Keep an eye on local weather developments.
Pay attention to the push notifications on the MeteoSwiss app external link.
Pay attention to storm warnings on lakes.
Secure construction sites and boat moorings.
Secure any freestanding objects outside the house, on the balcony or in the garden, or move them to a sheltered spot (plant pots, garden furniture, etc.).

Park your car in a garage if possible.
Check that antennae, solar panels etc. are properly secured.
What to do during strong winds
Storms can sweep through the land with very high wind speeds and strong gusts. They can carry objects along with them, rip off roof tiles, topple trees and create large waves on lakes. You should therefore avoid being outdoors in strong winds if possible.
Recommended action during strong winds:
Keep an eye on local weather developments.
Pay attention to the push notifications on the MeteoSwiss app external link.
Pay attention to storm warnings on lakes.
Avoid activities on water and stay away from lake shore areas.
Stay away from forests and forest edges, exposed trees and groups of trees.
Do not drive along forest roads or tree-lined avenues.
Keep off exposed places such as rooftop areas and rock ledges.
Watch out for falling objects (roof tiles, branches, electric cables, etc.).
Do not repair damage to buildings and infrastructure (e.g. fallen tiles) during the storm, but wait until it has passed.
Always follow the official advice.
What to do after strong winds
When the storm and winds have died down, the immediate danger has passed but a storm can often leave significant structural damage in its wake. Fallen trees and broken electricity pylons or poles can disrupt road and rail traffic for several days afterwards. You should therefore continue to take extra care on the roads and outdoors. This is the time to repair any damage to the house and garden, and to clear away any debris. It is also advisable to have your house or building checked for damage after a very severe storm.
Recommended action after strong winds:
Keep an eye on local weather developments.
Check your house, apartment, balcony and garden for storm damage.
Report any damage immediately to your buildings insurance company and arrange repair work.
Check the condition of trees around the house and in the garden, and have any exposed branches trimmed.
Check the safety of construction sites.
