Favorable conditions. Moderate avalanche danger.
Avalanche danger is moderate. In some places there are weak layers inside the snowpack which can be triggered by large additional loading. Small-to-medium sized avalanches are thereby possible. On steep grassy slopes and hillsides, especially on sunny slopes but increasingly frequently on shady slopes, small-to-medium glide-snow avalanches are possible. Due to solar radiation loose-snow slides and avalanches can be expected in rocky terrain.
The large amounts of fresh fallen snow and drifts from the most recent bout of precipitation have been able to settle slightly and consolidate. On the shady slopes the snowpack is still loosely-packed, on the sunny slopes it is soft but bonded. Weak layers inside the old snowpack are in places prone to triggering by large additional loading. At high altitudes, isolated older mostly compact snowdrift accumulations are evident.
Nocturnal skies will be star-studded, and thus, very cold. Friday will be cloudless and very mild in the mountains. At 2000m: 0 to +6 degrees. Mostly light NE winds.
No significant change in avalanche danger levels is anticipated. Glide-snow avalanches still possible.
