Waadtländer Voralpen

Snowpack

A lot of snow fell in the south last week, and this was deposited over a wide area on an irregular and therefore favourable old snow surface. However, there are angular layers in the area of the old snow surface that are prone to triggering in places, especially on north-facing slopes that are at a distance from ridgelines and sheltered from the wind.

In the north, wind slabs have formed in the last few days; they are still growing to some extent in some localities in the high Alpine regions. They are usually only thin, but sometimes prone to triggering.

Gliding avalanches are still possible. This applies particularly to east-, south- and west-facing slopes below approximately 2600 m and more rarely to north-facing slopes below approximately 2200 m. These avalanches may be large in some cases in regions with a lot of snow.

Weather forecast until Wednesday, 14.02.2024

Tuesday night into Wednesday will be overcast at times in the north and east and mostly clear elsewhere. During the day it will be fairly sunny with patches of cloud in the north and mostly sunny in the south.

Temperature

Temperatures will rise. At midday at 2000 m, it will be between +3 °C in the west and 0 °C in the east.

• There will be a weak to moderate westerly to northwesterly wind.
• In the high Alpine regions, there will be a moderate to sometimes strong northwesterly wind.

Weather review for Tuesday, 13.02.2024

Monday night into Tuesday was cloudy in the north and east, and little snow fell above approximately 1100 m. It was mostly sunny during the day.

New snow

On the northern flank of the Alps east of the Aare, Prättigau, up to 5 cm of fresh snow was recorded.

Temperature

At midday at 2000 m, -2 °C in the west and south, and -5 °C in the east.

Wind

There was a weak to moderate westerly to northwesterly wind.

Trend until Friday, 16.02.2024

On Thursday, it will be sunny at times and very mild. The zero-degree level will increase to over 3000 m. On Friday, in the north it will be mostly cloudy and largely dry until the afternoon. It will be sunny at times in the south. The zero-degree level will drop to 2600 m as the day progresses. There will be a weak to moderate westerly wind both days.

The danger of dry avalanches will decrease. Gliding avalanches are still possible, occasionally even large ones in regions with a lot of snow. As a consequence of warming and incoming radiation during the day, snow slides and avalanches are also possible, especially on steep south-facing slopes.
