Regions: Harrison-Fraser, North Shore, Powell River, Sasquatch, South Coast, Stave, Tetrahedron.

Dangerous avalanche conditions exist in steep terrain where wet loose avalanches remain reactive to human triggering.

Minimize exposure to overhead hazard wherever possible.

Confidence

High

Avalanche Summary

No new avalanches were reported on Sunday.

On Saturday, loose wet avalanche activity, up to size 2, was concentrated to steep sun affected slopes in the heat of the day.

We expect natural solar-triggered wet loose avalanche activity and cornice failures to continue until temperatures return to below-freezing.

Snowpack Summary

The upper 30 to 60 cm of the snowpack is wet from prolonged warm temperatures and strong sunshine. Saturated snow is struggling to bond to a thin melt-freeze crust or the dry snow found below it.

The mid and lower snowpack is well settled and dense, however, buried crusts may make sliding surfaces for avalanche activity as the warming affects deeper into the snowpack.

Weather Summary

Monday Night

Clear skies. 10 km/h southwest ridgetop wind. Treeline temperature +8 °C with freezing level above 3000 m.

Tuesday

Sunny. 10 to 25 km/h southwest ridgetop wind. Treeline temperature +6 °C with freezing level dropping to 2500 m in the afternoon.

Wednesday

Mainly cloudy. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 0 °C with freezing level dropping to 1500 m in the afternoon.

Thursday

Cloudy with 1 to 2 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level hovers at 1500m.

Terrain and Travel Advice

  • Carefully manage your exposure to overhead hazards while entering and leaving riding areas.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches
  • Avoid exposure to slopes that have cornices overhead.
  • Large cornice falls are dangerous on their own.

Avalanche Problems

Loose Wet

Loose wet and wet slab avalanches are expected as warming continues, with no overnight cooling. Warming is amplified on sun affected slopes, particularly near rock outcrops.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2
