Regions

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

Observations are very limited so don't let your guard down.

Triggerable wind slabs may still exist in alpine terrain.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in the past few days, but field observations are limited.

If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.

Snowpack Summary

Up to 30 cm of recent snow up high overlies a crust. Down low it likely fell as rain and thickened the surface crust.

Snow depths at treeline vary across the region from 230 cm near Mt. Washington to 130 cm near Mt Cain.

Weather Summary

Tuesday Night

Mostly cloudy. 10 km/h south ridgetop wind. Treeline temperature 3 °C.

Wednesday

Mostly cloudy. 40 km/h south ridgetop wind. Treeline temperature 0 °C.

Thursday

Cloudy with up to 5 cm of snow. 20 to 30 km/h west ridgetop wind. Treeline temperature 0 °C.

Friday

Cloudy with 10 to 20 cm of snow. 30 km/h east ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Wind slabs are isolated, but may remain reactive.
  • Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
