At least 5 people, including a foreign national, died and dozens of others were injured after heavy storms hit Turkey’s biggest city Istanbul and its surrounding regions.

Adverse weather conditions prompted a one-day suspension to education for Tuesday in 11 provinces.

In Istanbul, authorities urged citizens late Monday not to go outside unless necessary due to falling objects and clogged roads.

Turkish State Meteorological Service (TSMS) issued an orange-level storm warning for 17 provinces, the second-highest of the four danger levels, and a yellow alert, the third-highest danger level, for 35 provinces. According to the TSMS, more torrential rain and thunderstorms are possible in the Marmara, Aegean, western Mediterranean and western Black Sea regions and the northwest of central Anatolia.

Mud rain was seen in Istanbul in the morning hours due to the storm. Many drivers flocked to car washes to clean their mud-covered cars. According to the TSMS, the speed of the wind reached 129.95 kilometers per hour in the Beylikdüzü district of Istanbul, 62.14 mph in the Adalar district on the Princes" Islands and 49.71 mph around the Bosporus.
