Regions

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

Snow is on the way as freezing levels finally drop!

Watch for rapid loading on steep alpine slopes.

Confidence

Moderate

Avalanche Summary

With the thin early-season snowpack, there are few backcountry reports and no recent avalanche observations.

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

Snowpack Summary

Freezing levels are finally dropping, with snow reaching treeline Monday night into Tuesday. A brief rise to around 1600 m Tuesday afternoon may bring some rain, leaving 10 to 30 cm of wet new snow. Cooler temperatures and more consistent snowfall are expected in the following days.

This new snow is falling on a very thin base: just 20 to 50 cm of rain-soaked snow above 1000 m and bare ground below.

The shallow snowpack has made for challenging travel and access to most skiing/riding areas.

Weather Summary

Monday Night
Mostly cloudy. 5 to 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

Tuesday
Cloudy. Mixed precipitation with 10 to 30 cm of snow at treeline elevations before freezing levels rise and another 5 to 15 mm of rain falls. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 1600 m.

Wednesday
Mostly cloudy. 15 to 30 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1100 m.

Thursday
Mostly cloudy. 15 to 30 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1200 m.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Dial back your terrain choices if you are seeing more than 30 cm of new snow.

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.
