As a result of fresh snow and intermittently storm-strength westerly winds, the snowdrift accumulations will continue to grow
in frequency and size during Thursday night. In the western and the northern regions they will be large-sized in some places,
in the southern regions they will be small-to-medium sized. Fresh snow and freshly generated snowdrift accumulations are prone
to triggering, particularly on north-facing and east-facing slopes.
In Grisons and in the Valais more than anywhere else, weak layers are still evident in the ground-level old snow above approximately
2200 to 2400 m in all aspects. Avalanches are currently unlikely to trigger in these deeply embedded weak layers of the snowpack.
