Greece is bracing itself for an African heatwave starting from Thursday, when temperatures are expected to reach over 42-43 degrees Celsius. The heatwave is similar to the great heatwave of 2007, according to meteorologist Giannis Kallianos. The hot air masses will reach the whole Mediterranean basin, as well as parts of Turkey, while it will also extend to northeastern parts of Europe affecting Russia. Temperatures are expected to reach 39 degrees Celsius on Monday and Tuesday in Greece, according to the forecasts, while things will get even hotter from Thursday till next weekend once the hot aerial mass lands in Greece. Mr. Kallianos warned that the National Meteorological Services and competent state services should issue a timely warning to citizens.
