Moderate avalanche danger due to freshly generated snowdrifts at high altitudes
The fundament is stable by and large. During the course of the day on Friday up to 20 cm of fresh snow is expected, the intensifying southerly winds will transport it to north-facing slopes. Moreover there are weak layers inside it.
Moderate avalanche danger due to freshly generated snowdrifts at high altitudes
Avalanche danger above the treeline is moderate, below that altitude danger is low. Danger zones occur where there are small freshly generated snowdrift accumulations in extended east-facing terrain: here in some spots a small-to-medium slab avalanche can be triggered by 1 person. In addition, naturally triggered wet-snow slides are possible in all aspects.
On Friday a low over Upper Italy will bring gray skies and wet weather, the peaks will be veiled in clouds, visibility poor, heavy rainfall/snowfall throughout Styria, snowfall level in the Northern Alps below 1000 m already in early morning, also in Niedere Tauern and southern ranges later in the day. By Friday evening in Gurktal and Seetal Alps and Niedere Tauern, up to 60 cm of fresh snow is anticipated. In the remaining ranges, less than 30 cm expected. Esp. in eastern regions, the snowfall forecast is still quite uncertain, it could turn out to be much more. Winds in the Northern Alps will be westerly, brisk, later slackening off. In southern and eastern regions, the southerly winds will intensify. At 2000 m in western regions: -6 degrees, in eastern regions 2 degrees milder.
During Friday night the snowfall will continue esp. in the eastern ranges, then taper off on Saturday morning, sunshine is then expected. The snowdrift problem will persist, avalanche danger will decrease only slowly.
