The precipitation, which is heavy in some places, will continue into the night on Wednesday in the western regions and in
the Valais, in the northern and eastern regions until Thursday. The snowfall level lies at 2500 m, in some places in the western
regions even higher during the night.
As a consequence of strong to stormy westerly to northwesterly winds the new snow was intensively transported at high altitudes.
On Thursday, snowdrift accumulations will continue being generated in high alpine regions more than anywhere else as a result
of strong-velocity northwesterly winds. New snow and freshly generated snowdrift accumulations are prone to triggering, on
west-facing, north-facing and east-facing slopes particularly so. Dry-snow avalanches can fracture to deeper down layers in
the weak old snow. This applies to the regions from central Valais over the Ticino as far as Grisons more than anywhere else.
As a result of the persistent rainfall during Wednesday night, the snowpack in the western and the northern regions will become
even more thoroughly wet at high altitudes. Numerous and to an increasingly extent also large-sized avalanches can be expected.
