Snowpack

Owing to the new fallen snow and strong westerly winds, fresh snowdrift accumulations are forming. These are deposited on a mostly compact, sometimes icy and slippery snowpack surface, which is characterised by the stormy weather, warmer temperatures and rain of the past week.

The snowpack structure is generally favourable. In the last few days, avalanches triggered by people have only been reported in isolated cases.

The gliding avalanche activity has decreased appreciably in the past few days. Nevertheless, medium-sized and occasionally large gliding avalanches are still possible.
