Slight daytime changes.

The avalanche danger increases from low to moderate during the daytime changes above 2500 metres. In a few places in the terrain, wet avalanches can occur spontaneously or be triggered by winter sports. Avalanches usually remain small, but can occasionally tear through the wet snow to the ground and reach medium size. Above around 2500 m, there are isolated avalanche prone locations in the extended northern sector where medium-sized slab avalanches can be triggered in persistent weak layers. Take care on the steep transitions from little to more snow.

The snowpack can outgoing longwave radiation overnight. A melt-freeze crust forms, which softens during the day. A few centimetres of new fallen snow can be found above around 2800 metres. The snowpack below consists of compact snow that is characterised by rain up to high altitudes. On shady slopes above around 2500 metres, there are still weak layers of angular shapes and deep rime in the old snowpack close to the ground.

The clouds will soon decrease on Thursday night and clear skies will prevail everywhere. Excellent visibility and clear sunshine on Thursday. The air will be very dry. On the northern edge of the Alps, cool north-easterly winds will be noticeable in places and moderate winds from north to east will also occur high up in the Alps during the day. At 2000 m -2 to +4 degrees with warmer air in the south, at 3000 m around -5 degrees.

Slight daytime changes after a clear, relatively cold night.
