Meteorologists say Egypt will witness unstable weather for three days starting on Friday.
Temperatures nationwide are forecasted to slump by 4-5 degree Celsius (39-41 Fahrenheit), with higher chances of rainfall, mainly in northern cities, the spokesperson for the Egyptian Meteorological Authority (EMA) Wahid Saudi said.
Saudi also warned of thick morning fogs that will obscure vision on highways.
However, higher water levels due to wind and possible rain are not expected to affect navigation in the Mediterranean and the Red Sea.
Temperatures on Friday are forecast to reach a high of 21C (70F) in Cairo, 20C (68F) on the north coast and 21C in the southern flank of the country. Lows are predicted to hover around 12C (54F).
