Isolated danger zones from snowdrifts at high altitude
In the Mürztal Alps and eastern rimline ranges avalanche danger is low. On Wednesday a small amount of fresh snow was registered. Small drifts were generated: prone to triggering in gullies, bowls and behind protruberances. The snowpack surface is hard in exposed terrain.
Some fresh snow was deposited atop a wind-impacted old snowpack surface at high altitudes. In shady high-altitude terrain the fresh snow and drifts were deposited atop a hardened old snowpack. At low altitudes, bonding to the often shallow snowpack is better. Stormy winds are having their effect on the hard surface.
In the Northern Alps and along the Niedere Tauern, clouds will accumulate, fog will move in, minor snowfall is possible on Epiphany. Starting at midday, skies will brighten somewhat, the highest peaks may become free. Much more pleasant conditions prevail on the southern flank of the Alps, the summits are free from the start and clouds will disperse and make room for the sun in the morning. An icy NW wind will be blowing briskly. At 2000 m: -10 degrees at midday; at 1500 m: -6 degrees. Winds will make it feel colder. On Friday, mostly sunny and cold, good visibility. The SW winds wil be light-to-moderate.
No change in avalanche danger.
