Trend until Sunday, 05.05.2024

It will be changeable with showers on both days. The zero-degree level will rise from 1500 to 2400 m. There will be southwesterly winds, with strong winds at times at high altitudes. The avalanche danger will continue to fall in the south, otherwise it will not change significantly.

Snowpack

On and to the south of the Main Alpine Ridge, new and drift snow are still prone to triggering at high altitudes. In the other regions, the surface of the snowpack at high altitudes is hard and characterised by this week’s mild temperatures and strong southerly winds in many places.

The old snowpack has become soaked up to over 3000 m on east-, south- and west-facing slopes and up to around 2500 m on north-facing slopes. Particularly in the inneralpine regions, wet slab avalanches, including large ones, are possible on north-facing slopes as the moistening process progresses again.

Gliding avalanches are still possible, increasingly so once again at high altitudes.
