Heavy rainfall is expected across the country on Thursday, announced Egypt's Meteorological Authority, with floods in the Sinai Peninsula, the Red Sea mountain range and Upper Egypt, state news agency MENA reported.

Egypt was struck by a heat wave of scorching daytime weather and warm nights, with temperatures as high as 40 Celsius (104 Fahrenheit) recorded on Sunday.

On Thursday, however, temperatures in Cairo are expected to drop to a highest of 22 Celsius and lowest of 14 Celsius.

Following heavy rain and floods that poured shortly after sandstorms in March, Head of the Meteorological Authority Ahmed Hussein said the country had not witnessed such inclement weather in 20 years.

March's unstable weather resulted in major traffic accidents that left 16 dead, while the roof of Hurghada Airport on the Red Sea partially collapsed due to rainstorms.
