Strong Winds and Cold Front to Impact Southeast Brazil

A cold front and an extratropical cyclone are bringing strong winds and falling temperatures to Southeast Brazil on Friday, September 21. The National Institute of Meteorology (Inmet) issued an orange danger alert for windstorms affecting the coast of Rio de Janeiro and the north coast of São Paulo. Wind gusts in these areas are expected to range between 60 km/h and 100 km/h, posing risks of falling trees and structural damage to homes and crops. In the city of Rio de Janeiro, gusts could reach 90 km/h, starting in the Costa Verde region before moving to the metropolitan area. In São Paulo, the city may see gusts up to 45 km/h, while some southern interior regions could experience winds up to 90 km/h. The weather system is also bringing isolated rain to parts of São Paulo, Rio de Janeiro, and southern Minas Gerais. Temperatures are expected to drop over the weekend, with minimums in São Paulo potentially reaching 11 degrees Celsius by Sunday. In the interior of São Paulo, low humidity remains a concern, with some areas recording levels as low as 11 percent, increasing the risk of forest fires. The cold front is also affecting the South and Center West, where temperatures are dropping in states such as Mato Grosso do Sul.
