Prone to triggering fresh wind slab.

Prone to triggering fresh wind slab.

The avalanche danger is moderate above 2400 metres and low below. Storms from the northwest have been depositing fresh wind slab snow on an unfavourably built-up old snow surface for several days. From around 2400 m, avalanches can be triggered by individuals in some places and occasionally become medium-sized. There is a risk of burial in particular near terrain traps, i.e. in areas adjacent to the ridgeline, crest or summit. The drift snow packs are usually easily recognisable.

The snow cover, snowpack is highly variable. On the surface, in leeward areas, there is a succession of fresh drift snow layers on the melt-freeze crust of the old snow surface. Fractures are most possible here, the drift snow layers are poorly connected to each other and to the melt-freeze crust in some places. Underneath, there is usually edgy snow with no binding. Due to the overall heavily built-up transformed snow cover, the potential for fracture propagation in the old snowpack is generally low. The snow depth is well below average at all altitudes.

The sun may still be out at the start of the day on Friday, but the weather will then increasingly deteriorate from the north. A little new fallen snow may fall during the daytime changes, but no more than 5 cm is expected. Short gaps of cloud may form from time to time. The wind will blow briskly from the west on the mountains at around 70 km/h at times. Temperatures will drop again, reaching around -8 degrees at 2000 metres and -13 degrees at 3000 metres.

No significant change in the avalanche danger on Saturday.
