- Some disruption to road, rail, water and air traffic;
- Possible shutdown of ski lifts and cable cars.
Behaviour:
- Keep an eye on local weather developments
- Stay away from forests

- Top wind speeds in higher-altitude areas (>1800 m above sea level): 130-160 km/h
Danger level 4 (High danger)
Effects:
- Falling trees;
- Damage to individual buildings and roofs;
- Disruption or restriction of road, rail, water and air traffic;

- Electricity grid outages and/or failure of telephone networks
Behaviour:
- Keep an eye on local weather developments
- Stay away from forests
- Secure any free-standing objects
- Always follow the official advice
Description of measurement and prognostic values:
- Top wind speeds in low to medium-altitude areas (incl. Foehn winds): 110-140 km/h
- Top wind speeds in higher-altitude areas (>1800 m above sea level): 160-200 km/h
Danger level 5 (Very high danger)
Effects:
- Falling trees or entire groups of trees or sections of forest as well as electricity pylons and poles;
- Severe damage to buildings;
- Road, rail, water and air traffic disrupted or at a standstill;
- Toppling of larger (empty) vehicles;
- Securely anchored objects with a larger surface area, such as tents and scaffolding, as well as moveable objects such as garden furniture etc. can be blown over;
- High waves on lakes, which wash over the banks or shores
- Electricity grid outages and/or failure of telephone networks for long periods of time and over widespread areas
Behaviour:
- Keep an eye on local weather developments
- Stay away from forests
- Secure any free-standing objects
- Always follow the official advice
Description of measurement and prognostic values:
- Top wind speeds in low to medium-altitude areas: > 140 km/h
