Chapecó, Brazil

The city of Chapecó (Santa Catarina state) found itself at the epicenter of a powerful storm caused by an extratropical cyclone. Heavy rainfall led to widespread flooding; in several parts of the city, streets effectively turned into raging rivers. Torrents of water inundated roadways, blocked traffic, and entered dozens of private homes. Amidst the general flooding of city streets, localized infrastructure damage was also reported. Specifically, in the Pinheirinho neighborhood, walls collapsed due to soil erosion, after which a wave of mud flooded a garage and damaged 12 vehicles.
