A significant weather shift is on the horizon for the northwest region of São Paulo state, Brazil. A powerful polar air mass is forecast to sweep into the area starting Sunday, October 10th, bringing a dramatic drop in temperatures that will give the region a distinct winter feel.
According to the Institute of Meteorological Research (IPMet) at Unesp in Bauru, the weekend will begin with unstable conditions across São Paulo due to an approaching cold front. This front is expected to bring increased cloud cover and areas of rain with isolated thunderstorms.
The temperature decline will start to become noticeable on Saturday night, October 9th. However, the most significant plunge is anticipated for Sunday with the full arrival of the polar air mass. Forecasts indicate minimum temperatures could reach as low as 9°C in the city of Araçatuba.
The São Paulo State Civil Defense has already issued an alert for the drastic weather change. The system is also expected to generate strong wind gusts, with speeds forecast between 50 km/h and 70 km/h affecting Araçatuba and other surrounding regions.
For residents accustomed to the typically hot conditions of the Noroeste Paulista, the upcoming days will feel like a sudden onset of winter. The combination of falling temperatures and high winds will create a sharp contrast to the usual climate.
The weather pattern is a clear reminder of the seasonal shifts that can impact the region. Authorities are advising the public to be prepared for the colder conditions and to take necessary precautions against the strong winds.
