During flooding, the latest information about services and road conditions will be available here:   



Flood warnings

For a list of flood warnings and advice visit the Natural Resources Wales website or call 03000 65 3000.
If you live in an area which suffers from flooding, Natural Resources Wales can warn you if any flood warnings are issued in your area. The service is completely free of charge.



When there is flooding, during severe weather or high tides, the Council will try to supply sandbags to people who ask for them if there is a high risk of imminent flooding of the property. The Council's ability to supply sandbags depends on the workers' availability because of the extent and severity of the floods.
