Persistent weak layers in high altitudes!

Persistent weak layers in high altitudes!

Moderate avalanche danger above 1.900 m, below that: low avalanche danger. Danger spots are located in high shady slopes behind ridgelines and in the beginnig of gullies and bowls as well as steep slopes. Slab avalanches within the old snow can be triggered by small additional load and can reach medium sizes especially in transition areas from thin to thicker snow covers. on sunny slopes increasing danger of small spontaneous wet- or gliding snow avalanches. Avoid areas below glide cracks.

During the night surface hoar will form on sunny slopes with different amounts. It will soften during the course of the day. Summits are blown-off and icy or bare, gullies and bowls are filled with old snowdrift. In shady high altitudes the snow cover is weakened due to layers of faceted snow crystals and sometimes snown in Graupel within the old snowdrift accumulations. Surface hoar has formed especially in basins. In shady slopes the surface is built-up and loose. On smooth surfaces the snow cover can start gliding any time.

The high pressure system comes to its end. Nights are predominantly clear and the morning will still be sunny but during the course of the day clouds form coming from north. The summit of Alpenhauptkamm will be foggy in the afternoon. Light snowfall will start in the evening. Vivid southwesterly winds are cooling off. Temperatures at noon in 2.000 m are 1 degrees but decreasing during the afternoon. Thursday night the temperatures will drop and light snowfall starts. Temperatures in the north and central Alps will drop to 2-digit Minusdegrees on 2.000 m.

New danger spots will form due to new snow, wind and snowdrift.
