Level 2, moderate

Avalanche prone locations
In all aspects above approximately 1400m.

In all aspects above approximately 1400m.

Danger description

Fresh and older wind slabs represent the main danger. The wind slabs are to be evaluated with care and prudence in particular in very steep terrain.
Moist snow slides and avalanches are possible below approximately 1600 m, in particular on steep south facing slopes. Ski touring and snowshoe hiking call for careful route selection.

Level 3, considerable

Wind slabs

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

Fresh and somewhat older wind slabs can be released by a single winter sport participant in some cases. Caution is to be exercised at their margins in particular. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.

Level 3, considerable

Wind slabs, old snow

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

Wind slabs can especially at their margins be released by people. In some places avalanches can also release deeper layers of the snowpack and reach dangerously large size. In addition individual natural avalanches are possible. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.

Gliding avalanches

Below approximately 2000 m gliding avalanches and moist snow slides are possible.

Level 3, considerable

Old snow, wind slabs

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

Over a wide area various wind slab layers are lying on a weakly bonded old snowpack. Avalanches can be released in the weakly bonded old snow, even by a single winter sport participant. In addition individual natural avalanches are possible. The avalanches can release the entire snowpack and reach a dangerous size. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger.

Level 2, moderate

Wind slabs

Avalanche prone locations
In all aspects above approximately 2000m.

In all aspects above approximately 2000m.

Danger description

Fresh and somewhat older wind slabs are in some cases prone to triggering. Mostly the avalanches are only small but in some cases easily released. Caution is to be exercised in particular on wind-loaded slopes.

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 bulletins are being published at the moment. 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);
  • by mobile text message (SMS): please send an SMS with the message START SLF SOMMER to the phone number 9234 – you can cancel this service at any time by sending an SMS with the message STOP SLF SOMMER; cost: CHF 0.20 per SMS;
  • 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 bulletin recommences in November/December.
