New snow, Wet avalanches
Avalanche prone locations
Danger level "considerable" (3) in all aspects and altitudes.
Danger description
The avalanche prone locations for dry avalanches are to be found in all aspects above approximately 3000 m. An increasing number of natural dry avalanches are possible as a consequence of the snowfall. They can in some cases release the saturated snowpack and reach large size.
The avalanche prone locations for wet avalanches are to be found below approximately 3000 m. As a consequence of the rain at any time medium-sized and, in isolated cases, large wet avalanches are to be expected.
Experience and restraint are required.
Remarks
This is the final hazard map for the winter 2022/23. In the summer and autumn, avalanche bulletins are published only in the event of heavy snowfall. Even if the SLF does not publish an avalanche bulletin, due consideration is to be given to the avalanche situation especially if snow has fallen recently.
Wet avalanches
Avalanche prone locations
Danger level "considerable" (3) in all aspects and altitudes.
Danger description
The avalanche prone locations for wet avalanches are to be found below approximately 3000 m. Outgoing longwave radiation during the night will be severely restricted. In particular in starting zones where no previous releases have taken place wet avalanches are to be expected. These can in some cases release the entire snowpack and reach large size in particular on north facing slopes.
Snow drift
Individual avalanche prone locations for dry avalanches are to be found in particular on west, north and east facing slopes above approximately 3000 m. The fresh and somewhat older wind slabs are in some cases prone to triggering. They are to be evaluated with care and prudence in steep terrain. Avalanches can reach medium size.
Meticulous route selection is advisable.

Dry avalanches: no distinct avalanche problem
Avalanche prone locations
Danger level "moderate" (2-) in west to north to east facing aspects above 3000m. Other slopes about one danger level less.
Danger description
Avalanches can in some cases be released in near-surface layers and reach medium size. 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.
Wet avalanches as day progresses
As a consequence of warming during the day and solar radiation wet snow slides and avalanches are possible as the day progresses. This applies below approximately 3000 m. Avalanches can in isolated cases release the entire snowpack and reach large size in particular on north facing slopes. Backcountry tours and ascents to alpine cabins should be concluded timely.

Even if the SLF does not publish an avalanche bulletin, due consideration is to be given to the avalanche situation especially if snow has fallen recently.
Wet avalanches
The snowpack is wet. Individual wet snow slides are possible. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

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.
Other reporting options:
- White Risk App
- E-mail to bulletin(at)slf.ch
- Freephone number 0800 800 187

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.
