Danger level



Avalanches hardly possible

Weak layers can trigger in transitions,esp. on NW/N/NE facing slopes above 2000m, releases small, generally triggerable only by large additional loading.

Snowpack

Shady slopes above 2000m: in lower part of snowpack faceted weak layers.Very little snow on the ground.

Tendency

No significant change in avalanche danger levels expected


Danger level

Avalanche Problem
Persistent weak layer
1800m


Caution: snowdrifts and weak layers in old snowpack

Avalanches can be triggered by one sole skier in some places, particularly on shady wind-protected slopes in zones. Danger zones and likelihood of triggering tned to increase with ascending altitude. Avalanches can grow to medium size. In addition, in places avalanches can be triggered in the surface layers, releases usually small but easily triggerable. On extremely steep sunny slopes, increasingly frequent small moist loose-snow avalanches are possible. Isoalted mostly small glide-snow avalanches are possible.

Snowpack

dp.6: cold, loose snow and wind
dp.4: cold following warm / warm following cold

There was local snowfall. The SW winds transported the fresh snow. On shady slopes above 1800m: snowdrift accumulations are often poorly bonded with the old snowpack. In the lower part of the snowpack there are faceted expansively metamorphosed weak layers evident. On shady slopes below 1800m: weather conditions are consolidating the snowpack during the nocturnal hours. The fresh snow lies deposited atop a hardened crust. Extremely steep sunny slopes: solar radiation moistening the snowpack as of midday.

Tendency

Weak layers in the old snowpack still demand caution

Main danger: weak layers in old snowpack

Avalanches can be triggered even by one sole skier, esp. on shady wind-protected slopes. Isolated danger zones occur also on sunny slopes which are little skied on in high alpine terrain, in isolated cases releases can grow to large size. Remote triggerings are possible, particularly treacherous are the foot of rock walls. A defensive route selection is important. In addition, on wind-loaded slopes, surface layers can be triggered in some places, the releases mostly small but easily triggered. In the major areas of precipitation, isolated and mostly small glide-snow avalanches are possible.

Snowpack

dp.1: deep persistent weak layer

Shady wind-protected slopes above 2400m: in the lower part of the old snowpack there are faceted expansively metamorphosed weak layers evident. On shady slopes where the snow is rather shallow above 1800m: fresh snow and drifts blanket a weak old snowpack. Very sunny steep slopes below 2800m: the fresh snow lies atop a hardened crust. Sunshine moistens it

Tendency

Weak layers in the old snowpack still demand caution

Isolated danger zones occur on NW/N/NE facing slopes above 1800m

Due to fresh snow and SW winds, small snowdrift accumulations have been generated in gullies and bowls, but triggerable only in isolated cases. Isolated danger zones occuron NW/N/NE facing slopes above 1800m. On extremely steep sunny slopes, small moist loose-snow avalanches are possible.

Snowpack

dp.4: cold following warm / warm following cold

Freshly generated snowdrift accumulations lie deposited on NW/N/NE facing slopes above 1800m atop soft layers. Below 1600m there is hardly any snow on the ground.

Tendency

No significant change in avalanche danger levels anticipated
