The Egyptian capital Cairo and other parts of the country are witnessing warm daytime temperatures on Tuesday, but forecasters say the mercury will drop by up to 8 degrees Celsius in some areas in the coming two days.

High temperatures are expected to drop to 20 and 21 degrees from 27 in the capital Cairo and the Nile Delta on Wednesday and Thursday respectively, while lows are forecast at 15 C, the Egyptian Meteorological Authority (EMA) said on its official website.

Rain is forecast in cities on the Mediterranean and some parts of the Nile Delta and may extend to Cairo on Wednesday. The wet weather will continue on Thursday on the coast.

The Mediterranean city of Alexandria and other cities on the coast will see highs of 18 and lows of 13 C on both days, a drop of some 6 degrees from Tuesday.

Cities to the south are also predicted to see colder weather, with highs of 20 and 21 in the northern part of Upper Egypt, which includes the governorates of Minya, Fayoum and Beni Suef.

The southern cities of Upper Egypt will be warmer, with highs at 31and 24 on the two days respectively. Lows in both regions are predicted at between 10-13 C on both days.

The EMA said active winds stirring sand and dust in some parts of the country are leading to the disruption of maritime navigation on the Red and Mediterranean seas in the next two days.
