During a night of clear skies a crust which is capable of bearing loads will form over widespread areas. As a consequence
of daytime warming and solar radiation this crust will thaw and the snowpack will subsequently forfeit its stability. Wet-snow
and gliding avalanches are possible. In the last few days very few wet-snow avalanches have been recorded, in spite of the
mild temperatures and sunny skies.
More than anywhere else in the inneralpine and the southern regions of Grisons, as well as in the southern Valais, there are
pronounced weak layers evident deeply embedded inside the snowpack. Moist and wet-snow avalanches in those regions can sweep
away these layers or be triggered by persons in some places. In isolated cases such releases have been observed in some places
in Grisons more than anywhere else.
The snowpack on north-facing slopes below approximately 1800 m, on east-facing below approximately 2500 m, on south-facing
slopes up to over 3000 m, and on west-facing slopes below approximately 2800 m, is thoroughly wet.
In general there is little snow on the ground, in the southern regions extraordinarily little. As a result of the thin, often
expansively metamorphosed (faceted) snowpack, there is heightened danger of falling into crevices on the glaciers, particularly
in the southern Valais.
