Outside marked and open pistes a high avalanche danger will still be encountered.

Outside marked and open pistes a high avalanche danger will still be encountered.

At intermediate and high altitudes a high avalanche danger will persist. The new snow can be released easily or naturally in particular on steep shady slopes above the tree line. Avalanches can in some cases be triggered in the old snowpack and reach large size. In the typical avalanche paths in the regions exposed to heavier precipitation the avalanches can reach fairly large size and in some places endanger transportation routes that are exposed. Single backcountry tourers can release avalanches easily, caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain. The current avalanche situation calls for great caution and restraint. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches are a clear indication of a weakly bonded snowpack.

Over a wide area 60 to 80 cm of snow, and even more in some localities, has fallen since yesterday above approximately 1400 m. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack on shady slopes at intermediate and high altitudes. Shady slopes: The old snowpack is faceted and weak.

From Thursday, the natural avalanche activity will appreciably decrease.
