Avalanche danger today in Switzerland
This page shows today's avalanche danger level for every Swiss warning region from the SLF avalanche bulletin: the European avalanche danger level (1 Low to 5 Very high), the main avalanche problems and when each bulletin is valid. Times are Central European time.
Follow the official bulletin and local guidance. This is a summary of the official avalanche bulletin, not a forecast of its own and not advice on where to go. Read the full bulletin for your area before going into avalanche terrain.
The SLF bulletin could not be read just now. See the official avalanche bulletin directly.

The European avalanche danger scale
| Level | What it means |
|---|---|
| Low (level 1 of 5) | The snowpack is generally well bonded and stable. Triggering is generally possible only with a large additional load, on isolated extremely steep slopes. Only small natural avalanches are possible. |
| Moderate (level 2 of 5) | The snowpack is only moderately well bonded on some steep slopes. Triggering is possible mainly with a large additional load, on the steep slopes the bulletin names. Very large natural avalanches are not expected. |
| Considerable (level 3 of 5) | The snowpack is only moderately to weakly bonded on many steep slopes. Triggering is possible even by a single skier or walker, on the steep slopes the bulletin names. Some large, and in places very large, natural avalanches are possible. |
| High (level 4 of 5) | The snowpack is weakly bonded on most steep slopes. Triggering is likely even by a single person, on many steep slopes. Many large, and often very large, natural avalanches are likely. |
| Very high (level 5 of 5) | The snowpack is generally weakly bonded and largely unstable. Triggering is likely almost everywhere. Numerous very large, and often extremely large, natural avalanches are expected, also in moderately steep terrain. |
All five avalanche problems and the scale are explained on the Alpine avalanche danger page.
Questions
What is the avalanche danger in Switzerland today?
No daily avalanche bulletin from WSL Institute for Snow and Avalanche Research SLF is in force for Switzerland right now. The 2026-27 daily bulletins have not started yet. SLF usually starts its daily bulletin in late November or early December and runs it until late April or early May. Before the daily bulletin starts it publishes bulletins only after significant snowfall.
Who issues the avalanche bulletin for Switzerland?
WSL Institute for Snow and Avalanche Research SLF issues it; the official bulletin is at https://www.slf.ch/en/avalanche-bulletin-and-snow-situation/.
What does avalanche danger level 3 (considerable) mean?
The snowpack is only moderately to weakly bonded on many steep slopes. Triggering is possible even by a single skier or walker, on the steep slopes the bulletin names. Some large, and in places very large, natural avalanches are possible. Many fatal avalanche accidents happen at levels 2 and 3, because people are out in steep terrain while the danger looks moderate.
Can I use this page to decide whether to go off-piste or ski touring?
No. This page summarises the official bulletins so you can see the level at a glance; it is not a forecast of its own and leaves out the detail that matters on the slope. Read the full official bulletin for your area and follow local guidance, closures and the advice of mountain professionals.
