Snowpack

In the morning, on steep south-facing slopes there is often a supporting crust at the snowsurface up to high altitudes, while on west and east-facing slopes the surface often consists of a brittle melt-freeze crust. On north-facing slopes, the surface of the snowpack is still loose in places at high altitudes and sometimes shaped by the foehn wind of the last two days. The newer snowdrift accumulations are mostly small, but some are still prone to triggering.

Otherwise, the snowpack in the north is mostly well consolidated. In southern Valais, Ticino and Grisons, there are faceted, soft layers deeper in the snowpack. The snow layering in these regions is more unfavourable and avalanches can also very occasionally be triggered in deep layers of the snowpack.

As the day progresses, individual wet and gliding avalanches are possible.

Weather forecast to Saturday

Fresh snow

Temperature

At midday at 2000 m, between +3 °C in the north and -1 °C in the south.

Weather review for Friday

Conditions were sunny in the mountains.

Fresh snow

Temperature

At midday at 2000 m, around +1 °C.

Wind

Often moderate at high altitudes, occasionally strong from the south on the Northern Alpine Ridge

OutlookSunday

It will initially be sunny and mild in the north. As the day progresses, clouds will gather from the west. It will be cloudy in the south. Towards the evening, a few centimetres of snow will fall above 1500 m. There will be strong southerly winds at high altitudes and in the regions exposed to the foehn wind.

On the Northern Alpine Ridge, in Valais and in Grisons, snowdrift accumulations will form locally, especially on north-facing slopes. These represent the main danger. With fresh drifted snow at high altitudes and mild temperatures, the danger of dry and wet avalanches will increase somewhat in the north. In the south, the avalanche danger will hardly change.

Monday

It will be partly sunny in the north. In the south, snow will fall above 1500 m, especially during the night into Monday. On the Main Alpine Ridge and south of it, 10 to 20 cm of snow is expected over a wide area.

The avalanche danger will increase in the south with fresh snow, but will hardly change in the north.
