Mendrisiotto — Avalanche Forecast

SnowpackOver the last few days there has been heavy snowfall in the north, which in particular at the start was transported by strong to storm-force winds. In the south, the sometimes storm-force northerly wind has primarily transported loose old snow.On shady slopes sheltered from the wind in particular, the fresh and drifted snow is overlying weak layers and also buried surface hoar in the upper part of the old snowpack. Saturday saw avalanches triggered in these weak layers by winter sports participants. In the inneralpine regions of Valais and especially Grisons, the snowpack remains weak, and there is a possibility of isolated avalanches releasing even in near-ground weak layers.With fresh snow and wind, further mostly small snowdrift accumulations will form on Sunday in the north.
