A heatwave gripping Central Europe is set to peak in Austria on Friday, with temperatures in urban areas expected to reach 35°C, the national weather service confirmed on Sunday. Meteorologists at *Zentralanstalt für Meteorologie und Geodynamik* (ZAMG) warned that the high-pressure system driving the heat will be punctuated by intermittent thunderstorms, particularly in the Alpine regions, where flash flooding remains a risk.
The heatwave, which began building mid-week, has already disrupted transport links. On Sunday, a lightning strike near Erkner forced the suspension of S-Bahn services, leaving commuters stranded . In Rotterdam, a transformer fire in the Zuid district cut power to nearly 20,000 homes and businesses, paralysing traffic signals and public transport . Meanwhile, Sweden’s meteorological agency, SMHI, forecast a sharp shift ahead of Midsommar, with humid, energy-rich air masses triggering severe thunderstorms by the weekend .
In Finland, where Juhannus celebrations loom, forecasters are still debating whether the summer solstice will bring the traditional bonfires and sunshine or a repeat of last year’s torrential rains . Estonia’s rail operator, Elron, has already switched to summer timetables from Monday, increasing services between Tallinn, Narva, and Kloogaranna to accommodate holiday travel .
Climate scientists caution that the erratic pattern—oscillating between record heat and violent storms—reflects broader shifts in European weather systems. “We’re seeing a more volatile jet stream, which is amplifying both heat domes and convective activity,” said Dr. Lisa Bauer, a climatologist at the University of Vienna. “This isn’t just a one-off; it’s part of a trend we’ve observed over the past decade.”
Public health officials in Austria have issued heat advisories, urging residents in Vienna, Graz, and Linz to limit outdoor activities during peak afternoon hours. Hospitals in the Tyrol region reported a 15% increase in heat-related admissions on Saturday, primarily among elderly patients. “The body’s ability to regulate temperature becomes compromised at these levels,” warned Dr. Markus Reiter of Vienna General Hospital.
As the week progresses, meteorologists expect the heatwave to ease slightly by Sunday, though temperatures will remain above seasonal averages. The thunderstorms, however, are forecast to intensify, with the potential for localized flooding in southern Germany and northern Italy. For now, Austrians are advised to stay hydrated, check on vulnerable neighbours, and prepare for sudden weather changes.
