On the northern flank of the Alps the bonding of the snowpack is favourable over a wide area. Stability tests (rutschblock and ECT) have triggered fractures in a weak layer lying either on top of or underneath the rain crust that formed at the end of December, in particular upon application of a medium to large additional load. From central Valais through northern Ticino to Grisons, weak layers exist deeper in the snowpack. Individual stability tests have continued to trigger fractures in these layers. For some time now, however, hardly any avalanche releases have been reported in this deep old snow.
At elevated altitudes, a northwesterly wind will transport sometimes loosely bonded old snow, and snow drift accumulations will form locally. These will be found in gullies and bowls in particular; in most cases they will be small.

During the night and on Monday morning in the east it was partly overcast and a little snow fell, even at low altitudes. In the afternoon it became increasingly sunny. In the west it was clear during the night and sunny during the day. The south was partly sunny.

On Monday night it will remain partly cloudy in the northeast, but the skies will be clear elsewhere. During the day it will be sunny over a wide area.
