Avalanche prone locations are to be found above approximately 2400 m.

Avalanche prone locations are to be found above approximately 2400 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, in particular in gullies and bowls, and behind abrupt changes in the terrain on very steep slopes. The avalanches can be triggered in the faceted old snow and reach medium size in isolated cases. As the temperature drops only isolated moist avalanches are possible.

Weak layers exist in the old snowpack on shady slopes. The snowpack is unfavourably layered and has a loosely bonded surface. Sunshine and high temperatures gave rise to increasing moistening of the snowpack on very steep sunny slopes below approximately 3000 m. These conditions will foster a gradual strengthening of the snowpack especially on very steep sunny slopes. 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.

Little snow will fall on Tuesday.
