This week's fresh and drifted snow is gradually settling and consolidating. In the upper part of the old snowpack, there are some faceted weak layers and some snow-covered surface hoar, particularly on wind-protected shady slopes. On Saturday in particular, avalanches were triggered in these weak layers by winter sports participants. In the inneralpine regions of Valais and especially Grisons, the snowpack structure remains weak, and there is a possibility of isolated avalanches starting even in near-ground weak layers.
With light snowfall and northerly winds, mostly small snowdrift accumulations formed on Sunday, especially on the northern flank of the Alps. These will continue to grow during the course of Monday in all regions.

From Monday afternoon to Wednesday afternoon, 50 to 80 cm of snow will fall on the northern flank of the Alps from the eastern Bernese Alps to the Glarus Alps and in Grisons north of the Anterior Rhine. 30 to 50 cm will fall on the rest of the eastern part of the northern flank of the Alps and in the rest of northern and central Grisons. There will be 10 to 30 cm of snow elsewhere. It will remain largely dry south of the Main Alpine Ridge. At high altitudes, the wind will be strong to stormy from northerly directions and will transport the fresh snow as well as loose old snow. In the south, there will be a sometimes strong foehn wind. Over the course of Wednesday, the wind will ease at high altitudes and a strong Bise wind will rise in the Jura.
In the north, the avalanche danger will increase significantly during the night into Tuesday across a wide area. On Tuesday, the avalanche danger is expected to reach danger level 4 (high) in the regions exposed to heavier precipitation on the northern flank of the Alps and in northern Grisons, with naturally triggered avalanches to be increasingly expected. These may be very large on the northern flank of the Alps and exposed parts of transportation routes may be in danger. In northern Grisons, the danger will primarily affect alpine snow sports terrain. Naturally triggered avalanche activity will decrease during the course of Wednesday. However, the situation will remain very critical for snow sports outside marked and open pistes.
The avalanche danger will increase somewhat in places in the south on Tuesday, and will not change significantly on Wednesday.
