Experts the Egyptian Meteorological Authority (EMA) forecast hot weather to prevail on Saturday in the greater Cairo, the Delta and northern eastern coasts looking over the Mediterranean Sea.\r\n\r\nIt will be very hot in Upper Egypt and surrounding areas up to the border line with the Sudan.\r\n\r\nIt inclines to be cold at night in Cairo, the Delta and the middle section of the Sinai Peninsula.\r\n\r\nHowever, it will be nice weather at night in the south part of Sinai, the range of mountains of the Red Sea, north and Upper Egypt.\r\n\r\nThe experts warn of dust-laden strong winds blow up in northern eastern coasts, the greater Cairo.\r\n\r\nWinds become stormy in some parts of the northern western coasts but they will be moderate over the most parts of the country.\r\n\r\nThe Mediterranean Sea witnesses rough conditions, the waves swell to 2-3 meters and the surface southerly eastern winds blow up there.\r\n\r\nOn the other hand, the Red Sea sees moderate conditions, the waves swell to 1,5-2 meters and the westerly northern wind blows up there.\r\n\r\nMajor temperature degree in Cairo and its surroundings will be 35 Celsius over the hours of the daytime, the minor degree will be 20 C at night.\r\n\r\nOn the other hand, the experts warn of the \u00a0Coronavirus pandemic may affect the accuracy of the initial weather forecast model output originating from national and global weather prediction centers because of a cutback in the number of aircraft flights that generate vital weather data, according to the European Centre for Medium-Range Weather Forecasts (ECMWF) and other experts.\r\n\r\nThe aircraft collect temperature and wind data, among other information, that help improve the initial atmospheric conditions that drive global and regional weather forecast models. This data is used routinely to improve the forecasts created by national weather prediction centers across the globe.\r\n\r\nHowever, the pandemic has drastically reduced the number of such flights in Europe and increasingly in the U.S. This impact will be a reduction in global forecast performance. For regional models, the impact may be even greater.\r\n\r\nRegional models have the ability to resolve high-impact weather, such as thunderstorms, said AccuWeathers Scott Mackaro, vice president, Science, Innovation & Development. Information about the vertical structure of the atmosphere is vital and already sparse. Aircraft measurements provide just that.
