Following a hot and sunny carnival, a cold front is changing the weather across much of Brazil starting Thursday, marking a shift towards a more unstable atmosphere. While maximum temperatures in various capitals remain between 28°C and 32°C, increased humidity and heat during the afternoon will contribute to the formation of heavy cloud cover, leading to sporadic showers that may intensify in some areas.

As the weekend approaches, the instability in the weather is set to rise, particularly in regions such as Espírito Santo, northern Minas Gerais, and parts of the Central-West like northern Goiás and northern Mato Grosso. Forecasts indicate significant rainfall, with some places in the North region, including Macapá and Manaus, expected to receive over 100 mm of rainfall in the coming days, creating potential risks for flooding and other weather-related hazards.

Overall, the forecast points to a transition from the carnival's sunny celebrations to a wetter and stormier atmosphere over the weekend. This shift signals the need for preparedness in affected regions as the increased rainfall could lead to challenges in infrastructure and safety as communities adapt to the changing weather patterns.
