Surface hoar has also formed in many places over the past few days and has now been covered by fresh snowfall in the south. Avalanches can therefore easily be triggered at the transition between the fresh and old snow.</p><p>There are distinct weak layers in the middle and lower part of the snowpack, particularly on wind-protected shady slopes. Such places are particularly common south of a line from the Rhone to the Rhine. In these weak layers, people can still trigger medium-sized and, in isolated cases, large avalanches. The snowpack on northern and eastern slopes in central Valais, as well as in northern Grisons, is most prone to triggering while north of a line from the Rhone to the Rhine, the deeper layers of the snowpack are somewhat less prone to triggering and hazardous zones are less common there.</p>"}}}
