Avalanche Activity

In regions exposed to heavier precipitation the avalanche prone locations are more prevalent.

As a consequence of new snow and a moderate to strong southerly wind, precarious wind slabs will form on Tuesday in the regions exposed to heavier precipitation. These will be deposited on weak layers in particular on shady slopes. The avalanches can be triggered in the faceted old snow. Sometimes they are medium-sized and can be released in some cases even by a single winter sport participant, in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example on very steep slopes.

Snowpack Structure

In particular on the southern flank of the Alps 10 to 25 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 rising temperatures and solar radiation a crust formed on the surface at the weekend. At low and intermediate altitudes only a little snow is now lying. The numerous rocks hidden by the recent snow are the main danger.

Tendency

On Wednesday it will be mostly sunny.
