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.

Snowpack

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.

Tendency

Avalanche danger levels will continue to decrease. Especially glide-snow avalanches still possible.

Often favorable conditions apart from weak layers in old snow

Danger zones occur particularly in shady steep terrain where the snow is shallow and in transitions from shallow to deep snow. Caution: these spots are not recognizable. Glide cracks and settling noises are signals of danger. If avalanches fracture down to deeper layers of the snowpack they can grow to large size. On steep grassy slopes, and on sunny slopes in general, but increasingly frequently also on shady slopes, small-to-medium glide-snow avalanches are possible.

Snowpack

The fresh fallen snow and fresh drifts from the most recent period of precipitation have settled further and consolidated increasingly. On shady slopes it is still mostly loose, on sunny slopes a crust has often formed. On high mostly shady slopes, weak layers are evident inside the old snowpack which avalanches can trigger down to. Snowpack analysis and observations of fractures and isolated artificial triggerings corroborate this.

Tendency

Sunny and mild in the mountains, avalanche danger levels not expected to change significantly

Avalanche danger is low. Some danger zones occur on extremely steep shady slopes. Apart from the danger of being buried in snow masses, the risks of being forced to take a fall require consideration. On steep grassy slopes where there is sufficient snow on the ground, small glide-snow avalanches are possible.

Snowpack

The large amounts of fresh fallen snow and drifts from the most recent bout of precipitation have been able to settle and consolidate. On shady slopes the snow is generally still loosely-packed, on sunny slopes a melt-freeze crust has formed. At high altitudes on shady slopes in particular, the uppermost layers of the snowpack are weak, making them often prone to triggering.

Tendency

Avalanche danger levels not expected to change significantly
