Four people are dead, and 19 other injured, after gales slammed Istanbul on Monday.
According to the Istanbul Governor's office, one of the four casualties was a foreign national, while three of the injured are in critical condition.
Turkey's Meteorology General Directorate reported that winds of up to 130 kilometers per hour hit the city, with wind ripping off roofs and tearing down signboards, while rising sea water also flooded streets.
The intense wind also caused at least two lorries to overturn, blocking traffic on a busy highway in the city, while a clock tower in the Catalca district collapsed.
The wild weather also disrupted air traffic, with six Turkish Airlines planes unable to land in Istanbul, and instead being rerouted to Ankara and Izmir.
Officials say the strong gusts are expected to continue into Tuesday afternoon.
