Grounded in data. Clear about the limits.

Levels, rainfall and flood warnings come from the Environment Agency real-time data API (Beta) and are refreshed every 15 minutes. We add our own reading of that data: trend, comparison against each station's own history, and early warning signals derived from upstream rainfall. Those predictive signals are in beta and are being validated through this flood season.

Flood Monitor is supplementary to official Environment Agency flood warnings and is not a safety-critical service. In an emergency, follow the advice of the Environment Agency and the emergency services.
