In recent years, the combined effects of rapid urbanization and climate change have led to frequent floods in urban areas. Rainstorm flood risk warning systems play a crucial role prevention mitigation. However, there has been limited research China on nationwide based rainfall predictions. This study constructs two-level early system (EWS) at national levels using two-dimensional hydrological–hydrodynamic model considering infiltration drainage standards. A methodology for rainstorm warnings is proposed, leveraging short-term high-resolution forecast data provide 231 cities central eastern China. Taking Beijing as an example, refined technique targeting city, district, street scales developed. We validated with monitoring from “7.31” event 2023 Beijing, demonstrating its applicability. It expected that findings this will serve valuable reference
