    Common questions & known issues

    Flood warnings are issued for flooding from rivers and the sea and, for a limited number of locations, for groundwater flooding. There are three flood warning codes and a notification when warnings are removed. These are:

    • 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    • Warning no longer in force: Flood warnings and flood alerts that have been removed in the last 24 hours

    Prior to 2010 flood alert messages were named Flood Watch messages.

    Target Areas represent geographic areas of land.

    Update Flood Alert, Update Flood Warning and Update Severe Flood Warning messages are used to update customers on ongoing flood events.

    Registration to receive messages from Flood Alert Target Areas is optional and is chosen by the customer when registering.

      I would like to include a widget on our website which shows live flood alerts for the local area. We have this for Greater London already, but would be great if we could include at a more local level - to cover the River Pinn/Ruislip. Is this possible?

      Hi Matt,

      The Flood Warning Widgets don't go to that level of detail, but you can pull back warning information for specific areas from our Flood Monitoring API. See https://environment.data.gov.uk/flood-monitoring/doc/reference#flood-warnings
