Snowpack Structure

Snowpack

Over the last few days, 10 to 20 cm of snow have fallen on the Main Alpine Ridge from Ticino to the Bernina region. The snowfall level has been around 2800 m. Moderate winds from the south have transported the new fallen snow to the northern slopes. With intense precipitation during the night to Sunday, further, sometimes extensive, snowdrift accumulations will develop in the south.

Above approximately 3000 m, new snow and drifted snow will be deposited on top of a cohesive old snowpack. There will be wintry conditions in the high Alpine regions.

Tendency

Trend

Monday and Tuesday will be mostly sunny and mild. The zero-degree level will be around 3300 m. The winds will be mostly light.

The danger of dry avalanches will decrease in areas with new fallen snow, but only slowly on very steep north-facing slopes in the high Alpine regions. In places, human activity may trigger avalanches and these could be significant on the Upper Valais Main Alpine Ridge. Alpine tours will require experience in assessing avalanche danger.

As a result of sunshine and warming, wet loose snow avalanches are to be expected in high Alpine regions with plenty of fresh snow.
