In sintesi

Low avalanche danger, but persistent weak layer problems in the northern and eastern exposures!

Problemi valanghivi

  • Persistent weak layers

    • Above treeline

Tendency

The avalanche risk is not expected to increase. In the night to Thursday, some new fallen snow will only fall in the eastern northern Alps, in the west it will remain mostly precipitation-free. During the day there will still be some clouds and fog in windless conditions. Apart from a few snowflakes, no significant new fallen snow is expected.

Avalanche Activity

Low avalanche danger, but persistent weak layer problems in the northern and eastern exposures!

The avalanche risk is low. In the northern and eastern exposures, there is still a persistent weak layer problem at altitudes above the tree line. In addition, fresh pillows of wind drifted snow have formed with the strong south-westerly wind. In steep terrain, these can be triggered in a few places. However, even if the old snowpack is torn through, the avalanches usually remain small. In general, the risk of entrainment, falling and injury outweighs the risk of burial. However, be careful in the area of terrain traps.

Snowpack Structure

There is still significantly less snow than average. A thin, partly bound snowpack covers a very variable and mostly hard old snowpack. There is significantly more snow in shady gullies and bowls than on sunny slopes, some of which are partly bare up to 2000 metres. In the northern and eastern exposures, the snowpack is still weakened by layers with faceted crystals and floating snow (persistent weak layer problem!).

Weather Forecast

In the northern Alps and generally at altitudes above 1500 metres, the night will be cloudless. Clouds will gather from the south on Tuesday. While the peaks of the western Northern Alps will remain fog-free, visibility will deteriorate from Hochschwab to Veitsch. However, there will be no precipitation. The temperature at an altitude of 2000 metres will be between -8 and -1 degrees. The temperature at an altitude of 1500 metres will be between -4 and 2 degrees. Brisk to stormy winds with gusts between 40 and 60 km/h from south to south-west.
