In sintesi

Avalanche Activity

Light snowfall to below 600 m. As the day progresses as a consequence of new snow and wind there will be an increase in the danger of dry avalanches within the current danger level.

In particular in the Prealps some new snow to low altitudes. This snow is bonding only slowly with the old snowpack above approximately 2300 m. As a consequence of new snow and a sometimes moderate wind, small wind slabs will form. These are to be evaluated with care and prudence in particular in terrain where there is a danger of falling. If more snow falls danger level 2 (moderate) may be reached in the course of the day. Adjacent to ridgelines and in gullies and bowls the danger of dry avalanches is a little higher. The avalanche danger should be investigated very thoroughly in the relevant locality. Weak layers in the old snowpack can still be released in very isolated cases by winter sport participants.

Snowpack Structure

The new snow is lying on a crust in all aspects above approximately 2300 m. In all regions only a little snow is now lying. The old snowpack is faceted. Faceted weak layers exist in the old snowpack in particular on shady slopes. This applies in particular above approximately 2300 m.

Tendency

Monday: Increase in danger of dry avalanches as a consequence of new snow and wind. In places where more snow falls danger level 2 (moderate) will be reached.
