Snowpack stability is poor, especially in new snowdrift accumulations at typical locations - along ridges, in ravines, etc. Here, a small additional load can trigger a medium-sized avalanche.
Around 50 cm of snow fell over 1500 m at the weekend on a thin, old snow base, which was covered with a crust and had many cuts. Where the snow fell on hard, frozen ground, it did not bond well with it. It snowed with a strong southerly wind, especially near the ridges, causing snowdrift accumulations. The snowpack became heavier during the day on Monday and will freeze overnight.
Tuesday will be quite clear at first, clouding up quickly in the middle of the day. Highs will be foggy in the afternoon. A moderate south-westerly wind will blow. The temperature at 1500 m will be around -2 °C.
Showers will start to appear on Wednesday night. On Wednesday, we expect heavier showers with wind! The snowfall level will start at around 1300 m above altitudes, rising to 1900 m during the day. The danger of avalanches will increase temporarily due to rain.
