Central Brazil is experiencing periods of intense heat and critically low humidity. In Goiás, temperatures have reached up to 39°C, with relative humidity dropping to 15% in the afternoons. The combination of high temperatures, dry air, and wind has placed approximately 120 municipalities under critical wildfire risk due to the ‘30-30-30’ factor.

Similarly, Mato Grosso do Sul is facing extreme conditions as a cold air mass weakens. Temperatures in the Pantanal and northern regions are expected to exceed 40°C, while humidity levels are projected to fall between 10% and 30%. Authorities in these regions have warned of increased forest fire risks and advised residents to increase water intake.
