Stura Valley

At intermediate and high altitudes a considerable avalanche danger will persist.

At intermediate and high altitudes a considerable avalanche danger will persist.

The new snow can be released easily, or, in isolated cases, naturally in particular on steep shady slopes above the tree line. The avalanche prone locations are to be found in particular in steep terrain above approximately 1400 m and in gullies and bowls, and behind abrupt changes in the terrain. The avalanches can be released, even by a single winter sport participant and reach medium size. Additionally to some extent avalanches can also be triggered in the old snowpack and reach large size in particular in the regions neighbouring those that are subject to danger level 4 (high). 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. The current avalanche situation calls for caution and restraint.

20 to 40 cm of snow, and even more in some localities, fell on Tuesday above approximately 1300 m. The fresh snow as well as the wind slabs will be deposited on the unfavourable surface of an old snowpack in particular on shady slopes. Shady slopes: The old snowpack is faceted and weak.

At low and intermediate altitudes the avalanche danger will decrease sharply.
