Torrential rain turns streets into fast-moving floodwater in Istanbul, Turkey

On October 27, 2026, in Istanbul, Turkey, @nah_ic_ shared a video showing severe flash flooding during torrential nighttime rainfall on the city's Asian side. In the video, intensely heavy rain pours diagonally beneath a streetlamp as a city street transforms into a muddy river of fast-moving floodwater. The author warned residents to avoid going outside unless they had urgent errands, highlighting the dangerous conditions caused by the downpour. According to reports, a severe autumn storm brought heavy rain, strong winds, and a sharp temperature drop across Istanbul and western Turkey. The Turkish State Meteorological Service issued yellow and orange weather alerts across the Marmara region. Flooding disrupted road traffic, particularly in the Asian-side districts of Pendik and Tuzla, while strong winds also affected flights at Sabiha Gökçen Airport and caused diversions at Istanbul's airports. The storm followed another period of exceptional rainfall earlier in October that had caused widespread flooding and urban disruption.
