Ciclone e frente fria devem trazer chuvas e ventos fortes ao ES
O sistema começa a se formar entre segunda-feira (6) e terça-feira (7), a partir de uma área de baixa pressão entre o Paraguai e o norte da Argentina. Com o avanço de uma massa de ar frio de origem polar, o contraste com o ar quente na região favorece a formação do ciclone extratropical, que deve se intensificar sobre o Uruguai. A frente fria associada a esse sistema avança pelo país ao longo da semana.
Após provocar temporais no Sul do Brasil e em Mato Grosso do Sul nos dias 6 e 7, a frente fria avança para o Sudeste. Na quarta-feira (8), são esperadas fortes pancadas de chuva em áreas de São Paulo, Minas Gerais e Rio de Janeiro.
Já na quinta-feira (9), a instabilidade se espalha também pelo Espírito Santo, com previsão de pancadas de chuva em diferentes regiões do Estado.
