São Paulo Renews Orange Alert for Intense Rains as Crisis Cabinet Mobilizes

Forecast models point to a moisture-laden frontal setup that could consolidate a new South Atlantic Convergence Zone early this week.

Overview

  • State civil defense reissued a statewide warning on January 18, classifying Vale do Paraíba, Serra da Mantiqueira, and Litoral Norte as very high risk.
  • A crisis cabinet is being installed on January 18–19 to reinforce monitoring, interagency coordination, and incident response.
  • Meteorologists attribute the widespread rain to a cold front, a surface low, and an Amazon moisture channel, with heavy accumulations possible.
  • Authorities warn of storms with gusty winds, lightning, and isolated hail, and advise avoiding flooded or tree-lined areas, unplugging electronics, and using 199 (Civil Defense), 193 (Fire Department), and SMS alerts via CEP to 40199.
  • In a separate development, Rio Grande do Sul issued "danger" warnings for very intense rain and 60–100 km/h winds in multiple regions, with models indicating improvement from Tuesday as high pressure advances.
