MetSul Meteorologia warns that a cold front will advance through southern Brazil this beginning of the week with more extensive rains and a high risk of storms in the three southern states. The frontal system of strong intensity has already begun to enter Rio Grande do Sul from the West now at the end of this Sunday with the probability of locally heavy to torrential rains and also the possibility of wind storms (gales) and hail, as has already occurred. in Argentina.
The maximum frontal activity of this system must occur in the South West of Brazil. Therefore, MetSul Meteorologia anticipates that the risk of stronger storms is valid for the Western Half of Rio Grande do Sul, the West and Midwest of Santa Catarina and the Western Half of Paraná, despite the possibility of isolated severe weather. . in other areas of the three states.
In Rio Grande do Sul, this Monday, the frontal system brings rains, storms and isolated storms early to the western and southern half. In the East and Northeast of the State, in many areas the sun rises with clouds and dimmer before the weather changes. It will be the case of Porto Alegre, which starts the day with firm and muggy weather, but then it must rain, especially from afternoon to night.
Throughout the second, the front advances and brings rain to all regions. They will be irregular rains, but, in isolation, there are strong blows with the risk of localized storms of strong wind and hail. In the Midwest, after a rainy day begins, the weather improves from evening to night and the sun can appear in many cities in the afternoon.
The rain, although abundant, will be irregular. In many places it should rain less than 10 mm or 20 mm in the passage of this front and it is possible that in a few the precipitation even “fails”, but many places will have rainfall of 20 mm to 30 mm in the passage of the system and in some cities the accumulated can be close to or greater than 50 mm.
This cold front, unlike what is common at this time of year and more normal to see in winter, will be able to advance through the interior of the continent and will arrive with rains and storms, some strong to severe due to wind and hail, the states of Mato Grosso. do Sul and Mato Grosso from Monday to Tuesday. Part of the state of São Paulo may also have rains and storms associated with this front, but the frontal system should weaken as it moves through southeastern Brazil.
Cyclone vortex warning
MetSul anticipates that on Tuesday a cyclonic vortex will form over eastern Rio Grande do Sul with the center of low pressure located in the sea and then move towards the Lagoa dos Patos area. This system will impress the satellite images because the axis of the cyclone will be on the continent and precisely in the eastern part of Rio Grande do Sul, which includes Porto Alegre.
Tuesday’s cyclonic vortex can bring moderate wind and occasional gusts in eastern Rio Grande do Sul, but MetSul does not expect it to be a strong wind generation system. The great risk associated with this system will be intense and voluminous rains with the possibility of flooding in parts of the East and Northeast of Rio Grande do Sul, especially in the Lagoa dos Patos area and its surroundings, the Coast, the valleys, the Greater Porto Alegre and the Serra.
