Brazil (Update)
On 30 September 2026, the Brazil National Center for Monitoring and Early Warning of Natural Disasters (CEMADEN, per its acronym in Portuguese) reported continued heavy rainfall across southern Brazil, with accumulations potentially exceeding 70 mm within 24 hours in parts of Santa Catarina and Paraná. A high hydrological risk was identified in parts of Rio Grande do Sul due to ongoing flooding in the Quaraí, Santa Maria, and Taquari river basins, and in Foz do Iguaçu, Paraná, due to the potential for intense rainfall, flash flooding, and overflowing streams. Moderate hydrological risk was also reported in other areas of Rio Grande do Sul, throughout Santa Catarina, and in parts of Paraná. CEMADEN additionally identified the potential for localized landslides in Santa Catarina and Paraná due to accumulated rainfall and continued precipitation. According to media reports, 68,542 people have been affected across 130 municipalities in Rio Grande do Sul, including 6,396 people displaced and four injured, with more than 8,000 homes damaged. No deaths or missing persons associated with the event have been reported in the state.
