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

Stormy weather continues! Expect fresh, reactive storm slabs to form throughout the day.

Stick with a conservative trip plan and watch for signs of instability.

Avalanche Summary

With continuous storm cycles in the past week, numerous natural and human-triggered storm slab avalanches have been reported throughout the region.

Similar activity is expected on Saturday as stormy weather continues.

Snowpack Summary

Up to 30 cm of new snow by end of day Saturday brings the storm total from the past week to over a meter of new snow. At upper elevations, strong wind will 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

Friday Night

Increasing cloud cover. 5 to 20 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level 1100 m falling to 400 m.

Saturday

Cloudy with 15 to 25 cm of new snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -3 C. Freezing level 800 m.

Sunday

Cloudy with up to 5 cm of new snow. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 800 m.

Monday

Cloudy with 5 to 10 cm of new snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level rising to 1000 m.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.

Avalanche Problems

Storm Slabs

Reactive storm slabs are likely, especially on north-facing, wind-loaded slopes. Back off if you encounter signs of instability like whumpfing, shooting cracks or recent avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2.5
