This paper presents an automated system that analyzes the impact of climate change on extreme weather events in near-real-time using storyline simulations based on a coupled climate model. The system is applied to storm Boris, which caused record-breaking rainfall in Central and Eastern Europe in September 2024. The results suggest that human-induced warming increased rainfall from storm Boris by about 9% and enlarged the area affected by extreme rainfall by 18%. The system's results are publicly available online, showcasing the potential for near-real-time storylines in climate change communication.
