INMET Alerts Through Saturday: South Risks Hail, North Faces Downpours, Southeast Heats Up

Overview

• Inmet’s orange and yellow warnings remain in effect through Saturday morning across multiple states, including Tocantins, with projections of 30–60 mm/h or 50–100 mm/day of rain and wind gusts up to 100 km/h.
• Southern Brazil, especially Rio Grande do Sul and Santa Catarina and parts of Paraná, has elevated risk of severe storms with lightning, strong gusts and possible hail under the influence of a coastal frontal system.
• The North remains the most impacted region, with widespread instability over Amazonas, Pará, Amapá, Rondônia and nearby areas bringing persistent heavy rain and the threat of flooding, fallen trees and power outages.
• In the Southeast, storms are scattered and short‑lived while inland pockets face health advisories for dry heat, including an INMET low‑humidity alert for Campinas (20%–30% RH) and forecast highs above 30°C in the Vale do Paraíba and surrounding cities.
• Authorities urge residents to follow Civil Defense guidance and standard safety steps during storms, and meteorologists note a system could become more organized between Sunday and Monday, potentially shifting risk zones.
