A sudden change in the weather left the sky completely dark in Curitiba neighborhoods this Monday morning, accompanied by strong winds and reports of brief power outages. The phenomenon occurs amid weather alerts issued for hundreds of municipalities in Paraná due to the advance of a cold front combined with a low-pressure system.

Advance of cold front and instability in the state

The atmospheric instability is caused by the advance of a cold front associated with a low-pressure system located over Paraguay. The National Institute of Meteorology issued warnings covering 316 municipalities in Paraná, forecasting heavy rains, lightning, and wind gusts that may vary by region.

Forecast of heavy rain and strong winds

In areas stretching from West to East Paraná, significant rainfall volumes and intense winds are forecast, with the possibility of hail. The weather conditions could cause power outages, flooding, crop damage, and fallen trees. In the Metropolitan Region of Curitiba, the warning indicates risks associated with the storms.

Temperature drop and forecast for the coming days

In Curitiba, thermometers marked around 16°C early in the day, with a forecast high of 23°C, while other regions recorded more intense heat before the arrival of the rain. The instability is expected to begin weakening only starting Wednesday, when the forecast points to sunnier days and a gradual drop in temperatures across the state.

Safety precautions and emergency numbers

During strong winds and lightning, the recommendation is to seek a safe location and avoid staying near trees, utility poles, structures that could fall, and open areas. In case of emergency, the population can contact the Fire Department at 193 or Civil Defense at 199.
