Inmet Issues Red Alerts for Severe Storms in Southern Brazil

Overview

• Inmet warned Nov. 4–5 of hot, humid conditions across the Sul, Sudeste, Centro-Oeste and western North that favor afternoon and evening convective storms.
• The agency placed a red-level danger alert over much of the Sul, including Santa Catarina, parts of Paraná and the north and northwest of Rio Grande do Sul, where intense downpours and severe storms are likely.
• Orange and yellow warnings cover parts of the Centro-Oeste and the São Paulo–Paraná border with the south of Mato Grosso do Sul singled out for higher risk of thunderstorms.
• Local G1 forecasts drawn from Climatempo show a common pattern of morning sun or clouds followed by afternoon and evening showers in many cities while Belo Horizonte has a yellow alert and its Defesa Civil is advising precautions and providing alert channels including SMS alerts and a 24‑hour hotline.
• The Northeast coast is expected to stay mostly sunny and hot while meteorologists stress that warnings are updated daily and that short‑term monitoring is needed for hazards such as hail, strong gusts, floods and landslides during the seasonal rainy period through March 2027.
