Take into account persistent weak layers and avoid small-scale pillows of wind drifted snow

The avalanche risk is low. Medium-sized slab avalanches can still be triggered in a few hard-to-recognise places, especially in the extended northern sector above 1800 m, but usually only with a large additional load. This is in particular at the transitions from little to more snow. Fresh, small-scale pillows of wind drifted snow in areas adjacent to the ridgeline are temporarily prone to triggering.

The little new and wind slab snow lies in shady high altitudes on a soft, faceted snow surface. Otherwise, there is often a thin melt-freeze crust under the thin layer of new snow. Deeper in the snowpack, faceted crystals can be found on a crust; close to the ground, the snowpack consists of angular, cup-shaped crystals. The connection at the transition to the deep snowpack near the ground is still poor. Deep and sunny middle layers are largely snowed out.

During the night, the sky will initially be partly cloudy, with increasing cloud cover from the east after midnight. On Wednesday, dense clouds will initially often restrict visibility and it will snow at times. During the daytime changes, it will become somewhat friendlier, with better visibility and occasional sunshine. Strong east to north-easterly winds with gusts of around 70 km/h at high altitudes. Temperatures during the day changes to between -7 and -3 degrees at 2000 metres and between -12 and -9 degrees at 3000 metres.

No significant change in avalanche danger.
