Istanbul Municipality's Disaster Coordination Center

Heavy downpours and local thunderstorms have wreaked havoc in Istanbul, causing traffic disruptions and bringing daily life to a standstill.

Heavy rains first gripped Istanbul on Sept. 15, causing puddles to form on the city's streets. Scores of pedestrians sought shelter under business awnings and the downpour caused traffic to slow down significantly.

Heavy rain and flooding wreaked havoc in Istanbul, Türkiye's largest city, hitting the north of the province particularly hard on Aug. 27.

The Meteorological Service has issued a storm warning for several provinces in Turkey's Marmara region.

The strong wind is expected to hit the provinces of Istanbul, Edirne, Kırklareli, Tekirdağ, Kocaeli, Sakarya and Yalova starting this morning.
