The moderate rating is due to an inversion and plenty of sunshine in the forecast for Monday. This could increase the avalanche danger on steep, sun-exposed terrain, particularly for ice climbers.

Overall, the snowpack is either wind-hammered or completely faceted.

Avalanche Summary

On Saturday, some small, loose, wet natural avalanches (sz. 1) were reported above the Bourgeau ice climbs near Sunshine ski hill, but they didn't reach the tops of the climbs. A few small, solar-triggered slides (size 1-1.5) were also seen today in the Lake Louise backcountry. These slides ran a couple hundred metres.

Snowpack Summary

There has been widespread wind effect down into treeline in exposed areas.

Where the wind hasn't had an impact, the surface is a mix of facets and/ or sun crust, depending on your location. Below this, the mid-pack consists primarily of facets.

At the base of the snowpack lies a widespread, weak layer of depth hoar and a crust. It is dormant for now but should not be forgotten.

Snow depths at the treeline range from 60 to 100 cm.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.

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.
