Where this comes from. Warnings in force are the Environment Agency’s own, which we check every 15 minutes. They cover England only: for Wales see Natural Resources Wales, for Scotland SEPA Floodline, and for Northern Ireland nidirect.
The history is the Environment Agency’s record of every warning raised since 2006, which it publishes each quarter, joined to the warnings we have recorded live since. Each count is one warning or alert raised for one area; a warning that was later updated counts once. When a warning is removed that is not counted as a new warning. An area with no warnings on record can still flood.
