Storm System Disrupts Brazil’s Centre‑South on Election Day

Overview

• A low‑pressure area from Bolivia/Paraguay and a newly forming extratropical cyclone off the southern coast organized a frontal band over the weekend that produced heavy rain, thunderstorms, hail and strong gusts across the centre‑south on Sunday.
• The National Institute of Meteorology issued yellow, orange and red alerts for parts of the South, Southeast and Centre‑West, and São Paulo’s emergency center warned of flooding, fallen trees, landslides and gusts that can exceed 60 km/h.
• Weather already changed election logistics: the Tribunal Regional Eleitoral of Paraná moved a polling station in Barracão, transferring about 3,200 voters to a safer site because of storm impacts.
• Conditions vary sharply across Brazil with the South and much of the Southeast turning cooler and wetter while the North, Northeast and parts of the Centre‑West remain hot with some capitals near 37–40°C.
• Forecasters say the front should continue to lower temperatures into Monday and authorities urge voters and travelers to monitor Inmet and Civil Defense alerts because localized flooding, fallen trees and power outages may still disrupt access to polling places and roads.
