On the afternoon of March 31, 2025, Greater São Paulo was struck by a powerful rainstorm, causing significant disruptions and damage, particularly in the Southeast region and the ABC Paulista area. The deluge led to severe flooding, with images circulating on social media showcasing hailstorms and the Celso Daniel train station in Santo André submerged under water.
The train station, part of the CPTM's Linha 10 (Turquesa), experienced operational challenges due to flooding on the tracks, which resulted in a suspension of train services between the Prefeito Celso Daniel-Santo André and Mauá stations. Reports indicated that the rain was so intense that it caused a house to collapse in Jardim Zaíra, Mauá, although fortunately, there were no injuries.
By 14:47, the Civil Defense of São Paulo had issued a "severe alert" for residents in the affected areas, warning of high risks for flooding and landslides. The alert urged residents to stay in safe locations as the storm intensified. In Santo André, Avenida dos Estados was rendered nearly impassable due to the overflow from the Tamanduateí River, while flooding was also reported in the Guarara stream and the Corumbé River.
