Regions

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

Storm slabs will increase in size and sensitivity as the day goes on.

Choose conservative terrain until the storm snow has time to settle.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.
  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

No avalanches have been reported recently. Avalanche activity will increase with the forecasted weather.

If you get out into the backcountry, post a MIN!

Snowpack Summary

20 to 45 mm of precipitation is expected by the end of the forecast period on Tuesday, with the highest amounts in the western part of the region. Freezing levels will be around 1000 m, which means the mountains will receive a hefty dose of fresh snow. This new snow falls on a melt-freeze crust, moist snow, or isothermal conditions, depending on aspect and elevation.

Little change is expected at lower elevations. Watch for slushy, isothermal conditions—these can make travel difficult and increase the likelihood of wet loose avalanches.

Weather Summary

Monday Night

Cloudy. 2 to 5 mm of precipitation as snow or rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Tuesday

Cloudy. 20 to 40 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Wednesday

Mix of sun and clouds. 4 to 10 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -3 °C.

Thursday

Sunny. 20 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Don't let storm day fever lure you into consequential terrain.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
