O Instituto Nacional de Meteorologia (Inmet) emitiu um alerta vermelho de "grande perigo" devido a uma intensa onda de calor que atinge a região Centro-Sul do Brasil. O aviso, que indica riscos à saúde e condições climáticas extremas, deve permanecer em vigor até o próximo fim de semana. As áreas sob maior vigilância incluem os estados do Mato Grosso do Sul, Santa Catarina, Paraná e Rio Grande do Sul.

De acordo com as previsões meteorológicas, as temperaturas devem registrar marcas até 5 graus Celsius acima da média histórica para o período em toda a região afetada.

Em diversos municípios, a combinação de alta pressão e baixa umidade fará com que as máximas se aproximem dos 40°C, exigindo atenção redobrada da população e das autoridades de defesa civil.

Riscos à saúde e recomendações das autoridades

O alerta de nível máximo (vermelho) é acionado quando a onda de calor persiste por mais de cinco dias com temperaturas muito acima da média, o que representa risco de hipertermia e agravamento de doenças cardiovasculares e respiratórias.
