Avalanche prone locations are to be found above approximately 2300 m.

Avalanche prone locations are to be found above approximately 2300 m.

In the course of the day the wind slabs will increase in size moderately. These will be deposited on weak layers in particular on shady slopes. The fresh wind slabs can be released, even by small loads in isolated cases. They must be evaluated with care and prudence. The avalanche prone locations for dry avalanches are to be found in areas where the snow cover is rather shallow and at transitions into gullies and bowls. The avalanches can be triggered in the faceted old snow and reach medium size.

2 to 10 cm of snow will fall on Tuesday above approximately 1600 m. Weak layers exist in the old snowpack on shady slopes. The snowpack is unfavourably layered and has a loosely bonded surface. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. As a consequence of highly fluctuating temperatures and rain up to approximately 2300 m a crust formed on the surface. The numerous rocks hidden by the recent snow are the main danger.

On Wednesday it will be mostly sunny.
