Regionally very high avalanche danger in the Swiss Alps

 

Since Saturday evening there has been heavy and persistent snowfall registered in the mountains. By Sunday evening along the northern sector of the Main Alpine Ridge there was as much as 60 cm of fresh snow registered. The intensive precipitation is expected to persist throughout the night and into the day on Monday. By Monday evening, the following amounts of fresh snow are expected from the eastern part of the Bernese Oberland as far as the Alpstein, in northern Upper Valais and in the Silvretta: an additional 60-100 cm of fresh snow.

In the northeastern regions, a great deal of snowfall has been registered over the last two weeks. There, the snow depths are above-average for this juncture of the season, which is to say, as much as 150-200% of the customary depths of snow have been registered.

The SLF ranks avalanche danger for Monday, 14 January, at the very highest danger level (5, “very high”) for the following regions:

  • On the northern flank of the Alps from the eastern part of the Bernese Oberland as far   as the Glarnerland
  • Silvretta

This danger level prevails only very seldom. Over widespread areas it was assigned in January 2018 the last time and, previously, in the avalanche winter of 1999. Numerous, in some cases large-sized avalanches, are expected. These avalanches can plummet as far down as the valley floors. They can also place transportation routes and property at risk which are seldom endangered. The instructions of the avalanche authorities and local security services must be obeyed without hesitation or delay.

In many further regions of Switzerland, danger level 4 (high) prevails. Also in those regions, extremely critical conditions currently reign. Exposed transportation routes and isolated buildings can be endangered, that is, are at risk.  In all regions which are indicated, we urgently advise against all backcountry snow sports in outlying terrain away from secured and marked ski runs.

As of the end of this period of precipitation, the avalanche situation will incrementally calm, starting on Tuesday. The next avalanche bulletin will be published on Monday, 14 January 2019 at 8:00 am.
