Cold Front to Bring Heavy Weekend Storms and Sharp Cooling to Southern Brazil

Overview

• National and regional services led by Inmet say a new cold front and linked low‑pressure areas will fuel intense charged clouds and temporals across the South, Center‑West and Southeast over the weekend.
• Forecasts point to the strongest rainfall in Paraná and Santa Catarina on Saturday–Sunday with localized flood and landslide risk in low‑lying and slope areas.
• A polar air mass is expected to enter from Sunday (Nov 8), which Inmet and model syntheses show will cause a rapid and marked fall in temperatures, especially across the South and parts of the Southeast.
• Meanwhile the North and Center‑West will stay very hot with daytime highs near 35–39°C and a continued chance of afternoon or evening storms, and parts of the Northeast remain under orange alerts for very low humidity.
• Officials advise residents, emergency services and local governments to monitor updated Inmet and regional forecasts, prepare for flash flooding in vulnerable neighborhoods and protect heat‑sensitive groups as conditions change.
