The formation of an extratropical cyclone in the southern region of the country leaves the state of São Paulo with forecasts of storms from this Tuesday (9) until at least Thursday (11).
This is why the State Civil Defense issued an alert this Monday (8) indicating very intense rains with large accumulations and also strong wind gusts of up to 90 km/h, mainly in the eastern municipalities of the state, which includes Greater São Paulo, the capital, the entire coast of São Paulo and the Paraíba Valley, Campinas, Sorocaba and Serra da Mantiqueira. Indeed, in these regions, cumulative precipitation will also be significant.
“On Tuesday (9), the peak will be rain, which will appear in the form of thunderstorms. On Wednesday (10), the peak will be winds. Gusts can reach up to 90 km/h. Winds of this intensity can fell trees, demolish buildings and collapse fragile metal structures,” explains Lieutenant Maxwel.
“Do not under any circumstances cross flooded or flooded streets. It is very dangerous and you could end up being swept away. For those who live in risk areas, be careful. Pay attention to the signs of landslides. And in case of emergency, call the Civil Defense, at 199, or the Fire Brigade, at 193”, he added.
With this scenario, temperatures are expected to drop across most of the region. In the capital, Climatempo predicts that the day will see a slight variation in temperature, with a maximum reaching 23°C, while the minimum will be around 20°C.
Climatempo also produced a map on Tuesday showing the areas most exposed to storms, as some are expected to receive a greater volume of rain than others.

This region is the northern part of Greater São Paulo, the Ribeira Valley, the region of Sorocaba, Itapetininga, Avaré, Ourinhos, Bauru, Piracicaba, Campinas, Bragança Paulista, Serra da Mantiqueira, São Carlos, Mococa, Ribeirão Preto en Franca.
