Brazil Extends Severe-Weather Alerts as Multi-Day Rains Threaten Large Swaths of the Country

Authorities link the ongoing threat to a frontal system, low pressure and a strengthened Amazon moisture corridor that is sustaining dangerous downpours into early week.

Overview

  • INMET warnings remain active with forecasts of 30–60 mm of rain per hour or 50–100 mm per day and wind gusts of 60–100 km/h across parts of Santa Catarina, Paraná, São Paulo, Minas Gerais, Rio de Janeiro and northeastern Rio Grande do Sul.
  • São Paulo renewed storm alerts, kept the capital under flood attention after an extreme cellphone warning, and scheduled a Civil Defense Crisis Cabinet for Sunday and Monday to coordinate response.
  • The state classified Vale do Paraíba, Serra da Mantiqueira and the North Coast as very high risk, with potential for lightning, strong gusts and isolated hail as instability persists.
  • Additional alerts were issued in other regions, including a mix of orange and yellow advisories in Rio Grande do Sul and yellow notices for heavy rain in Paraíba and Bahia valid into Monday morning.
  • Emergency guidance urges residents to avoid flooded areas and trees, disconnect electronics and use 199 (Civil Defense) or 193 (Fire Department), following a recent São Paulo storm that left one person dead and another missing.
