Istanbul’s worst floods in 80 years leave four dead

By the Editorial Team · Saturday, October 17, 2026

Istanbul experienced its most severe flooding since 1942, resulting in at least four deaths and widespread damage across the city due to unprecedented rainfall over two days. Authorities have deployed thousands of personnel for recovery efforts while warning of continued heavy rain, highlighting concerns about urban development's role in worsening the disaster amid escalating climate change impacts.

Istanbul has been struck by its worst flooding in more than eight decades, officials said Friday, as the death toll from the unprecedented rains rose to four. The city, home to approximately 16 million people, experienced rainfall over a 48-hour period that exceeded the combined average precipitation for September and October, according to Turkey’s state-run Anadolu Agency.

Interior Minister Mustafa Ciftci described the event as the most severe flood disaster since 1942 during a visit to one of the hardest-hit neighborhoods in the Sariyer district. A 66-year-old man’s body was recovered Friday beneath a bridge in Sariyer, adding to the three previously reported fatalities. Among those who died was a teenager who was electrocuted amid the storm.

The flooding led to widespread inundation of homes, businesses, streets, and parks throughout the city. Vehicles were swept away by the torrents, with some ending up piled at the bottoms of hills. Prior to the discovery on Friday, authorities reported that four individuals remained missing. The Interior Ministry noted nearly 9,850 damage reports and related emergency calls. In response, about 46,000 personnel have been deployed to assist with debris removal and support residents affected by the flooding.

The General Directorate of Meteorology issued warnings of continued "heavy and intense" rainfall expected over the weekend for Istanbul and adjacent provinces, raising further concerns about additional flooding risks.

Accompanying Ciftci on his visit was Murat Kurum, Turkey’s minister for environment, urbanization and climate change. Kurum acknowledged that urban development near waterways had contributed to the severity of the flooding and emphasized the importance of addressing this issue. Speaking in light of Turkey’s upcoming role as host of the United Nations climate change conference COP31 in Antalya next month, Kurum linked the disaster to broader climate change impacts, stating, "Combating climate change is not a choice, but a necessity."

The authorities continue efforts to manage the aftermath and prepare for ongoing adverse weather conditions, underscoring the challenges Istanbul faces as it confronts extreme weather events intensified by environmental and urban factors.
