Persistent weak layers
- Above 1,700 m
Persistent weak layers in high altitudes, increasing wet snow problem in medium altitudes.
The avalanche danger is moderate above 1.800 m. the weakend old snow cover underneath the fresh snowdrift deposits are the main problem. Danger Spots are located in northwest- and eastern expositions and are increasing in higher altitudes. Especially in entries and in peripheral areas ti extremly steep gullies and bowls slab avalanches can be triggered. THese can reach medium sizes. In medium altitudes spontaneous wet slab avalanches especially in extremly steep eastern slopes are possible.h
The snowcover is in general unusually thin considering the season. it is already in high altitudes moist and partially wet to the ground. Tuesday fresh snowdrif deposits are accumulating in Northern and eastern expositions on top of a moist and -due to faceted snow crystals weakend - old snow cover.
Tuesday night snowfalls in upper Stytria down to 1.000 m. Wednesday morning is predominately dry and the clouds are clearing up. Only the summits of Niedere Tauernand Gurk- and Seetaler Alps can be foggy. Moderate westerly to southwesterly winds. Temperatures are around -3 degress on 2.000 m at noon.
Thursday is predominately sunny and temperatures are around 5 degrees higher than Wednesday. Due to that the setteling of the snow cover is advanced.
