Hurricane-force gusts, hail and falling trees threaten buildings, power lines and traffic. Heed the warning levels from MeteoSwiss.
Immediate measures
- Secure loose objects
- Close windows and blinds
- Avoid forests and open spaces

Immediate measures
- Clear the cellar, secure the drains
- Avoid underground car parks and underpasses
- Switch off the power in flooded areas
Switzerland lies in a moderately active zone. A strong quake is rare but possible – damage arises mainly from debris.
Immediate measures
- Drop, cover, hold on
- Move away from windows and shelves
- After the quake, check gas and electricity
Avalanches, debris flows and landslides threaten alpine regions and transport routes. Local situation reports and closures are binding.
Immediate measures
- Check the avalanche bulletin (SLF)
- Respect closed routes
- Emergency equipment in the field
Heatwaves strain the circulatory system and infrastructure; drought aggravates water shortages and the risk of forest fires.
Immediate measures
- Drink plenty, avoid the midday heat
- Cool and darken the home early
- Strictly observe fire bans
Drought, heat and wind can set forests ablaze quickly – above all in Valais, Ticino, Graubünden and foehn valleys. Take fire bans and danger levels seriously.
Immediate measures
- At a high danger level, no open fire outdoors
- Strictly observe the cantons' fire and barbecue bans
- Report a fire immediately to the fire brigade on 118
A powerful geomagnetic storm can disrupt power grids, GPS, and radio communications. In extreme cases, a widespread blackout threatens — preparations similar to those for a power outage help.
Immediate measures
- If blackout risk: activate the same preparations as for a power outage
- Have a battery-powered/hand-crank radio ready for information
- Expect inaccuracies in GPS/radio communications
