Snowpack

There has been considerable snowfall on the Main Alpine Ridge and to the south of there over the past week. Especially on shady slopes, this snow is lying on an unfavourable, faceted old snow surface where it is sometimes prone to triggering. North of the Main Alpine Ridge, fresh and drifted snow layers are appreciably thinner.

In Valais, Ticino and Grisons, deep layers of the snowpack are also loose and faceted. Especially in Grisons, avalanches may reach down into deep layers of snowpack on shady slopes.

Individual gliding avalanches are possible.
