Heatwave grips Greece, temperatures to exceed 42C with 'Libas' phenomenon

Greece is facing a significant heatwave, with the National Meteorological Service issuing an emergency bulletin predicting temperatures to soar above 40 degrees Celsius (104 Fahrenheit) across much of the country on Wednesday, July 22. The mercury is expected to reach 41-42 degrees Celsius in central and southern mainland areas, and potentially as high as 43 degrees in Thessaly.

The intense heat is attributed to a very hot air mass originating from North Africa. This will be further exacerbated by the 'Libas' phenomenon, a hot and dry wind that descends from the Pindus mountains, accelerating and heating up as it moves east. This wind is expected to drastically lower humidity levels, increase thermal stress, and significantly raise the risk of fires.

Eastern mainland regions, including Thessaly, Sterea Ellada, and the eastern Peloponnese, are forecast to experience the highest temperatures, with some areas possibly exceeding 42 degrees Celsius. In Attica, temperatures are predicted to range from 25 to 41 degrees Celsius, while Thessaloniki will see partly cloudy skies and temperatures up to 35 degrees Celsius.

In response to the extreme conditions, the Ministry of Labor and Social Security has announced mandatory work stoppages for outdoor laborers from 13:00 onwards. The emergency bulletin is scheduled for an update on Wednesday morning as forecasters monitor the evolving weather patterns. Citizens are advised to stay informed through the Hellenic National Meteorological Service website and Meteoalarm warnings.
