Berlin: A powerful heatwave that has already brought record breaking temperatures and widespread disruption across Western Europe is now moving east, placing Germany, Poland and other parts of Central Europe under severe weather warnings. Forecasters say the heat is expected to intensify over the coming days, raising concerns about public health, transport, wildfires and pressure on power and water supplies.
Germany experienced one of its hottest days on record on Saturday as temperatures climbed above 41 degrees Celsius in parts of the country. Preliminary data from the German Meteorological Service showed a temperature of 41.3 degrees Celsius near Saarbrücken, close to the French border. Weather officials warned that some areas could see temperatures rise even further, with highs approaching 42 degrees Celsius.
Authorities across Germany urged people to stay indoors during the hottest part of the day, drink plenty of water and avoid unnecessary outdoor activities. Officials also advised residents to check on elderly neighbours and vulnerable people who are more likely to suffer from heat related illnesses. Some local authorities appealed to the public to conserve water as demand increased during the prolonged spell of hot weather.
The heatwave is expected to spread further into Poland over the weekend and into next week. Meteorologists warned that temperatures could approach 40 degrees Celsius in several parts of the country. Emergency services are preparing for a possible rise in heat related medical cases, while fire authorities remain on high alert because of the growing risk of wildfires in forests and dry grasslands.
Although the worst of the heat is now shifting east, countries in Western Europe continue to deal with its impact. France has reported heat related deaths and thousands of emergency medical interventions as hospitals remain under pressure. Several schools have been closed, while outdoor events and tourist activities have been cancelled or scaled back because of the extreme conditions.
Italy also remains under severe heat warnings, with the Health Ministry placing 18 cities under its highest level of alert. Major cities including Rome, Milan, Florence, Venice, Bologna, Turin and Genoa continue to experience dangerously high temperatures. The extreme weather has affected public life, with some cultural and entertainment events cancelled. Italian singer Loredana Bertè was among those forced to cancel a concert after doctors warned that performing in such conditions could pose serious health risks.
The heat has also disrupted transport services across Europe. Germany's national rail operator, Deutsche Bahn, allowed passengers to postpone or cancel long distance journeys without additional charges as railway operators warned that high temperatures could damage tracks, overhead power lines and signalling equipment. National Express also suspended some Rhine Ruhr Express services as a safety measure.
Elsewhere in Europe, roads have buckled under the intense heat, while railway tracks have warped in Sweden. Austrian authorities have also warned that railway infrastructure could be affected if temperatures remain unusually high in the coming days.
Sporting events have not escaped the effects of the weather. Organisers of the Ironman European Championship in Frankfurt shortened both the cycling and running sections of the race to reduce health risks for athletes competing in temperatures expected to exceed 40 degrees Celsius.
Climate scientists say the heatwave is another clear sign of the growing impact of global warming. Researchers from the World Weather Attribution initiative said such an extreme event would have been virtually impossible without human caused climate change. Their analysis found that unusually warm night time temperatures have become about 100 times more likely than they were two decades ago because of rising global temperatures.
Scientists also noted that Europe is warming faster than the global average, making the continent increasingly vulnerable to longer and more intense heatwaves. They warned that rising temperatures are likely to place greater pressure on healthcare systems, agriculture, water supplies and energy infrastructure unless stronger climate adaptation measures are introduced.
Meteorologists say the current weather pattern is being driven by an atmospheric phenomenon known as an Omega block. This occurs when a strong area of high pressure becomes trapped between two low pressure systems, preventing cooler Atlantic air from reaching the continent. As a result, hot air remains over the same regions for several days, causing temperatures to soar well above seasonal averages.
The World Meteorological Organization expects the most intense heat to gradually ease in Western Europe during the coming days. However, the organisation warned that Central Europe and parts of the Balkans will face the next phase of the heatwave before cooler conditions and thunderstorms begin bringing some relief later next week. Until then, authorities across the region continue to urge people to take precautions as Europe experiences one of its most severe June heatwaves on record.
