Border Pennine Alps

As the precipitation becomes more intense the prevalence and size of the avalanche prone locations will increase from the early morning.

As the precipitation becomes more intense the prevalence and size of the avalanche prone locations will increase from the early morning.

In the regions exposed to heavier precipitation the prevalence and size of the avalanche prone locations will increase from the early morning. In particular on very steep slopes and in the regions exposed to heavier precipitation more frequent large and, in isolated cases, very large natural avalanches are to be expected as a consequence of the precipitation. Numerous large and, in isolated cases, very large moist and wet avalanches are to be expected as a consequence of the rain. Up to 1800 m rain will fall. This extends the avalanche runout distances. In many cases, the avalanches can reach the bare valleys from high-altitude starting zones. Individual weak layers exist in the old snowpack in particular at high altitudes and in high Alpine regions. Avalanches can in isolated cases be triggered in the old snowpack and reach quite a large size.

Over a wide area 80 to 100 cm of snow, and even more in some localities, will fall above approximately 2400 m. Up to 1800 m rain will fall until Thursday. Over a wide area new snow is lying on a moist old snowpack. The sleet will give rise to increasing moistening of the snowpack in particular at intermediate and high altitudes. Isolated avalanche prone weak layers exist in the snowpack at high altitudes and in high Alpine regions. Below approximately 2000 m a little snow is lying on southeast and southwest facing slopes.

Over a wide area persistent snowfall to intermediate altitudes: As the precipitation becomes more intense there will be an appreciable increase in the avalanche danger.
