The weekend will see heavy rain in the Southeast Region

Next weekend (20 and 21/01), the National Institute of Meteorology (Inmet) warns of an increase in moisture convergence in the middle/lower layer of the atmosphere over the east of the Southeast Region due to the intensification of an area of ​​low pressure, which will give rise to a cold front over the Atlantic Ocean.

This atmospheric pattern, combined with the behavior of winds at high levels and high temperatures in the region, will increase instability, between Saturday (20) and Sunday (21), over the east of São Paulo, south, Zona da Mata and center ( including the capital and Metropolitan Region) of Minas Gerais and Rio de Janeiro.

On Saturday, Inmet's forecast indicates that the area most affected by the highest daily rainfall accumulations should be the eastern part of São Paulo (including the capital and Metropolitan Region) and coastal areas, as shown in figure 1a, where some totals of Rainfall can vary between 80 millimeters (mm) and 100 mm in a localized manner. On Sunday, the heaviest rains will occur between the north coast of São Paulo and areas of the south, east (including the capital and Metropolitan Region), the mountains of Rio de Janeiro and the Zona da Mata of Minas Gerais, where it may rain between 70 mm and 90 mm in some points.
