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

Unsettled conditions continue, with the potential for significant localized snowfall.

Verify conditions as you go and adjust terrain choices if you notice signs of instability.

Avalanche Summary

Small loose dry and storm slabs (size 1) were easily triggered by skiers on steep slopes near Grouse Mountain and Sky Pilot Mountain on Friday.

Thanks for sharing your observations via the MIN if you are going out into the backcountry.

Snowpack Summary

The region received another 20 to 25 cm of new snow this weekend, totaling 120 cm of recent storm snow, which is settling out rapidly. Unsettled conditions have brought up to 35 cm of new snow in localized areas.

At upper elevations, strong winds have formed deeper deposits of wind-transported snow. At treeline and below, the new snow sits above a crust. The snow reportedly has a good bond to the underlying crust.

Below this, the snowpack is well-settled and strong.

Weather Summary

Sunday Night

Cloudy with 10 to 15 cm of new snow. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 800 m.

Monday

Partly cloudy with isolated flurries. 30 to 40 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Tuesday

Mix of sun and clouds. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Wednesday

Partly cloudy with isolated flurries. 40 to 50 km/h southeast ridgetop wind. Treeline temperature 0 °C. Freezing level 1400 m.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.

Avalanche Problems

Storm Slabs

Additional overnight snowfall will contribute to reactive storm slabs. These slabs will be largest and most reactive on northerly slopes. Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
