Snowpack Structure

Snowpack

The fresh snow that has fallen over the last few days is still prone to triggering, especially on shady slopes in the high alpine regions. Most of it is located on the central part of the southern flank of the Alps and on the Main Alpine Ridge.

The old snowpack is water-saturated on southern slopes up to the high alpine regions, on eastern and western slopes up to around 3000 m, and on northern slopes up to a maximum of 2800 m. During the night, which is mostly clear, the moist snowpack stabilises. At high altitudes, the surface of the snowpack usually freezes solid, except on steep north-facing slopes. As the day progresses, the crust softens and wet avalanches are possible.

Weather Forecast

Outlook

In the west and south, the night into Monday will only be partly clear. During the day, it will often be cloudy and there will be showers and thunderstorms, especially in the afternoon. In the east it will be mostly clear during the night and quite sunny and mostly dry during the day. During the night into Tuesday, it will be mostly cloudy everywhere. On Tuesday it will often be cloudy with bright spells and showers, especially in the south. The zero-degree level will be between 2400 and 2800 m on both days, and the wind will be mostly light.

The risk of dry avalanches will slowly decrease. There are still avalanche prone locations for dry avalanches, especially on very steep north-facing slopes in the high alpine regions. The danger of wet avalanches will increase slightly as the temperature rises during the day.
