New snow and freshly generated snowdrifts from the last couple of days were deposited on top of an old snowpack surface which
shows striking effects of rain, wind and sun, in some places is also iced-over. On Wednesday the snowdrift accumulations were
easily triggered in some places.
In addition, from the central Valais over the northern Ticino as far as Grisons more than anywhere else, avalanches can also
trigger from the old snowpack in isolated cases. This applies to the expansively metamorphosed (faceted), loose layers which
are located either immediately beneath the rain-crust which formed at the end of December or are found more deeply embedded
inside the snowpack.
