow possible at higher elevations. Light southerly winds and freezing levels rising to 1700 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.

Avalanche Problems

Storm Slabs

Rider triggerable storm slabs may still be found in areas where recent snow overlies surface hoar or a smooth crust. In areas that recieved less than 20 cm of new snow a dry loose avalanche problem is more likely.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
