The Environment Agency flood-monitoring API provides developers with access to near real time information covering: flood warnings and flood alerts flood areas which to which warnings or alerts apply measurements of water levels and flows information on the monitoring stations providing those measurements Water levels and flows are regularly monitored, usually every 15 minutes. However, data is transferred back to the Environment Agency at various frequencies, usually depending on the site and level of flood risk. Transfer of data is typically once or twice per day, but usually increases during times of heightened flood risk.
