Inmet Issues Orange Alerts for Centre‑South Storms as Northeast Swelters

Overview

• Inmet issued orange-level warnings on Monday for municipalities in Paraná, São Paulo and Mato Grosso do Sul that warn of up to 100 millimeters of rain in 24 hours, wind gusts near 100 km/h and possible hail.
• A moisture corridor stretching from the North to the South is producing unstable conditions that favor afternoon and evening convective showers and isolated temporais across the Centre‑South.
• Local authorities have published targeted safety guidance: Rio’s Alerta Rio and Climatempo warned of strong gusts and lightning, Inea listed beaches safe for bathing and advised avoiding seawater for 24 hours after rain, and Codesal in Salvador projected hot, dry air with gusts up to 45 km/h.
• Forecasts show heat holding through midweek in many states with highs into the mid‑ to high‑30s Celsius, and meteorological services say a frontal passage later this week could cool some coastal areas while raising storm risk elsewhere.
• Residents are urged to prepare for localized flooding, fallen trees and power outages by avoiding flooded roads, staying away from riverbanks and keeping emergency numbers at hand because orange alerts signal danger that can affect transport, utilities and public safety.
