Snowpack Structure

Snowpack

Last weekend, 20 to 40 cm of snow fell in northern Grisons and a widespread 15 to 30 cm in the rest of Grisons and on the northern flank of the Alps. The snowfall level dropped to 1500 m at times.

Before the current precipitation event, the snow lines on the northern flank of the Alps and in northern Grisons were at 2000 to 2200 m, in Valais and other parts of Grisons at 2400 to 2800 m. A continuous snowpack, which already compensated for terrain irregularities, was mainly present in the glaciated high alpine regions.

Tendency

Trend for Thursday and Friday

In the north, snow will fall at times above approximately 1800 m. In the south, it will be mostly cloudy on Thursday and quite sunny on Friday with northerly winds.

The danger of dry avalanches in the high alpine regions will decrease only slowly. Below 3000 m, moist snow slides are possible in all regions with new fallen snow, especially on very steep grassy slopes.
