Regions

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

Choose mellow slopes. An ongoing storm is increasing avalanche danger.

Check how much new snow you are finding over the crust. Snowfall amounts are expected to vary across the island.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.
  • We are uncertain about how the snowpack will react to the forecast weather.

Avalanche Summary

No recent avalanches have been reported, but the ongoing storm is expected to increase the likelihood of avalanches for Wednesday.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

Another 15 to 50 cm of new snow is expected to fall by the end of the day on Wednesday. This should fall on settling dry or moist snow in most places. Strong to extreme southwest winds overnight are expected to make deeper, more reactive slabs in leeward terrain.

RIght up to mountain tops, a widespread, thick and hard crust is now expected to be buried by 30-60 cm of snow.

The snowpack below the crust is strong and bonded with no layers of concern.

Weather Summary

Tuesday Night
Cloudy. 10 to 20 cm of snow, hotspots of 25 to 30 cm. 60 km/h southwest ridgetop wind, decreasing by the early morning. Treeline temperature -2 °C. Freezing level 900 m.

Wednesday
Mostly cloudy. 5 to 10 cm of snow, hotspots of 15-20cm. 25-45 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Thursday
Mostly cloudy. 4 to 20 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Friday
Mostly cloudy. 3 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
