The torrential rains which have affected the south of Brazil for several days and the rising waters have left at least 37 dead and 74 missing. The regional capital, Porto Alegre, was hit in turn. The task of rescuers is formidable, with entire towns practically cut off from the world, made inaccessible by the floods which devastated the state of Rio Grande do Sul, where it is expected to rain at least until Sunday.
Housing areas drowned as far as the eye can see, roads destroyed or bridges swept away by the current, not to mention the failure of dams which risk further aggravating the situation: the human and material damage is considerable and especially concentrated in the central region of this State.
In Porto Alegre, the regional capital with some 1.5 million inhabitants, the disaster will be ” unprecedented “, warned the governor, Eduardo Leite. On Friday, streets in the historic center of the city were in turn invaded by water due to the exceptional flood of the Guaiba, a River in southern Brazil. The authorities estimate that the level of Guaiba could reach 5 meters in the coming hours. The historical record, dating from 1941, is 4.71 meters.
