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.

Torrential rains have struck the city of Split and other parts of Dalmatia. The situation was particularly severe in the Trstenik district. According to local weather stations, some areas of Split received more rainfall in a single hour than the monthly average (ranging from 40 to 77 mm). The rainfall was so intense that the city's storm drainage system could not handle the volume of water. Water levels on the streets rose significantly; vehicles struggled to move, and pedestrians had to literally wade through the torrents. In some locations, the force of the water dislodged manhole covers. The heavy rain affected not only Split but also other parts of Dalmatia, with thunderstorms and downpours hitting the Kaštel and Sinj areas, as well as other towns in the region. Footage from Brdo captured the peak of the storm in Split, with wind gusts reaching approximately 95 km/h.
