Flood Alert Areas
Flood Alert Areas are geographical areas where it is possible for flooding to occur from rivers or the sea. A single Flood Alert Area may cover the floodplain within the Flood Warning Service Limit of multiple catchments of similar characteristics containing a number of Flood Warning Areas. A Flood Alert Area may also match that of a corresponding Flood Warning Area and warn for the possibility of flooding in that area. In some coastal locations a Flood Alert may be issued for spray or overtopping and be defined by a stretch of coastline. Practical and administrative factors may also influence the exact extent of a Flood Alert Area.

This dataset was formerly known as Flood Watch Areas and is now referred to as Flood Alert Areas.
- Additional Information
-
Further information on our flood warning codes is available on the NRW website. Live flood warnings in force are shown on the NRW website in both tabular and map based formats. The live information is updated every 15 minutes. It is also available on our Flood Alerts Wales mobile app. Customers can also obtain recorded messages on the current Alerts and Warnings in force and information on the latest flooding situation for the Flood Alert or Flood Warning Area by telephoning Floodline on 0345 9881188 and using the menu options, or by entering a QuickDial code for the respective Alert or Warning Area.
