Landslides, rains and floods: see if your state is on red alert

The National Institute of Meteorology (Inmet) has placed five Spanish states on red alert and another 18 on orange alert due to the accumulation of heavy rains forecast for the next few days. Alerts are valid from 29/11 to 5/12.

The agency states that “significant rainfall is expected in much of the country, considering a range from the northwest of the North Region, central areas and extreme south of Bahia to the east of the Southeast and South regions, which occurred mainly due to the action of a episode of the South Atlantic Convergence Zone (SACZ) at the beginning and during the week, where a channel of humidity persists contributing to the occurrence of rains”.

Risk in each region of Brazil

Inmet issued rain alerts for each region of the country. See each of them below:

For the North Region, rainfall accumulations greater than 20 mm are forecast in much of the region, highlighting the central and eastern areas of Amazonas, central and southern Pará and Tocantins and north of Roraima, where accumulations greater than 80 mm may occur. . In areas of Roraima, west of Acre and south of Amapá, accumulations must not exceed 10 mm.
In the Northeast Region, the highest accumulated rainfall will be concentrated in areas of the center-south of Bahia, in addition to areas of MATOPIBA (Maranhão, Tocantins, Piauí and Bahia), volumes that may exceed 80 mm. In the northern part of the region, in the central part of Ceará, Rio Grande do Norte and Paraíba, the occurrence of isolated showers, mainly due to the heat and high humidity, cannot be ruled out throughout the week.
In the Midwest, there is a forecast of significant rainfall in most of Mato Grosso, on the border of Goiás, Federal District, accumulated that may exceed 70 mm. In a large part of Mato Grosso do Sul and southwest of Mato Grosso, showers may occur due to instabilities caused by a hot and humid air mass in the middle of the week. In the other areas, accumulated rainfall between 20 and 50 mm are forecast.
In the Southeast Region, a humidity channel may favor large accumulations of rain at the beginning of the week, greater than 50 mm. In areas in the southeast of São Paulo, south and northeast of Minas Gerais and Espírito Santo, accumulations may exceed 80 mm. In the west of São Paulo and central-west of Minas Gerais, the accumulated values may be between 30 and 70 mm.
As in the Midwest and Southeast regions, the areas of instability associated with the moisture channel could cause large accumulations of rain in the east and south of the South Region, volumes that could exceed 80 mm in the southwest of Rio Grande do Sul, and east from Paraná and Santa Catarina. In other areas, rainfall volumes between 20 and 50 mm are forecast.
