Danger level 1 (No or minor danger)
Danger level 2 (Moderate danger)
Danger level 3 (Considerable danger)
Danger level 4 (High danger)
Danger level 5 (Very high danger)
No danger level
Danger level 1 (No or minor danger)

Explanation of the danger level 1:

  • Avalanches: no danger
  • Earthquakes: may be perceptible
  • Floods: transport disruption and damage are not normally to be expected.
  • Forest fires: small fires cannot be entirely ruled out
  • Meteorological phenomena: no (particular) danger, no warnings in place
Danger level 2 (Moderate danger)

Explanation of the danger level 2:

  • Avalanches: very little danger
  • Earthquakes: felt across a wide area, no likelihood of damage to buildings
  • Floods: rivers are unlikely to burst their banks and floods are unlikely but not impossible
  • Forest fires: local fires can start spontaneously
  • Meteorological phenomena  that are normal for the respective season
Danger level 3 (Considerable danger)

Explanation of the danger level 3:

  • Avalanches: exposed objects (mostly sections of transportation routes) can be endangered
  • Earthquakes: felt across a wide area, likelihood of minor damage to buildings
  • Floods: rivers may burst their banks locally in exposed places and flooding may occur.
  • Forest fires: surface fires are likely
  • Meteorological phenomena of an intensity slightly superior to the normal
Danger level 4 (High danger)

Explanation of the danger level 4:

  • Avalanches: exposed objects (mostly sections of transportation routes, but in isolated cases also buildings) can be endangered
  • Earthquakes: felt strongly, likelihood of damage to buildings
  • Floods: rivers may increasingly burst their banks and flooding may occur
  • Forest fires: surface fires are very likely
  • Meteorological phenomena of unusual intensity
Danger level 5 (Very high danger)

Explanation of the danger level 5:

  • Avalanches: transportation routes and settlements can be seriously endangered
  • Earthquakes: felt strongly, high likelihood of widespread and severe damage to buildings
  • Floods: rivers may burst their banks and flooding may occur in many places
  • Forest fires: fires can start at any time
  • Meteorological phenomena of very high intensity

Obey in any event the orders issued by your local authorities and be prepared for exceptional measures.

  • Avalanches: 

    Avalanches: 

    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.
    The criteria governing the publication of an avalanche bulletin in the summer and autumn are described in the Interpretation Guide.
    Depending on the snow and avalanche situation, the regular publication of avalanche bulletin recommences in November/December.
