During the daytime changes, the readiness to trigger wet avalanches increases rapidly.

During the daytime changes, the readiness to trigger wet avalanches increases rapidly.

There is a moderate avalanche danger from around 2200 m, below which it rises rapidly from low to moderate during the day. Damp and wet loose snow avalanches and snow slabs are to be expected during the day in all aspects. The avalanches can occur spontaneously or be triggered by winter sports enthusiasts. They usually remain small to medium-sized. Sliding snow avalanche activity is also to be expected on typical slopes. In a few places above 2200 m in the extended northern sector, weak layers in the persistent weak layer can also be addressed and the snow slabs can reach medium size.

The outgoing longwave radiation at night is good. A melt-freeze crust forms overnight, which quickly softens again during the day. Heat and moisture are increasingly penetrating the snowpack, with dry snow on the surface only at shady high altitudes. At medium altitudes, the snow cover is already wet down to the ground. On shady slopes from around 2200 metres upwards, the old snowpack contains angular shapes and deep rime. Fractures are most likely to occur in one of the uppermost crusts and only rarely in the floating snow near the ground. Some of the snow glides off the ground.

The night is starry. On Wednesday, the sun will mostly shine unclouded and there will be excellent visibility. During the daytime changes, there will be at most a few harmless spring clouds. Moderate to brisk north-westerly winds with gusts of around 40 km/h at higher altitudes. Temperatures at 2000 metres between 0 and 4 degrees, at 3000 metres around -2 degrees.

Little change.
