On the main Alpine ridge from the Great St Bernhard Pass to the Bernina Pass and to the south, large quantities of fresh snow
and a storm force southerly wind have given rise to extensive snow drift accumulations at elevated altitudes in recent days.
These remain prone to triggering in some cases. In the north, fresh snow and wind will give rise to further snow drift accumulations
over a wide area.
Below 2500 m, the snowpack has been weakened by heavy rain. With the ending of the precipitation and falling temperatures,
the wet avalanche activity will decrease. During Tuesday night, which will be cloudy, the moist surface of the snowpack at
intermediate and high altitudes will barely freeze. Individual wet snow and gliding avalanches remain possible.
