The weather this week is expected to be severe, with the possibility of gusts of wind, hail and electrical discharges. The areas with the greatest potential for events are concentrated in the West, Center, Missões, Vales, Serra and Metropolitan Region of Porto Alegre. Forecast of 'strong' El Niño in 2026 rekindles flood alert and tests RS's preparedness In the next 15 days, forecasts point to a period marked by successive episodes of severe weather and voluminous rain, with accumulations that, in some regions, could exceed 200 to 300 millimeters. The current forecast also indicates the continuation of instability between July 31st and August 2nd. According to Civil Defense, there is still divergence between meteorological models regarding the intensity and location of the largest accumulations, but there is a possibility of new episodes of heavy rain. Possibilities of flooding are a concern Civil Defense highlights the possibility of flooding in municipalities located along the Ibirapuitã rivers, in Alegrete; Santa Maria, in Dom Pedrito and Rosário do Sul; Ibicuí, in Manoel Viana; and Quaraí, in the municipality of Quaraí. The greatest risks are concentrated on the Uruguai, Quaraí, Ibirapuitã, Santa Maria, Ibicuí, Jacuí and Sinos rivers. This Sunday (26), the Uruguay, Jacuí and Sinos rivers already had monitoring points above the flood level. The concern is due to the fact that the main rivers in the Guaíba and Uruguay basins are expected to remain at high levels, even above flood levels in some stretches, especially in areas located downstream of the large basins. This Sunday (26), the Uruguay River was above the flood level in the municipalities of São Borja and Itaqui, but no disturbances were recorded. In the basins of the Taquari-Antas, Caí and Jacuí rivers, the tendency is for high levels to remain, with stabilization or even a slow reduction in some points. However, the spread of the flood will continue to impact sections downstream, especially in the regions of General Câmara, Triunfo, Charqueadas, Eldorado do Sul and the Islands of the Metropolitan Region of Porto Alegre, where the risk of flooding in riverside areas remains. Civil Defense issued, on Saturday night (25) and Sunday morning (26), two alerts indicating a very high risk of flooding. The alert applies to both the Uruguai River, in Itaqui, and the Rio dos Sinos, in São Leopoldo. Climatempo predicts rainfall volumes of up to 250mm between Monday (27) and Wednesday (29).
