Water invades the street in the North Zone of Porto Alegre with the rise of the Guaíba The level of the Guaíba and the Jacuí Delta continues to rise this Friday (31), causing the first floods in Porto Alegre. The situation occurs amid flooding in the main rivers of Rio Grande do Sul and precedes the arrival of a cold front on Saturday (1st), which brings forecasts of storms and winds of up to 100 km/h. At 7:15 am, the measurement by the Geological Survey of Brazil (SGB) showed 2.52 meters at Cais Mauá. There is a technical divergence about the parameters in the region: the Civil Defense of Porto Alegre considers the alert level to be 2.50 meters, while the SGB sets the mark at 2.60 meters. ?

On Rua João Moreira Maciel, under the new Guaíba bridge, water from the Jacuí River leveled with the road and caused flooding. The water also returns through drains, blocking one of the lanes and making vehicle traffic difficult. As a preventive measure, the Civil Defense of Porto Alegre installed command posts with tents on the islands of Pintada, Marinheiros and Flores, in addition to the Serraria neighborhood, in the South Zone. The Municipal Department of Water and Sewage (Dmae) reported that there is no forecast of closing the flood protection system floodgates, as current forecasts do not indicate that the Guaíba will reach the flood level of 3 meters in the protected area. The closing protocol only begins when the ruler reaches 2.84 meters. Situation of rivers in RS According to the SGB and the Hydraulic Research Institute of the Federal University of Rio Grande do Sul (IPH/UFRGS), the propagation of flood waves keeps levels high. The RS Civil Defense Monitoring Center indicated a very high risk of flooding for the Ilhas region, in Porto Alegre, and issued a red alert for the Sinos river, between Campo Bom and São Leopoldo. The rivers Uruguai (in Itaqui and Uruguaiana), Jacuí (from Dona Francisca), Taquari (from Lajeado), Caí (from São Sebastião do Caí), Sinos (from Taquara) and Gravataí (from Gravataí) are above the flood level. In the Taquari, Caí, Sinos and Gravataí basins, levels rise in the lower reaches, while the upper parts are already showing a downward trend. The exception is the Jacuí River, which continues to rise in the upper reaches, contributing to the increase in the volume of water reaching the Metropolitan Region. Change in weather Friday is marked by firm weather and heat in the state, with temperatures that can exceed 30°C in Porto Alegre, the Metropolitan Region, Missões, Oeste, Centro and Vales. On Saturday, the advance of a cold front changes the weather. The rain starts at dawn in the West and in the Campaign, advancing to the other regions throughout the day. The Metropolitan Region is expected to record showers between the afternoon and evening. The National Institute of Meteorology (INMET) published storm warnings valid for Saturday.
