Summary

Flood Warnings are provided by the constant monitoring of stations and forecasting flooding from rivers or the sea:

  • Severe Flood Warning: Severe flooding. Danger to life.
  • Flood Warning: Flooding is expected. Immediate action required.
  • Flood Alert: Flooding is possible. Be prepared.
  • Warning no longer in force: Flood warnings and flood alerts that have been removed in the last 24 hours.

Flood Warnings are available on our website and as a Live Feed. The live feed provides a summary of flood warnings (Alert, Warning and Severe) that are sent externally. The Flood Warnings Live Feed provides current status update of every Flood Warning Area in England and Wales. This is updated on the Flood Warning Information System (FWIS) service every minute although it is presented for external users every 15 minutes via the Data Distribution Hub where the XML can be securely downloaded (sFTP feed).
