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. Caution urged below glide cracks.
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 there is usually a breakable crust up to intermediate altitudes. 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. S will be very dry, radiantly sunny. Above the inversion it is mild, with only light winds. At 2000m: 0 to +6 degrees. Mostly light winds.
Avalanche danger levels will continue to decrease. Especially glide-snow avalanches still possible.
