Waadtländer Voralpen

Snowpack

The new snow and snowdrift were deposited on a very variable snowpack in the north. Particularly in places that are protected from the wind, the old snow surface had become faceted or there was surface hoar (hoar frost). The avalanche danger will decrease only slowly in these places. Adjacent to ridgelines, the old snowpack was strongly influenced by the wind and irregular. The connection between the new snow and snowdrift and the old snowpack should be better there. There is only a little snow on the southern flank of the Alps and in southern Grisons.

In the central part of the snowpack, the Northern Alpine Ridge, Valais, the Gotthard region, northern and central Grisons and Engadine have some weak layers in the area of melt-freeze crusts.
