Após um alívio no final de semana com temperaturas mais amenas, a semana começa com uma nova onda de calor pelo país. Já é o oitavo fenômeno do tipo neste ano, segundo o Climatempo.
As regiões Sul, Sudeste e Centro-Oeste devem sentir novamente um calor fora dos padrões nos próximos dias.
Além das altas temperaturas, a tendência é que o ar tenha novamente baixa umidade, o que piora a respiração e facilita focos para incêndios.
A umidade do ar também pode voltar a níveis preocupantes em diversas capitais. A previsão é que a nova onda de calor se estenda até o dia 8 de outubro.
Maiores temperaturas
As maiores marcas nos termômetros devem ser registradas no interior de São Paulo, oeste de Minas Gerais, Mato Grosso do Sul, sul do Mato Grosso e Goiás.
Em algumas capitais, as máximas podem retornar para a casa dos 40°C, segundo o Instituto Nacional de Meteorologia.
Em Campo Grande, os termômetros devem chegar a 40°C já nesta segunda, 30. Em Cuiabá, a previsão é que a máxima atinja essa marca a partir de terça-feira.
No Rio Grande do Sul, depois de uma semana com temporais, o estado deve voltar a ficar em alerta para fortes chuvas ao longo desta semana.
Algumas cidades, principalmente no sul do estado, registraram volumes acima da média para o mês em somente um dia.
E a chuva?
"No Mato Grosso do Sul, todo o Sudeste, e também boa parte dos estados do Sul, a tendência é que a chuva fique dentro da média, ou um pouco acima da média. A frequência de passagens de frentes frias na região deve favorecer esse cenário", afirmou o meteorologista Guilherme Alves, do Climatempo.
O avanço vai das chuvas começar pelo Centro-Sul, no entanto, na maior parte do Nordeste, norte de Minas Gerais e de Goiás, Mato Grosso, Tocantins e Pará, são previstas chuvas próximas e abaixo da média. Enquanto isso, nas regiões sudoeste do Amazonas e do Pará, bem como no norte de Rondônia, as precipitações também devem ocorrer com frequência acima da média.
De acordo com o Alves, a chuva ainda deve permanecer distante das regiões Norte, Nordeste e parte do Centro-Oeste. Nestas áreas, as precipitações devem se manter em torno de 20 a 30 milímetros abaixo do que é esperado para todo o mês de outubro.
