(MENAFN- Live Mint) (Bloomberg) -- Blistering heat is sweeping across southeast Europe this week, triggering weather alerts and stressing power grids.

A high-pressure system is feeding in a stream of hot air from North Africa, where temperatures in Tunisia are forecast to reach 47C (117F) on Monday. Southern Italy faces high wildfire risks, while highs in Sicily are expected to hit 43C. The Italian island set Europe's current temperature record of 48.8C in 2021.

This June was the warmest on record for Western Europe, with heat waves amplified by an unusually hot western Mediterranean Sea. Climate change is increasing the frequency and severity of extreme weather events on the world's fastest-warming continent.

Greece is also straining under the heat. The Hellenic National Meteorological Service expects temperatures to reach up to 43°C on the mainland and authorities have placed Athens and the wider Attica region on high wildfire alert. There were about 70 wildfires recorded across the country over the weekend.

Greek Energy Minister Stavros Papastavrou convened an emergency meeting Sunday with the country's power grid and distribution network operators to ensure electricity supply remains stable amid surging demand. To protect workers, Greece's labor ministry has mandated a nationwide halt to outdoor labor between noon and 5 p.m. Monday in multiple regions.

Heat across the region is getting a boost from an extremely warm Mediterranean Ocean, where temperatures are 4C above normal, data from the Balearic Islands Coastal Observing and Forecasting System show.

Red heat alerts are also active in Serbia, which could see daytime highs near 39C, according to national forecaster RHMZ.
