Regions

South Okanagan, Shuswap, North Okanagan.

Sun and a high freezing level will make wet avalanches the main concern on steep slopes facing the sun.

Confidence

Moderate

Avalanche Summary

A few small wet loose avalanches have been reported the past few days and more will occur when a mostly clear sky and the freezing level rises above mountain tops.

Snowpack Summary

Expect surfaces to melt and weaken as the freezing level climbs to 2600 m on Sunday. This will occur rapidly on sun-exposed slopes.

The upper snowpack consists of various melt-freeze layers and the lower snowpack is strong and bonded.

Weather Summary

Saturday Night

Mostly clear. 10-15 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level 2400 m.

Sunday

Sunny. 10 km/h southwest ridgetop wind. Treeline temperature +7 °C. Freezing level 2600 m.

Monday

Mix of sun and cloud. 15-30 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1800 m.

Tuesday

Mainly cloudy with isolated flurries. 20-30 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1600 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
