Fresh snow and a sometimes strong northwesterly wind will give rise to snow drift accumulations that are prone to triggering on the northern flank of the Alps in particular and in the high Alpine regions in general. In addition, given the low temperatures, any weak layers will stabilise only slowly, so that the fresh snow and snow drift accumulations of recent days will also remain prone to triggering in the high Alpine regions in some cases. In some places, avalanches can release deeper layers of the snowpack. At elevated altitudes, conditions are more wintry than usual at this time of year.
The old snowpack is thoroughly moist below 2500 m on north facing slopes, and up to approximately 3000 m on east, south and west facing slopes. Both wet snow and gliding avalanches remain possible, in particular under the influence of solar radiation.

Night-time showers in the north moved away eastwards in the morning. During the day in the south it was mostly sunny, and in the north there was variable cloud with prolonged sunny spells.

The snowfall level was approximately 1600 m. From Monday afternoon until Tuesday morning, showers gave rise to the following amounts of snow above approximately 2000 m:

• Extreme west of Lower Valais, northern flank of the Alps, northern Prättigau to Samnaun: 5 to 10 cm
• Elsewhere: smaller amounts or none

At midday at 2000 m: between 0 °C in the north and +7 °C in the far south

From westerly directions

• During the night at elevated altitudes, remaining moderate to strong
• Easing during the day and mostly light in the afternoon

In the north, varying to large amounts of cloud with only brief bright spells and frequent showers will persist, in particular on the northern flank of the Alps. In some instances, thunderstorms are also possible. To the south of the main Alpine ridge it will be mostly sunny in the morning, but convective cloud will build up in the afternoon.

The snowfall level will be between 1300 and 1600 m. The following amounts of snow will fall above approximately 2000 m in the period from Tuesday until Wednesday afternoon:

• Northern flank of the Alps: 20 to 40 cm
• Lower Valais, northern Grisons: 10 to 20 cm
• Further south: mostly smaller amounts, and south of the main Alpine ridge remaining dry

At midday at 2000 m: between -2 °C in the north and +3 °C in the south

• In the north, moderate; at elevated altitudes, strong from the northwest, easing a little as the day progresses
• In the south, moderate to strong northerly in the mountains, with a north foehn reaching down into the valleys in some cases
