Regions

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

Sunny and hot conditions will weaken the upper snowpack.

Avoid travelling on or below steep slopes when the snow surface feels wet or slushy.

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been observed in the past couple days but observations are limited this time of year in the region.

Snowpack Summary

The snow surface will likely be moist or wet on all aspects and elevations as a result of elevated freezing levels Saturday night and further warming and solar input during the day on Sunday.

A thick crust can be found down 10 to 30 cm at treeline and above. The snowpack below this crust is well settled and strong.

At low elevations the snowpack is disappearing quickly. Where snow remains it is isothermal.

Weather Summary

Saturday Night
Cloudy. 1 to 2 mm of rain at treeline. 40 km/h south ridgetop wind. Treeline temperature 5 °C. Freezing level rising to 2600 m.

Sunday
Mostly sunny. 20 km/h south ridgetop wind. Treeline temperature 9 °C. Freezing level 2800 m.

Monday
Mix of sun and clouds. 2 mm of rain at treeline. 10 km/h south ridgetop wind. Treeline temperature 12 °C. Freezing level 2800 m.

Tuesday
Mostly cloudy. 2 to 5 mm of rain at treeline. 10 km/h south ridgetop wind. Treeline temperature 9 °C. Freezing level 2600 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Problems

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.
