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

New snow may form reactive slabs in wind affected terrain. Avoid freshly wind loaded slopes.

Step back into conservative terrain if you see more than 20 cm of snow over the day.

Confidence

Moderate

Avalanche Summary

Recent avalanches have been limited to size 1.5 slabs in wind affected terrain and loose dry sluff in sheltered areas.

We expect rider triggered avalanches to continue in wind affected terrain with snowfall expected Sunday night and throughout Monday.

Snowpack Summary

Low elevations received rain, or wet and heavy snow. Early season hazards (rocks, stumps and open creeks) are still present. The surface snow may have refrozen with a thick surface crust, or remain moist.

At higher elevations wind affected storm snow is settling rapidly over a thin and breakable rain crust. The mid and lower snowpack is well consolidated. Snow depth is between 125 cm and 250 cm at treeline.

Check out the North Shore avalanche conditions video here from December 27th.

Weather Summary

Sunday Night

Cloudy with 5 to 10 cm of snow. 10-20 km/h southerly ridgetop wind. Treeline temperature -3 °C. Freezing level 700 m.

MondayCloudy with 5 to 10 cm of new snow. Isolated areas may see up to 20 cm. 20 to 30 km/h southerly ridgetop wind. Treeline temperature -3 °C. Freezing level 700 m.

TuesdayCloudy with flurries. 20 to 30 km/h southeast ridgetop wind. Treeline temperature -3 °C. Freezing level 700 m.

WednesdayCloudy with flurries. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -3 °C. Freezing level 700 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.

Avalanche Problems

Wind Slabs

Reactivity is expected to continue on convex rolls, near ridgelines and on cross loaded slopes.

Aspects: North, North East, East, West, North West.
