Severe windstorms and floods hit southeastern Brazil, prompting red alerts and evacuations
A series of intense windstorms and heavy rains swept through southeastern Brazil on July 29‑30, 2026. In São Paulo state, a man was killed when a falling tree struck him in Santos, and three additional deaths were recorded in the region, including a drowning near Ilhabela. Strong gusts—some exceeding 100 km/h—disrupted metro service in Rio de Janeiro, forced flight diversions at Galeão Airport, and prompted a state‑wide crisis cabinet in São Paulo.
In Rio Grande do Sul, a red alert covering 531 municipalities warned of rain accumulations over 100 mm in 24 hours and wind speeds above 100 km/h. A tornado struck the north‑western part of the state, destroying homes and trees but causing no fatalities. The governor activated emergency plans for all 497 municipalities. In Três Coroas, about 100 residents were evacuated to a municipal gym after the Rio Paranhana rose to 4.5 m following 68 mm of rain.
Paraná experienced widespread power outages, leaving roughly 108,000 customers without electricity as strong winds toppled trees and hindered airport operations at Afonso Pena. Defense Civil agencies issued red‑alert warnings for wind gusts up to 90 km/h in São Paulo and urged residents to stay indoors. President Luiz Inácio Lula declared that Brazil is prepared for potential El Niño impacts, highlighting federal resources allocated for disaster prevention.
