Postpone any trips out, whether it is on foot or by car.
Leave your children at school or at a daycare centre. They will be safe there.
Either stay or go inside a building. Go upstairs.
Cut off supply networks
If possible, cut off any gas, electricity and heating supply, without putting yourself at risk.
Just a few centimetres of flowing water can be enough to sweep away a car. Do not go out in your car or stay inside it.
Do not go underground
Do not go into a basement or underground car park.
Stay away from waterways
Stay away from waterways, riverbanks and bridges. To avoid lightning, do not take shelter under a tree.
Keep up-to-date with the situation and observe instructions issued by the emergency services and/or the local council.
Look out for others
Look out for vulnerable and isolated people, and communicate via SMS to leave any telephone lines available for the emergency services.
