Level 1, low

Wind slabs, old snow

The mostly small wind slabs of the last two days are in some cases prone to triggering. They are to be found in particular in gullies and bowls and at elevated altitudes. Avalanches can additionally in very isolated cases be released in the old snowpack also. These avalanche prone locations are rare. Mostly avalanches are small.
Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.

Level 1, low

No distinct avalanche problem

Individual avalanche prone locations are to be found in extremely steep terrain. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

Edition: 18.1.2022, 17:00 / Next update: 19.1.2022, 18:00
Snowpack
Fresh snow drift accumulations have formed in particular at elevated altitudes, but also generally in gullies and bowls. They are prone to triggering, in particular on west, north and east facing slopes, but as a rule are mostly small.
Underneath the wind slabs, the bonding of the snowpack is favourable over a wide area on the northern flank of the Alps and in western Lower Valais. Stability tests (rutschblock and ECT) have triggered fractures in a weak layer lying either on top of or underneath the rain crust that formed at the end of December, in particular upon application of a medium to large additional load. From central Valais through northern Ticino to Grisons, weak layers exist deeper in the snowpack. Individual stability tests have continued to trigger fractures in these layers. For some time now, however, hardly any avalanche releases have been reported in this deep old snow.
Observed weather on Tuesday, 18.01.2022
During Monday night the cloud in the northeast dispersed and the skies became clear, as they were already in the other regions. During the day the weather was sunny.
Fresh snow
-
Temperature
At midday at 2000 m: between +5 °C in the west and +1 °C in the east
Wind
  • During Monday night on the northern Alpine ridge and in Upper Valais, Ticino and Grisons, strong, but storm force in isolated cases, veering from northerly to northeasterly
  • During the day, light to moderate from the east, and in the Jura a moderate to strong bise wind
Weather forecast through Wednesday, 19.01.2022
After a clear night, Wednesday will be sunny. In the evening, cloud will build up from the west.
Fresh snow
-
Temperature
At midday at 2000 m: about 0 °C in the north and -2 °C in the south
Wind
Predominantly light, in the north as the day progresses, moderate southwesterly
Outlook through Friday, 21.01.2022
It will be cold and the wind will be strong to storm force from the north. A little snow will fall in the north, even at low altitudes. The wind will transport fresh snow and loosely bonded old snow. The avalanche danger will increase rapidly on Thursday and is not expected to change significantly on Friday. The main danger is posed by fresh snow drift accumulations, so that no overly large avalanches are to be expected.
 

Your observations can improve the quality of the avalanche bulletin. We are very grateful for any reports and photos received.

Please report your observations of avalanches or alarm signs, or your estimation of the avalanche danger, or simply send us a picture illustrating the current situation. Your report from the field will be considered along with all the other information when we assess the avalanche danger. It is impossible, however, to reflect the exact content of each individual report in the avalanche bulletin.

The best way to file a report is by completing the interactive form on this page. If your report is to be used in the 5 pm avalanche bulletin, it should be submitted before 2:30 pm if possible. Reports received later will normally be given consideration in the next assessment.

No avalanche bulletin is published currently. Nevertheless, you should still stay up to date with the avalanche situation in the mountains, especially if there is fresh snow.

However, the SLF will, by way of exception, also issue avalanche bulletins in the summer in case of heavy snowfall. There are different ways you can be notified when these bulletins based on the snow situation are published:

  • by push alert on SLF's free White Risk mobile app: appearing in four languages (English, German, French and Italian), this can be downloaded from iTunes App Store (for iPhones) or Google Play Store (for Android);
  • via an RSS feed which informs you whenever an avalanche bulletin is published.

Depending on the snow and avalanche situation, the regular publication of avalanche bulletins recommences in November/December.
