The Turin metropolitan area in northwestern Italy, located between the Alps and hilly terrain, faces growing challenges from intense convective weather events, such as heavy rainfall and hailstorms. These events strain the urban drainage network, increasing flood risks and infrastructure damage. This study examines the impact of such phenomena on Turin's drainage system using data from rain gauges, weather radar, and nowcasting simulations. Radar and nowcasting models were calibrated with a dense rain gauge network to simulate drainage system performance under different storm scenarios. Results highlight the weak points of the existing drainage infrastructure in handling extreme convective events, resulting in localized flooding and potential damage. Integrating high-resolution radar and nowcasting data improved predictions and identified vulnerabilities. The study underscores the importance of incorporating nature-based solutions (NBS) into urban planning as a means of enhancing resilience. These findings support the development of a climate adaptation plan to enhance Turin’s drainage network resilience. The study concludes that combining advanced meteorological monitoring, predictive modeling and sustainable infrastructure, is vital to address the growing frequency and intensity of extreme weather events driven by climate change.
