Heavy rainfall triggered flash flooding in Istanbul, Turkey’s largest city, resulting in at least one confirmed fatality involving a teenager. The severe weather caused significant disruption to public services and infrastructure. Local reports indicate that the deluge overwhelmed city drainage systems, leading to water entering hospitals and causing sections of roads to collapse.

Authorities have responded by closing schools and suspending various forms of public transportation to ensure safety as the city grapples with the aftermath of the storm. While the immediate focus remains on emergency response and clearing blocked transit routes, the incident has highlighted vulnerabilities in the city's infrastructure during extreme weather events. There are no reports of further casualties at this time, though cleanup efforts are ongoing as water levels recede in the most affected districts.
