Rio Grande do Sul under heavy rainstorm alerts, widespread damage
The National Institute of Meteorology (Inmet) first issued a yellow storm alert for Rio Grande do Sul on 27 July, warning of rain of 20‑30 mm per hour, winds of 40‑60 km/h and hail. The agency subsequently raised a red (great‑danger) alert covering 531 municipalities in the state, forecasting precipitation exceeding 60 mm per hour or 100 mm per day, with some forecasts showing up to 180 mm in 36 hours. Between 27‑28 July a series of severe temporals produced wind gusts of 87.8 km/h in Ibirubá and over 95 km/h in Osório, destroying more than 1 000 houses, toppling trees, and leaving about 62 000 customers without electricity. Over 500 homes were damaged by hail in Santo Antônio das Missões, and 350 homes suffered similar damage in Ernestina. Governor Eduardo Leite stressed that protecting lives is the top priority, and the state’s civil‑defence agencies deployed shelters, issued evacuation advice and monitored river levels, especially the Sinos and Uruguai, which are at risk of overflow. Meteorologists linked three heavy‑rain episodes in the past fifteen days to the strengthening El Niño, noting that saturated soils and high river levels increase the likelihood of floods and landslides. The prolonged excess rain in the South also threatens wheat production, with the National Supply Company (Conab) projecting a wheat harvest of 6 million tonnes—23.5 % lower than the previous year—while drought in the Central‑West endangers the upcoming soybean planting.
