In Grisons a considerable avalanche danger will persist in some regions.

The somewhat older wind slabs can still be released in some cases. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls. The wind slabs are to be evaluated with care and prudence in steep terrain.

Snowpack At the weekend and on Monday, wind from easterly directions gave rise to snow drift accumulations in the Prealps and generally at elevated altitudes. In the Prealps and northern Grisons these have been covered by more recent snow in some cases and are therefore difficult to recognise sometimes in these regions. In some places these snow drift accumulations can still be released as avalanches. 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 Monday, 23.01.2023 The night was partly clear. During the day it was mostly very cloudy. A little snow fell in the Monte Rosa region, Lower Engadine and Val Müstair. Fresh snow

• Monte Rosa region, Lower Engadine south of the Inn, Val Müstair: a few centimetres
• Elsewhere: dry

Temperature At midday at 2000 m: about -4 °C Wind During the day in the Prealps and the high Alpine regions, strong at times, otherwise light to moderate from the northeast to east Weather forecast through Tuesday, 24.01.2023 After a partly clear night, during the day it will be quite sunny in the mountains. In particular in the far east, it will be partly cloudy. Some snow may fall in the southern Visp valleys, the Simplon region and Lower Engadine. In the Jura and on the northern flank of the Alps there will be low stratus cloud cover with an upper limit of 1300 to 1800 m. Fresh snow

• Southern Visp valleys; Simplon region, Lower Engadine south of the Inn, Val Müstair: 5 to 10 cm
• Elsewhere: mostly dry

Temperature At midday at 2000 m: about -3 °C Wind During the night at elevated altitudes, moderate from the east to southeast, otherwise mostly light Outlook through Thursday, 26.01.2023 The weather in the mountains will be mostly sunny. In the Jura and the Prealps there will be low stratus cloud cover with an upper limit of approximately 1500 m. The avalanche danger will decrease slowly.
