The fog, which was effective in Istanbul during the night hours, continued to affect the city in the morning, particularly around the Bosphorus.
Due to the fog, the 15 July Martyrs Bridge, the FSM Bridge, and the Bosphorus were buried in fog and virtually disappeared from view.

In images captured from the European Side, the other side of the Bosphorus was invisible due to the fog, and visibility for drivers decreased.
