Graie Alps

Weakly bonded old snow at intermediate and high altitudes.

2 to 5 cm of snow, but less in some localities, fell on Tuesday above approximately 1200 m. Faceted weak layers exist in the bottom section of the snowpack on shady slopes. Sunshine and high temperatures gave rise on Monday to increasing consolidation of the snowpack in all aspects below approximately 3000 m. Especially sunny slopes as well as low and intermediate altitudes: The upper section of the snowpack is largely stable and its surface has a crust that is strong in many cases.

As a consequence of the new snow the avalanche prone locations will become more prevalent during the night.

Weakly bonded old snow at intermediate and high altitudes.

The wind slabs of last week are lying on the unfavourable surface of an old snowpack in particular on steep northwest, north and northeast facing slopes above approximately 1900 m. On steep shady slopes the avalanches can be released in deep layers of the snowpack and reach medium size, especially in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can in some places be released by small loads, but they will be small in most cases. Above approximately 1500 m snow will fall in the evening.
