New wind puts the state of São Paulo on alert The passage of a cold front should change the weather in Alto Tietê from this Friday (7). According to Climatempo, all cities in the region are forecast to experience rain showers between the afternoon and evening, as well as gusts of wind that could exceed 50 km/h in several municipalities. The change in weather occurs with the advance of a cold front through the state of São Paulo. Although an extratropical cyclone — which should reach bomb cyclone intensity — forms between Uruguay and Rio Grande do Sul, the system should not pass through the Southeast. Even so, it indirectly influences weather conditions by causing stronger winds and favoring the formation of areas of instability. ?

In areas close to Serra do Mar, gusts can be even more intense. In Alto Tietê, the strongest gusts forecast for this Friday are up to 67 km/h in Salesópolis, 58 km/h in Biritiba Mirim and between 50 km/h and 54 km/h in other cities in the region. Salesópolis may have wind gusts of up to 67km/h, according to forecast Larissa Rodrigues/g1 On Saturday (8), the rain should concentrate mainly during the morning. In the afternoon, the weather tends to gradually clear, but the sky remains very cloudy in much of the region and wind gusts can still exceed 50 km/h in some municipalities. On Sunday (9), the weather becomes more stable, with a predominance of sun between clouds and no rain forecast. Despite this, the sky remains partially cloudy and there is still a possibility of wind gusts between 29 km/h and 39 km/h. Climatempo's forecast indicates that a second cold front, accompanied by a mass of polar air, should advance through southern Brazil during the weekend and cause a more significant drop in temperatures in part of the state of São Paulo from next Monday (10).
