Unstable and windy weather closed Al-Dekhiela and Alexandria ports on the north coast while extremely cold weather was expected across Egypt Thursday.
Egypt's Red Sea Port Authority also said that Sharm El-Sheikh port was closed Thursday due to bad weather.
Other ports are expected to close throughout the day as a preventive measure to maintain the safety of maritime navigation.
Winds carrying sand and dust hit parts of the country starting Wednesday, leading to low visibility and cold temperatures.
