Regions

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

Snowpack depth and avalanche danger remain minimal.

If you manage to make it to the alpine and find any dry snow, the deepest, wind-loaded slopes would be the most likely to avalanche.

Confidence

Low

Avalanche Summary

With a limited early-season snowpack, there are not many reports from the backcountry. There have been no recent reports of avalanches.

If you head into the mountains, please share any observations or photos on the MIN.

Snowpack Summary

Another bout of heavy precipitation with high freezing levels will leave us with a soaked and shrinking snowpack everywhere other than the highest alpine terrain.

Snow depth varies rapidly with elevation. After this round of rain we expect there to be no snow below 1200 m, 40 cm at most just above tree line, and possibly small pockets of 80-100 cm in the high alpine.

Weather Summary

Tuesday Night
Cloudy. 15 to 45 mm of rain. 55-70 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level rising rapidly to 2700 m before falling again.

Wednesday
Cloudy. 15 to 25 mm of rain. 50-70 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 1900 m.

Thursday
Mostly cloudy. 2 to 3 mm of precipitation as snow or rain at treeline. 30 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1200 m.

Friday
Mostly cloudy. 4 to 10 mm of precipitation as snow or rain at treeline. 20 km/h west ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Wind slabs are isolated, but may remain reactive.

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.
