In this article, we present the extreme precipitation event that occurred in the Guaíba Hydrographic Region (RHG) in the fall of 2024, from the perspective of geographic climatology. We initially discuss the concepts of climate extremes and the proposed analysis of the succession of three precipitation events in sequence. For this analysis, daily data from INMET and CEMADEN meteorological stations were organized. The three events were: the first, with 500mm, on average; followed by another with 200mm; and the last one of 100mm. The distribution of precipitation indicates an orographic effect and triggered mass movements on the slopes and extraordinary floods, especially in the Metropolitan Region of Porto Alegre, where the flood protection system collapsed, due to lack of maintenance.
