A heatwave is forecast across the country from Wednesday until Friday, the Egyptian Meteorological Authority (EMA) said in a statement late on Tuesday. According to the data released by the EMA on its official website, the rise in temperatures is caused by a high-pressure area in upper atmosphere layers, which is expected to continue until mid-October. Greater Cairo and the Nile Delta region will see a high of 35 degrees Celsius starting Wednesday, rising to 36 degrees Celsius on Thursday before dropping back to 35 degrees on Friday. The northwestern coasts of Egypt will see a peak of 37 degrees on Wednesday. However, the temperature will drop in the region to 30 degrees on Friday. North Upper Egypt will see a heatwave throughout the next three days with highs ranging from 36 to 39 degrees, while Southern Upper Egypt will see highs ranging from 40 to 41 degrees.
