Snowpack

The large amounts of fresh and drifted snow which have fallen in the north are prone to triggering. In southern Valais, Grisons and Ticino, Friday’s snowdrift accumulations are still prone to triggering and weak layers still remain in the lower part of the snowpack. In these regions, avalanches may be triggered in drifted snow and sweep away deeper layers of the snowpack. Avalanches may occasionally also be triggered directly in deep snowpack layers.

Isolated gliding avalanches, sometimes large, are possible.

Weather forecast to Saturday

After a clear night, conditions will be sunny in the mountains.

Fresh snow

-

Temperature

At midday at 2000 m, between +2 °C in the west, -4 °C in the east and -2 °C in the south.

Mostly light, occasionally moderate from northerly directions

Weather review for Friday

There was widespread snowfall overnight, mainly in the north. The snowfall level fell rapidly from 1300 m down to low altitudes. During the day, a little snow continued to fall in the east, but in southern Valais and Ticino conditions brightened up from the west.

Fresh snow

From Thursday lunchtime to Friday afternoon:

• from the Wildstrubel via the eastern Bernese Oberland and the Urn Alps to the Glarus Alps: 30 to 50 cm.
• on the remaining northern flank of the Alps and in northern Valais: 20 to 30 cm.
• in the rest of Valais excluding the Upper Visp valleys and the Simplon region, in the rest of the Gotthard region and in northern Grisons: 10 to 20 cm.
• less elsewhere, dry in the far south

Temperature

At midday at 2000 m between -10° C in the north and -7 °C in the south

Wind

• Overnight in the north and in Valais moderate westerly, elsewhere light
• During the day on and to the south of the Main Alpine Ridge strong from the north, otherwise often moderate from northerly directions

Outlook

On Sunday there will some high broken cloud cover but conditions will be quite sunny in the Alps and the south. Conditions will will be mostly sunny on Monday. Winds will be light to moderate from westerly directions. The zero-degree level will be around 2000 m.

Avalanche danger will decrease, but only slowly in southern Valais, Ticino and Grisons due to the weak snowpack structure. Isolated gliding avalanches are expected.
