Waadtländer Voralpen

In the east a considerable avalanche danger will be encountered in some regions.

As a consequence of easterly wind, sometimes avalanche prone wind slabs formed in the last few days. Single winter sport participants can release avalanches in some places, including medium-sized ones. Backcountry touring and other off-piste activities call for careful route selection.

Snowpack Winds from easterly directions have given rise to snow drift accumulations in recent days, in particular in the Jura, on the northern flank of the Alps and generally at elevated altitudes. They are to be found, in particular, in gullies and bowls and behind abrupt changes in terrain, and can still be released in some places. Faceted weak layers exist in deep layers of the snowpack, in particular on north facing slopes above approximately 2200 m and on south facing slopes above approximately 2800 m. In both southern Valais and Grisons in particular, these weak layers remain prone to triggering. In particular in the Vaud Alps and in Valais, isolated gliding avalanches can occur on steep, grassy slopes. Observed weather review Tuesday, 24.01.2023 In the mountains it was fairly sunny.

• On Tuesday night in Val Müstair: a few centimetres
• Elsewhere: dry

Temperature At midday at 2000 m: about -1 °C Wind Light, at elevated altitudes light to moderate, from the east Outlook through Friday, 27.01.2023 Above the low stratus, it will remain mostly sunny in the mountains. The northeasterly wind will be light to moderate at first, and then on Friday become moderate to strong in the Jura and the central and eastern parts of the main Alpine ridge in particular. On Friday the temperature will decrease appreciably again. The avalanche danger will not change significantly.
