Regions

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

Continue to manage small sluffs that could turn into a larger loose dry avalanche.

Even short windows of sun effect can turn steep south-facing slopes moist so pay attention to surface conditions if the sun starts to peak out.

Confidence

Moderate

Avalanche Summary

Several dry loose avalanches in steep unsupported terrain features have been reported across our region.

Snowpack Summary

Recent snow accumulated over the last week 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

Sunday Night

Cloudy with the possibility of convective flurries bringing up to 5 cm of new snow. Light easterly winds and treeline temperatures of -6 °C.

Monday

Mostly cloudy trace of new snow. Light southwest winds and treeline temperatures of -5 °C.

Tuesday

Mostly clear skies with no new snow expected. Light northerly winds and treeline temperatures of -3 °C.

Wednesday

Mainly clear skies, increasing clouds with no new snow. Light northerly winds with treeline temperatures of -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

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

Problems

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.
