Cairo and some port cities were swept by a sandstorm on Sunday, with a yellow cloud descending on several regions and strong winds and heavy dust forcing the closure of several ports.
The Red Sea Port Authority closed Port Tawfik and Zeitiyat at noon after the sandstorm affected visibility levels.
The port of Adabiya in Suez governorate has also been also shut, the General Authority for the Suez Canal Economic Zone said. The Ain Sokhna port, in the same governorate, reopened earlier on Sunday after an hours-long closure due to the bad weather.
The weather is expected to clear and temperatures will drop in the evening, head of the Egyptian Meteorological Authority Mohamed Shahin said in TV comments.
Temperatures will further decline in the coming days, Shahin added, advising people against wearing light clothes.
Cairo and the Nile Delta will see highs of 26 degrees Celsius and lows of 6 on Monday, while Alexandria and cities along the Mediterranean will see highs of 22 degrees and lows of 14.
