Front Brings Rain and Strong Winds to Southeast as Polar Air Freezes the South

Overview

• The city of Rio de Janeiro was warned Wednesday by the Centro de Operações e Resiliência about strong coastal gusts and increased cloud cover that could bring moderate rain and disrupt traffic.
• A cold front continues to drive rain along the coast of Paraná, São Paulo and Rio de Janeiro with periods of moderate showers even as the system gradually loses strength.
• A mass of polar air following the front has sharply dropped temperatures in the south and created conditions for frost in highland areas of Rio Grande do Sul and Santa Catarina with lows near 0°C.
• Weather service Climatempo says intense storms are likely to return to Rio Grande do Sul from Friday with the heaviest rain in the northwest and border areas and a new surge of cold arriving on Saturday.
• Cemaden has active risk alerts for heavy rain in parts of the North while inland regions of the Centre-West show low humidity between 21% and 30%, raising concerns for fire risk and agricultural stress.
