Extratropical Cyclone Pounds Southern and Southeastern Brazil, Cutting Power and Snarling Transport

Overview

• Authorities confirmed three deaths in Palhoça, Santa Catarina, after flooding swept away a car, as the system delivered heavy rain and a reported tornado in Flores da Cunha (RS).
• In Greater São Paulo, power outages climbed to nearly two million customers at peak, with gusts reaching 98.1 km/h in the Lapa area and 514 tree-fall calls leaving four people lightly injured.
• Service disruptions spread across the capital: parks were closed, Hospital São Paulo reported hours without electricity earlier in the day, Sabesp flagged water supply impacts tied to the blackout, and CPTM’s Line 10 operated with delays.
• Flight operations were curtailed as Aena reported 45 arrivals and 48 departures canceled at Congonhas and 22 arrivals and 15 departures canceled at Guarulhos, with additional diversions to other airports.
• Strong winds also hit Paraná—peaking at 131.8 km/h at the Marumbi station—destroking a school roof, toppling trees and prompting event cancellations, while Petrópolis, Sorocaba and Alto Tietê logged blocked roads, facility closures and localized rescues.
