Cyclone and Frontal Band Keep Centro‑Sul on High Storm Alert

Overview

• Inmet has issued multi‑state warnings for the Centro‑Sul with red and orange alerts over parts of Santa Catarina, Paraná and Rio Grande do Sul and a nationwide advisory for Sunday that forecasts up to 50 mm of rain and winds near 60 km/h.
• São Paulo’s Defesa Civil activated a Gabinete de Crise for the Nov 5–7 period to prepare for temporais that may bring gusts up to 80 km/h, isolated hail, flooding, fallen trees and power outages.
• Paraná remains under high alerts after damaging storms earlier this week, including an F2 tornado recorded in Maringá, and state authorities continue to circulate emergency numbers and safety guidance.
• Meteorologists say the risk lasts because the cyclone is strengthening a frontal band in very hot, humid air, which favors afternoon and evening organized convective cells that can produce heavy downpours, strong gusts and rare tornadoes.
• Local forecasts vary: Santa Catarina is expected to ease as the front moves offshore while São Paulo, Rio de Janeiro and Minas Gerais face renewed instability through the weekend and officials urge residents to follow alerts via SMS and call Defesa Civil (199) or Bombeiros (193) in emergencies.
