Moderate danger at high altitudes
At higher altitudes, moderate danger prevails. Avalanche prone locations in the form of older and small-fresh snowdrift accumulations are found on N/E/S facing slopes, in ridgeline terrain, gullies and bowls. By mostly large additional loading, a slab avalanche could be triggered.
Through strong wind impact, snowdrift accumlulations have been generated. These are prone to triggering where they were deposited on top of hoar. These places can occur both between individual layers and in transitions to the old snowpack. The old snowpack itself is weakened by faceted crystals surrounding melt-freeze crusts at high altitudes.
Friday will be brilliantly sunny in Styria. In the southern and eastern massifs it will be milder than in the northwest, temperatures at 1500 m will lie between +3 and +6 degrees at 1500 m, and at 2000 m between +1 and +4 degrees. Strong to stormy NW wind will be blowing.
Very pleasant weather conditions on Saturday. Brilliantly sunny skies, and NW winds will slacken off significantly. Temperatures at 2000 m: +1 to +4 degrees. Avalanche danger will gradually decrease.
