Egypt's meteorologists predict a slump in temperatures nationwide as well as rainfall in some parts on Friday, saying weather conditions will improve Saturday.
High temperatures in the capital Cairo and the Nile Delta are expected to stand at 18 degrees Celsius (64 Fahrenheit), with lows of 13 C (55 F).
Windy weather in the country's southern governorates will trigger sands and dust, obscuring vision on roads and obstructing navigation, state news agency MENA reported. Some parts of the country have already seen dusty weather since Thursday.
Rainfall is forecasted in some parts of the capital, northern coasts and Delta governorates.
The Mediterranean city of Alexandria will see slightly colder weather, with a high of 17 C (62 F) and a low 9 C (48 F).
High waves and winds along the Mediterranean will result in rough waters for navigation.
Spokesman for the Alexandria Port Authority Reda El-Ghandor said Friday that two ports in the city remain shut down for the second day in a row due to the bad weather.
Rainfall continued in the coastal city Friday, a few days ahead of a severe storm and a wave of heavy rains expected to last for six days.
Four Red Sea ports were also closed off early Friday due to the harsh conditions, the transport ministry said in a statement.
