Regions

South Okanagan, Shuswap, North Okanagan.

Localized danger may exist on steep slopes with wet snow.

Confidence

Moderate

Avalanche Summary

On Wednesday a few small wet loose avalanches were observed on sun-exposed slopes.

Looking forward, wet loose avalanches will become more likely as skies clear and the freezing level rises.

Snowpack Summary

5 to 10 cm of fresh snow on Thursday night will become wet with rising freezing levels and sun exposure. The upper snowpack consists of various melt-freeze layers and the lower snowpack is strong and bonded.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.

Problems

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.
