More moist snow slides and avalanches are possible. Little snow will fall from the afternoon.

The conditions in the morning are mostly favourable. From the afternoon the weather will be cloudy. Up to 1800 m and above rain will fall in particular in the Prealps. The danger of moist and wet avalanches will increase a little during the day. In particular on very steep slopes individual small and medium-sized moist and wet avalanches are possible as the moisture increases. Above approximately 1600 m snow will fall during the night in some regions.

Outgoing longwave radiation during the night was good. The surface of the snowpack has frozen to form a strong crust and will soften during the day. Below approximately 2800 m: The snowpack is fairly homogeneous and its surface has a melt-freeze crust. High altitudes shady slopes: The snowpack is dry. Adjacent to ridgelines at high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. As a consequence of mild temperatures and solar radiation the snowpack consolidated at the weekend. This applies in particular on steep sunny slopes at high altitude, and in all aspects at low and intermediate altitudes. Below approximately 2400 m only a little snow is lying on south facing slopes. In the last three days on very steep northwest, north and northeast facing slopes individual small and medium-sized avalanches were observed.

Wednesday: Some snow will fall in some localities. Down to 1700 m and below snow will fall until the early morning. The new snow is bonding poorly with the old snowpack in some places. The danger of moist snow slides and avalanches will already increase in the early morning, in the regions exposed to heavier precipitation in particular.
