What the three levels mean
Flood alert
Flooding is possible. Be prepared. Keep an eye on local river levels and forecasts, and get ready to move valuables and put flood protection in place.
Flood warning
Flooding is expected. Immediate action required. Move family, pets and valuables to safety, turn off gas, electricity and water if it is safe to, and put flood protection in place.
Severe flood warning
Severe flooding. Danger to life. Stay in a safe place with a means of escape, and follow the advice of the emergency services. Call 999 if you are in immediate danger.
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.
