Avalanche Activity

Generally low avalanche danger

Low avalanche danger in general, but attentiveness urged towards snowdrift patches in landscape concavities which are poorly bonded with the snowbase beneath them, in these danger zones isolated small slab avalanches can be triggered. In shady terrain above the timberline there is a persistent weak layer. Slab avalanches cannot be ruled out. Caution urged towards the peril of falling on icy surfaces.

Snowpack Structure

At high altitudes the surface is hardened and icy or wind-pressed, beneath that the fundament is compact and without avalanche-relevant weak layers. However, the process of expansive metamorphosis is continuing, the snowpack evidences increasingly frequently faceted crystals, is forfeiting its firmness and losing its hold.Above 1500 m on shady slopes the snowpack is metamorphosing expansively, the snowpack consists of more and more faceted crystals, it is forfeiting its firmness and losing its base.

Weather Synopsis

On Thursday night a warm front will cross the Eastern Alps and bring heavy cloud cover and a bit of precipitation to the northern flank of the Alps in particular on Christmas Eve. The southern flank of the Alps will enjoy more favourable conditions, south of the Main Tauern Ridge conditions will be far more pleasant, only high-altitude clouds and frequent sunshine particularly in the morning. Temperatures at midday: at 2000 m +4 degrees; at 1500 m +7 degrees. Also on Christmas Day, weather in the mountains will be cloudy. Winds will shift to southwesterly and slacken off. At 2000 m: 0 to 2 degrees. Hardly any precipitation, if at all, then in the afternoon near the Koralpe in the form of a few raindrops or snowflakes.

Tendency

Avalanche danger is expected to remain low.
