MetSul Meteorologia warns of a lot of rain in the south of Rio Grande do Sul between Tuesday (1) and Wednesday (2).
A semi-stationary front over the state begins to gradually retreat south towards Uruguay, pressed by very hot air advancing from the north. With the feeding of the tropical air, the activity of the frontal system increases a lot this Tuesday and tomorrow over the South of the State and Uruguay, bringing high volumes of rain that will be between 50 mm and 100 mm in several points, but that must be even higher in some places.
The map shows the projection of accumulated rainfall until 9:00 am in the MetSul WRF model, where the trend of high volumes is observed in the south of the state.
This Tuesday, the rain also affects parts of the West and East of the State, but on Wednesday, these regions should have a decrease in cloud cover and the presence of the sun with strong heating due to the entry of hot air with a stream of current at low levels . of the atmosphere.
It happens that even on Wednesday a cyclone forms in the Prata region and the associated cold front begins to turn in the opposite direction, bringing rain in the west of Rio Grande do Sul until the end of the day and for the other regions on Thursday.
This front, when crossing Rio Grande do Sul on Thursday, will bring very irregular rains and with little accumulation of rainfall in most of the localities. The risk in the front passage will be strong wind, and gale is not ruled out.
