By Drooid · · How we work
Core Event
On the evening of October 14, 2026, a torrential downpour swept across Istanbul, inundating homes, businesses, roads and underpasses. Floodwaters stranded vehicles on highways, halted traffic and forced the city’s governor to suspend in-person schooling for October 15 and place certain public-sector employees on administrative leave. No serious injuries were reported, but the storm claimed lives and triggered a massive emergency response.
Background & Context
Meteorological agencies identified the precipitation as the heaviest the metropolis has seen since 1985.
Data & Statistics
- Rainfall totals: Beykoz recorded 242 mm (IMM); Eyüpsultan 190.5 mm; Sariyer 187.9 mm. Some reports cite 269.5 mm in Beykoz.
- Casualties: Local media reported two deaths – a 14-year-old electrocuted in Fatih and a 34-year-old who slipped in Sariyer. The governor’s office later announced three deaths, adding a victim found in Kagithane.
- Emergency calls: 2,518 weather-related reports, including 1,277 flooding incidents, 15 landslides, and 47 stranded persons.
- Rescues and deployments: About 8,000 personnel and 2,000 vehicles were mobilized by AFAD, IMM and district municipalities. Roughly 600 people were evacuated from flooded workplaces, and 200 night-shift workers were rescued from Ayazaga.
- Transportation impact: Motorcycles were barred, several cable-car lines and tram services were suspended, and 46 flights were diverted.
Official Statements & Responses
- Governor Davut Gül urged residents to stay home unless travel was essential, advised those in basement apartments to relocate to higher floors, and ordered school closures for October 15 (later extended to Friday).
- Deputy Mayor Nuri Aslan warned that heavy rain would continue, with wind speeds potentially reaching 75–80 km/h, and urged use of public transport, noting metro hours were extended to 02:00.
- Interior Minister Mustafa Ciftci reported that more than 2,700 people had been safely evacuated citywide.
- IMM highlighted that rainfall levels approached the city’s historical maxima, prompting ongoing monitoring from its Disaster Coordination Center (AKOM).
On-the-Ground Reports
Rescue teams used boats, trucks and minibuses to extract stranded workers and evacuate residents from flooded basements. Firefighters rescued a woman swept away in Esenyurt, and crews cleared a collapsed road section in Eyüpsultan. Floodwaters entered two hospitals and the Haciosman metro station, while a retaining wall collapsed at a primary school in Sultangazi without injuring students. Public transport saw surges in ridership as commuters avoided private vehicles.
Conflicting Reports & Gaps
- Death toll: Most outlets reported two fatalities, whereas the governor’s office later announced three deaths, citing an additional victim in Kagithane.
- Exact rainfall measurements: Sources differ on the highest recorded amount, ranging from 242 mm (IMM) to 269.5 mm in Beykoz. A unified figure has not been confirmed.
- Long-term impact: Officials forecast continued rain, but detailed assessments of infrastructure damage, economic loss and secondary health effects have not been released.
What’s Next
IMM’s AKOM warned that heavy showers would persist into the coming days, especially on Istanbul’s Asian side and along the Bosphorus. The governor’s office extended school closures to Friday and maintained the motorcycle ban. Residents are advised to remain indoors, avoid flood-prone areas and monitor updates from municipal and national weather services.
