Despite the high air temperature, the dry air means that the surface of the snowpack will freeze during the clear night into Saturday to become capable of bearing loads. Sunshine will cause it to soften quickly.

Moisture penetration into the snowpack is well advanced. The most precarious areas are slopes where weak layers in the old snowpack are becoming wet for the first time. At present, this mainly affects north-facing slopes between approximately 2200 and 2500 m, and east- and west-facing slopes between approximately 2500 and 2800 m. On south-facing slopes, moisture penetration into the snowpack extends as far as the high alpine regions. In Grisons, the weak layers in the old snowpack are the least deeply buried, which means that wet slab avalanches can also be triggered by human activity in some places.

Higher up, the snowpack is still dry. There are still weak layers in the old snowpack.

In general, hardly any avalanches have been reported in recent days.

After a clear night, conditions were sunny and mild.

Fresh snow

Temperature

At midday at 2000 m, between +7 °C in the north and +11 °C in the south

The zero-degree level was between 3300 m and 3500 m.

Wind

Light to moderate northeasterly

After a clear night, it will be sunny, with a few cumulus clouds developing during the course of the day. With the zero-degree level at around 3000 m, it will remain mild.

Fresh snow

Temperature

At midday at 2000 m, between +7 °C in the north and +9 °C in the south

Wind

Light to moderate from north to northwest

The night into Sunday will be mostly clear, and it will be sunny during the day with high cloud cover at times. The night into Monday will be mostly clear in the north, and only partly clear in the south. On Monday it will be mostly sunny in the north and partly sunny in the south with increasing high cloud cover. A few cumulus clouds will develop during the course of each day. In the far south, isolated showers are possible during the course of Monday. The zero-degree level will be around 3000 m. The winds will be light, at times rising to moderate from northerly directions as the day progresses.

After a clear night, touring conditions will be favourable in the early morning. The danger of wet avalanches will increase appreciably as each day progresses; where there is reduced outgoing longwave radiation during the night, this will occur in the early morning. Tours and hut ascents should therefore be started early and finished in good time.
