Regions: Bonnington, Grohman, Kokanee, Kootenay Boundary, Kootenay Pass, Norns, North Okanagan, Rossland, South Okanagan, Valhalla, Ymir.

Continued high freezing levels and strong solar radiation could trigger wet slab avalanches on steep slopes.

This is our final daily forecast for the season.

Confidence

Moderate

Avalanche Summary

On Thursday, several naturally triggered wet loose avalanches up to size 1 were reported on steep solar aspects.

NOTE: Observations in this region are currently very limited.

Snowpack Summary

Freezing levels are expected to soar to near 3000 m over the next couple of days, with no cooling and poor crust recovery overnight.

All elevations will not refreeze and are experiencing an all-melt, no freeze scenario, and are melting out quickly.

Weather Summary

Friday Night

Clear skies. 5 to 10 km/h variable ridgetop wind. Treeline temperature 7 °C. Freezing level 2800 m.

Saturday

Mostly sunny. 5 to 10 km/h north ridgetop wind. Treeline temperature 9 °C. Freezing level 2900 m.

Sunday

Mostly sunny. 5 to 10 km/h northwest ridgetop wind. Treeline temperature 7 °C. Freezing level 2700 m.

Monday

Mix of sun and cloud. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Start your day early and be out of avalanche terrain during the heat of the day.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Triggering deep layers is more likely if the snow surface didn't freeze overnight.
  • Avoid thin areas like rocky outcrops where you're most likely to trigger avalanches on deep weak layers.

Avalanche Problems

Wet Slabs

Prolonged high freezing levels and intense sunshine could trigger large wet slab avalanches on steep slopes.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
