As a result of small amounts of fresh snow and intermittently strong-velocity westerly winds, snowdrift accumulations have
been generated. These drifts are predominantly small-sized in most regions. In the west, where most of the snowfall has been
registered, they are somewhat larger-sized. The fresh snowdrift accumulations can be triggered on high-altitude north-facing
slopes more than anywhere else.
In the uppermost part of the old snowpack there is a weak layer evident in many regions. In the southern Valais, in Grisons
south of the Anterior Rhine and in the Gotthard region, isolated avalanches have been triggered by persons from this layer
over the last few days. These triggerings occurred particularly on west-facing, north-facing and east-facing slopes, in isolated
cases also on south-facing slopes.
During the nights of predominantly clear skies, the moist snowpack stablizes at intermediate altitudes. As a result of daytime
warming and solar radiation, moist snowslide can be expected during the course of the day. On very steep slopes, gliding snow
avalanches are possible.
