Waadtländer Voralpen

Snowpack

Last week's fresh snow has largely settled. Dry slab avalanches are still possible, especially at high altitudes on steep north-facing slopes.

The old snowpack is water-saturated on southern slopes up to the high Alpine regions and on eastern and western slopes up to around 3000 m. On northern slopes, most of the old snowpack is water-saturated up to between 2600 and 2800 m. Wet avalanches, some very large, may still occur at these altitudes, because some weak layers deep in the snowpack are still dry and will become significantly less stable when they first become saturated. Such deep weak layers are particularly prevalent in the inneralpine regions.
