The week that begins this Monday, the last of spring, is expected to continue with rain across the country. Throughout the day, for example, there are storm warnings in Rio Grande do Sul and intense rain in much of Brazil.
According to Climatempo, storms are “gaining strength again” due to the unstable weather. “The combination between the advance of a new cold front in southern Brazil, the action of a low pressure area and the excess heat and humidity in the atmosphere favors the formation of heavy clouds, intense rain showers and thunderstorms in different regions,” he says.
According to MetSul Meteorologia, in the next ten days the rains are expected to maintain “a pattern typical of the summer months, with widespread precipitation and an organized humidity channel from the center to the north of the Brazilian territory, where the greatest volumes of precipitation are expected to occur.”
Until 11 p.m. this Monday, the National Institute of Meteorology (Inmet) maintains a yellow alert for storms throughout the state of Rio Grande do Sul. Rainfall between 20 and 30 mm/h or up to 50 mm/day, intense winds of 40 to 60 km/h and hail are expected.
There is a small risk of power outages, crop damage, falling tree branches and flooding.
“In the south of the country, the cold front is advancing and causing rains in a large part of the region. In Rio Grande do Sul, especially in the west and interior of the state, moderate to heavy rains are forecast, with high volumes and the risk of storms,” says Climatempo.
In case of gusty winds, Inmet advises not to shelter under trees, as there is a risk of falling and electric shocks, and not to park vehicles near transmission towers and advertising signs.
Until 10 a.m. this Monday there is also a yellow alert for intense rains that covers the entire Northern region, with the exception of Roraima, in addition to the entire Central-West region, the entire Southeast region and the northern half of the State of Paraná.
Rainfall of between 20 and 30 mm/h or up to 50 mm/day is expected, as well as intense winds of 40 to 60 km/h, with a low risk of power outages, falling tree branches, flooding and electric shocks.
However, in some areas of the northern, central-western, southeastern and northern regions of Paraná, the alert is orange, indicating heavier rains. This area includes the capitals Porto Velho, Manaus, Cuiabá, Goiânia and Belo Horizonte.
In these localities, precipitation of between 30 and 60 mm/h or between 50 and 100 mm/day is expected, in addition to intense winds of 60 to 100 km/h, with risks of power cuts, falling tree branches, floods and electric shocks.
In these cases, Inmet recommends cutting off, if possible, electrical appliances and the general energy supply. Further information can be obtained from Civil Protection (telephone 199) and the fire brigade (telephone 193).
There is also a yellow alert for low humidity, valid until 10 a.m., for part of the Northeast region, covering areas in the states of Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe and Bahia.
Relative air humidity is expected to be between 30 and 20%, with a low risk of forest fires and health damage. Inmet recommends drinking plenty of fluids, avoiding physical exhaustion during the drier hours, and avoiding sun exposure during the hottest parts of the day.
