Regions: East Island, North Island, South Island, Vancouver Island, West Island.

Fresh storm slabs have formed at upper elevations. Use caution on wind-loaded slopes near ridge top.

Confidence

Moderate

Avalanche Summary

A size 1 storm slab was reported near Mt Cain on Monday.

Pin wheeling and small point releases were also observed.

Observations are currently very limited in the region. If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

At upper elevations, 10-30 cm of storm snow overlies a crust. Thicker deposits may exist on northern aspects near ridge top, especially on the West Island. At lower elevations, the snowpack is rain-soaked or moist.

The snowpack is strong and well-bonded, but melting out quickly at lower elevations.

Weather Summary

Tuesday Night

Cloudy with 2-5 cm snow, possible rain below 1000 m. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

Wednesday

Mostly cloudy with 1-3 cm snow, possible rain below 1300 m. 30 to 40 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1300 m.

Thursday

Cloudy with 20 to 40 mm of heavy rain, possible snow above 1500 m. Highest accumulation on the West Island. 60 to 80 km/h south ridgetop wind. Treeline temperature 2 °C. Freezing level rising to 1600 m.

Friday

Cloudy with 2-8 cm snow above 1300 m, possible rain below. Highest amounts forecast for the West Island. 10 to 25 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level rising to 1300 m.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Avalanche Problems

Storm Slabs

Storm slabs are expected to be most reactive in wind-affected terrain at upper elevations.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Wet loose avalanches will be possible when the snow surface is wet or moist. Use good sluff management techniques.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
