Yesterday, when the thermometers reached 38.4 ° C, on the hottest day in the history of Belo Horizonte, the neighbors were surprised by the wind and rain in some parts of the capital.

It rained in Ouro Preto and Mariana – we had heavy rains in these places and also in Manhumirim, Manhuau and Alto Jequitib. We also had hailstorms in the Zona da Mata. This is due to the heat and availability, the famous summer rains that occur in the late afternoon, ”said the meteorologist.

The hot air mass continues to act in the state. These rains that occurred today (yesterday) were only occasional, ”he said.

According to Ruibran dos Reis, today there is the possibility of the so-called “summer rains” in the south of Minas and in the regions of Campo das Vertentes, Zona da Mata and in the central region of the state. He said that more intense rains capable of causing a drop in temperature can only occur from Sunday, “with the arrival of a cold front.”

In two municipalities of the Metropolitan Region of Belo Horizonte, the heat is aggravated by the lack of water in homes and commercial establishments. The problem started in September but got worse in the last week. In Pedro Leopoldo, the neighborhoods in the northern region of the city have been without continuous supply for five days. The attorney general of the municipality, Cristiano Fonseca Pereira, reported that the municipal administration filed a Public Civil Action on Tuesday against the Companhia de Saneamento de Minas Gerais (Copasa), in which it demands the immediate restoration of the continuous supply of water in the city. City. In Lagoa Santa, in several houses of the Mirante do Fidaldo condominium, only air passes through the water register. Copasa reported that the supply cuts in RMBH are “specific.” However, the Company admitted that, at some points, the system is overloaded, which makes the supply irregular. According to Copasa, this is more common in the highlands.
