Rio Grande do Sul faces severe storms and flooding risks

Severe storms, including heavy hail and intense winds, have impacted Rio Grande do Sul, affecting approximately 9,517 people and damaging at least 2,269 residences. The municipality of Santiago was among the hardest hit, with 5,000 people affected and roughly 1,000 homes damaged. In Alegrete, 2,011 people were impacted and 700 houses were damaged.

The Civil Defense has issued alerts for continued severe weather, including potential wind gusts exceeding 90 km/h and significant rainfall. In certain regions, such as the Campanha and Central areas, cumulative rainfall could exceed 270 mm through Tuesday. There is an increased risk of flooding, flash floods, and rising river levels in several monitored rivers, including the Quaraí, Ibirapuitã, and Santa Maria.

Meteorological models suggest the instability may persist due to a combination of a warm front, low-pressure areas, and an approaching extratropical cyclone. Residents are advised to monitor official updates and avoid high-risk areas during active storms.
