Natural Resources Wales: Wales Flood Areas with Current Severity

This layer is experimental, be sure to check the data currency against the Natural Resources Wales website. This Feature Layer is generated automatically by a Python notebook pulling data from the Natural Resources Wales Flood Monitoring API every 60 mins. A warning may be at one of four possible severity levels: Severe flood warning (severe flooding, danger to life) Flood warning (flooding expected, immediate action required) Flood alert (flooding is possible, be prepared) Warning no longer in force This layer is currently publicly accessible to fulfil British Red Cross' operational requirements. If you are viewing this layer from another organisation, it is strongly recommended that you access data directly through the Natural Resources Wales Flood Monitoring API.
