Our flood warning service
Our warning service covers around 60% of the properties at risk of flooding from main rivers or the sea in Wales, and we are continually working to extend this service.
You may also be at risk of flooding from other sources which we don’t warn for:
- surface water
- small watercourses
These types of flooding can occur very quickly and are often very localised, meaning there isn’t time to issue advance warning messages.

Move to a safe place
- Move to an upstairs room with a window. You can use this as an escape route if the emergency services tell you to evacuate.
- Find a safe place if you don't have an upstairs. You might have to leave your home if it is safe to do so.
- Contact your local authority to help you with emergency accommodation.

We do not supply sandbags. Find out how to prepare for a flood and choose the right products to protect your property.
If you need sandbags, contact your local authority. They may have some available during a flood. If they do not supply sandbags, you can buy your own from DIY stores and builder’s merchants.
What to do if you are evacuated
Listen to advice from the emergency services and evacuate when told to do so. You will need to tell them if you are self-isolating due to COVID-19.
You will be taken to an evacuation centre run by your local authority. Free food and bedding is provided but you will need spare clothing, essential medication and baby care items if you have an infant.
Most evacuation centres will let you bring your pets. You should take pet food and remember to put cats and small animals in a pet carrier or secure box.
