The week will begin with rain in the southern region of Brazil and with the possibility of thunderstorms in the interior of Rio Grande do Sul. There is also a possibility of rain in the north and northeast of the country, while hot and dry air prevails in the southeast and central-west regions .
Rio Grande do Sul will see an increase in humidity after a weekend with clear weather. This happens due to the action of meteorological troughs – wind currents that help to form storm clouds – and low pressure systems that are acting in Argentina and Paraguay.
According to Climatempo, the interior of the state of Rio Grande do Sul is on alert for storms in the coming days. In the northwest and west of Rio Grande do Sul, there is a warning of storms with lightning and gusts of winds of up to 90km/h.
The Civil Defense of Rio Grande do Sul warned, this Sunday (21), of the risk of disruption due to the high volume of rain in the coming days in the west, northwest, close to the center and north of Rio Grande do Sul. Also according to the agency, in these regions, due to persistent rain, accumulations of between 40mm and 80mm are expected, and could exceed 100mm. Civil Defense also stated that it does not rule out storms in these areas.
The North and Northeast of Brazil are also expected to face rain, with a warning on Monday (22) for storms in Amazonas, Pará and Maranhão.
The first rain showers should start in the morning in Amazonas, Acre and the state of Roraima. In Belém and Amapá, it rains at any time. The capital of Pará will have a muggy Monday (22) due to the influence of the ZCIT – Intertropical Convergence Zone. In the northern region, the weather should remain firm in the south of Tocantins, but in the capital Palmas, rain could come heavily in the afternoon.
Also under the influence of the ZCIT, the north coast of the Northeast is expected to experience storms on Monday (22). Rain is expected in São Luís (MA), Teresina (PI) and Fortaleza (CE), and even with the sun shining at times, these regions are once again on alert during the afternoon.
According to Climatempo, there is no rain forecast for the south of Piauí and the west of Bahia. The north coast of Bahia and the capital Salvador have a warning for storms with winds of up to 90km/h.
The beginning of the week will be with little rain and high temperatures in the Midwest. In Campo Grande (MS), Goiânia and Brasília the weather remains steady. The same low pressure system in Paraguay – which affects Rio Grande do Sul – could bring isolated rain to the Pantanal and the south of Mato Grosso do Sul. In Mato Grosso, temperatures reach 34ºC on Monday (22), but it may rain heavily in the afternoon in the center and northern region of the state.
Throughout the southeast, the forecast is for firm weather, with heat in Rio de Janeiro (RJ), Belo Horizonte (MG) and São Paulo (SP). The alert goes to the relative humidity of the air, which should be below 30% in the state of São Paulo – with the exception of the Coast, northwest and Minas Gerais triangle, south of Goiás and central-east of Mato Grosso do Sul. In Vitória, in Espírito Santo, humidity coming from the sea can result in quick and isolated rain showers.
