Persistent weak layers· Mattina
- Above 2,200 m
In the course of the day possibly danger level 4 (high) will be reached in the regions exposed to heavier precipitation. The danger exists primarily in alpine snow sports terrain.
In the course of the day possibly danger level 4 (high) will be reached in the regions exposed to heavier precipitation. The danger exists primarily in alpine snow sports terrain.
Significant increase in avalanche danger as a consequence of new snow and strong wind. Outside marked and open pistes a precarious avalanche situation will be encountered in some regions. Late morning: Even single winter sport participants can release avalanches easily, in particular on steep west, north and east facing slopes above approximately 2200 m. Caution is to be exercised in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. In some cases the avalanches are medium-sized. Afternoon: As a consequence of new snow and strong wind natural avalanches are possible as the day progresses. This applies in all aspects at high altitudes and in high Alpine regions. Avalanches can penetrate deep layers and reach large size in isolated cases, especially on very steep shady slopes above approximately 2200 m. As a consequence of the rain a large number of moist and wet snow slides are to be expected. Great caution and restraint are required.
In particular in the north and in the west over a wide area 20 to 50 cm of snow, and even more in some localities, will fall above approximately 2200 m. As a consequence of new snow and a sometimes storm force wind from northwesterly directions, extensive wind slabs will form. These will be deposited on a weakly bonded old snowpack in particular on west to north to east facing aspects above approximately 2200 m. The various wind slabs have bonded poorly together. The rain will give rise to gradual and thorough wetting of the snowpack over a wide area below approximately 2000 m.
On Saturday as a consequence of new snow and strong wind there will be only a slight increase in the avalanche danger, in particular in the regions exposed to heavier precipitation.
