Flights departing from Cairo have been delayed due to bad weather, with rain flooding streets across the capital and obstructing traffic.

At least eight flights set to depart from Cairo International Airport to several Arab countries have been delayed due to bad weather conditions and low visibility, airport sources told Al-Ahram Arabic news website.

The flights were bound for Saudi Arabia, Oman, Kuwait, and the UAE.

Authorities have dispatched vacuum trucks to remove rainwater from the streets in downtown Cairo, Nasr City, Maadi, and the fifth settlement.

Temperatures are expected to drop across the country on Friday, with rain forecast in the capital and the Nile Delta. Heavy rain and thunder are expected along the country's northern coast.

Cairo and the Nile Delta are expected to see highs of 15 degrees Celsius and lows of 8. The Mediterranean city of Alexandria will see the same highs with slightly warmer lows of 11.

The country's usually warmer south is expected to be just as cold, with highs of 15-18 and lows of 7-8 expected in Upper Egypt.
