Cyclone Triggers Storm Warnings Across Southern Brazil

Overview

• A developing extratropical cyclone over the South has prompted Inmet, Simepar and regional services to issue 'perigo potencial' storm alerts for large parts of the Região Sul and sections of the Sudeste and Centro-Oeste.
• Alerts forecast rainfall rates of about 20–30 mm per hour with daily totals up to 50 mm and wind gusts commonly near 40–60 km/h, conditions that authorities warn can cause flash flooding, roof damage and power outages.
• Rain and thunderstorms extended through Monday into Tuesday, and hail was recorded in São João do Triunfo, Paraná, with local officials reporting no major damage as of the latest updates.
• Emergency agencies including Defesa Civil have advised people to follow official bulletins, register for local alert messages, secure loose objects and call emergency numbers (Defesa Civil 199, Corpo de Bombeiros 193) if hazards appear.
• Forecasters say the cyclone-driven instability should ease when a cold, dry air mass arrives from Wednesday, though separate forecasts warn of very heavy accumulated rain in parts of the Amazon over the coming week.
