Cyclone Departs Brazil as Forecasts Flag Cooldown and Central Storm Risk

Overview

• The weekend extratropical cyclone has moved offshore, leaving the South and Southeast more stable under high pressure and polar air after at least six deaths were reported in Paraná.
• Inmet warns of a brief temperature decline of up to about 5°C across parts of Santa Catarina, Paraná, the Southeast and southern Bahia, with forecast highs near 25–27°C in major capitals.
• A separate Inmet storm alert covers a narrow central belt from northern Minas to southern Bahia, including the Federal District and eastern Goiás, with potential winds up to 100 km/h and rainfall near 100 mm.
• São Paulo started Monday at 10°C and southern capitals are set for cool mornings with afternoon sun, including Curitiba at 12°C/23°C and Porto Alegre at 11°C/25°C.
• Meteorologists say a South Atlantic Convergence Zone could form midweek, which would likely return moisture and rain to parts of the Southeast if it materializes.
