 The `eafm` integration offers integration with the [UK Environment Agency Flood Monitoring](https://flood-warning-information.service.gov.uk/) API to provide sensors for nearby water levels. Combined with Home Assistant notifications, you could give yourself a warning if a nearby river was likely to flood your local cycle path or the only road out of your village.

+The UK Environment Agency Flood Monitoring only provides data for England - Northern Ireland, Scotland and Wales have their own flood agencies.

 ## Configuration
 
 Home Assistant offers the flood monitoring integration through **Configuration** -> **Integrations** -> **Environment Agency Flood Gauges**.
