Avalanche Summary

On Thursday there were reports of several skier triggered size 1.5 wind slab avalanches in the alpine.

Snowpack Summary

Recently formed wind slabs in the alpine are bonding well to the underlying layers, but there might still be isolated pockets along ridge crests which can be triggered by humans (see the MIN report of our field team here). On higher north aspects above 2000 m new snow from early last week is gradually bonding with the dry, faceted [weak and sugary] snow underneath. In most other places surface snow is moist. Below 1800 m the entire snowpack is either moist or wet underneath a supportive melt/freeze crust.

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.
