Snowpack

In recent days, Bise and northerly winds have led to the formation of snowdrift accumulations in the Prealps and in the south. Otherwise, the new snow of recent days has remained so loose in many places that it was moved by the locally moderate southerly wind during Monday night into Tuesday. These fresh accumulations are fairly small, but have been prone to triggering.

On the central part of the southern flank of the Alps and in southern Upper Engadine, the old snowpack structure has been partially transformed, especially in places with little snow, and fractures deeper in the snowpack are possible in isolated cases. In the other regions, the bottom and middle sections of the snowpack are generally favourable, meaning that avalanches usually only involve the upper layers.

Isolated medium-sized and occasionally large gliding avalanches are still possible, especially at altitudes between 2000 and 2500 m.

Weather forecast for Wednesday, 10.01.2024

It will be a cloudy night for the most part and in the Jura and in the south there will be a small amount of snowfall down to low altitudes. During the day it will remain cloudy in the west, while in the east it will be fairly sunny. There will be clear spells in the mountains in the south.

New snow

In the Jura, as well as on the Main Alpine Ridge from Val Ferret to the Bernina and south of this, up to 5 cm of new snow is expected to fall.

Temperature

At midday at 2000 m, between -3 °C in the north and -6 °C in the south

Wind

On the Northern Alpine Ridge and the Main Alpine Ridge, there will be moderate southerly winds at times; otherwise winds will be weak.

Weather review for Tuesday, 09.01.2024

In the east there were a few clear spells in the mountains; elsewhere it was cloudy but mainly dry.

New snow

Temperature

At midday at 2000 m, between -8 °C in the Prealps and -3 °C in the south.

Wind

In the regions exposed to the foehn wind in the north, on the Northern Alpine Ridge and in the Jura, there will be moderate southerly winds; they will be mostly weak elsewhere.

Trend until Friday, 12.01.2024

In the mountains it will be sunny and slightly less cold. There will be a Bise wind in the Prealps and the Jura, and weak to moderate easterly to northeasterly winds at high altitudes.

The danger of dry avalanches will decrease. Individual gliding avalanches, mostly of medium size, will still be possible.
