Field notes
The page describes combining 51 ECMWF forecast runs for a chosen location with recent rainfall measured against a 30-year record. It says an agent checks areas every six hours and drafts email alerts, with a person approving them before they go out. For its historical replay, the project reports advance flags for 29 of 36 past African floods; those results are self-reported on the homepage.
