ROME, June 29 – A relentless heatwave continued to grip large parts of southern and central Europe on Monday, pushing temperatures to dangerous levels across Italy and the Balkans while raising fresh concerns over wildfires, public health, and critical infrastructure. At the same time, millions of Americans were preparing for an intense stretch of hot weather ahead of the Independence Day holiday, with weather officials warning that prolonged exposure could become life threatening.
The extreme weather has affected daily routines, strained emergency services, and heightened fears that climate-related disasters may become increasingly frequent. Authorities in several countries have urged residents to stay indoors during the hottest hours of the day, remain hydrated, and pay special attention to older adults, children, and people with existing medical conditions.
Europe Faces Escalating Heat and Wildfire Threat
Italy remained one of the countries most affected by the ongoing heatwave. The country’s civil protection authorities placed 22 cities under the highest level of heat alert, covering locations from Bolzano in the north to Palermo in Sicily. Health officials advised residents and tourists to limit outdoor activity during peak afternoon hours as temperatures continued to climb well above seasonal averages.
The intense conditions were also evident in Rome, where thousands of worshippers gathered in Vatican City for the Feast of Saints Peter and Paul. Many pilgrims relied on umbrellas for shade and handheld fans to cope with the scorching weather while Pope Leo delivered the traditional Angelus address from the Vatican balcony.
Across the Adriatic Sea, Croatia faced growing wildfire concerns as authorities issued the highest weather warning for several regions, including Zagreb, Split, and Dubrovnik. Firefighters, supported by water dropping aircraft, worked to contain a wildfire that spread through pine forests on the island of Vis, a popular tourist destination. Emergency crews continued efforts to prevent flames from reaching nearby communities and environmentally sensitive areas.
Neighboring Serbia also remained under intense heat. According to the country’s State Hydrometeorological Service, temperatures were forecast to reach around 39 degrees Celsius, approximately 102 degrees Fahrenheit, creating hazardous conditions across much of the country.
Further south, firefighters in Albania managed to contain a wildfire near the village of Klos after flames burned through extensive areas of shrubs and olive groves during the weekend. Although the immediate danger had eased, officials warned that continued high temperatures and dry conditions could quickly trigger new outbreaks.
Meteorologists noted that the heatwave, which began around June 20, has already rewritten several early summer temperature records across Europe. Beyond discomfort, the prolonged heat has disrupted electricity production, placed heavy pressure on healthcare systems, and contributed to damage affecting roads, railways, and other infrastructure.
Health Concerns Grow as Climate Experts Warn of Long Term Risks
Public health authorities across Europe continue to monitor the human impact of the prolonged heat. France has reported approximately 1,000 excess deaths associated with the recent period of exceptionally high temperatures. According to the French public health agency, older adults account for the majority of heat related fatalities, and officials believe the final number could increase as additional cases are reviewed.
French media organizations also reported that funeral homes in Paris and surrounding areas experienced significant pressure because of the unusually high number of deaths during the heatwave.
Climate researchers have also linked the severity of this event to the long term warming of the planet. Scientists studying the phenomenon said that nighttime temperatures recorded during the latest heatwave would have been extremely unlikely without the influence of human driven climate change. They estimated that such unusually warm nights are now roughly one hundred times more likely than they were only a few decades ago.
Italian Air Force meteorologist Daniele Mocio explained that exceptionally warm conditions were expected to continue across central and eastern Europe for several more days. He said temperatures in some locations were running between 8 and 10 degrees Celsius above the seasonal average. Although western Europe has seen a temporary drop in temperatures, forecasters believe the relief will likely be brief.
Luca Mercalli, president of Italy’s Meteorological Society, also warned that another surge of extreme heat could arrive during the first week of July. He said weather models indicate that countries including France, Spain, Germany, Italy, Switzerland, and parts of Britain may once again experience unusually high temperatures.
Mercalli noted that while rising temperatures significantly increase the likelihood of forest fires, localized thunderstorms have also developed in some regions. However, these storms have produced uneven rainfall, providing relief to only limited areas while leaving others vulnerable to continued drought and wildfire danger.
United States Prepares for Dangerous Heat Before Independence Day
Extreme temperatures are not limited to Europe. In the United States, the National Weather Service has warned that a large section of the central and eastern states will experience dangerous heat during the days leading up to the 4th of July celebrations.
Forecasts indicate daytime temperatures will reach the upper 90s and lower 100s degrees Fahrenheit across many communities. Weather officials stressed that the combination of intense daytime heat and limited cooling overnight will increase the risk of heat exhaustion and heatstroke, particularly for older adults, young children, outdoor workers, and people without reliable air conditioning.
The National Weather Service encouraged residents to drink plenty of water, reduce strenuous outdoor activities during the hottest part of the day, and regularly check on family members, neighbors, and others who may be especially vulnerable to heat related illness.
Meanwhile, several recent tragedies have underscored the dangers associated with extreme temperatures. Police in Cyprus confirmed that two boys from Bulgaria, aged eight and ten, were found dead inside a parked vehicle on Sunday afternoon. Authorities are continuing to investigate the circumstances surrounding the incident. Although temperatures on the island were around 38 degrees Celsius, officials noted that such conditions are considered typical for this time of year and were not formally classified as a heatwave.
In Poland, organizers of the Poland Bike Marathon reported that two cyclists, aged 30 and 71, died while participating in a cycling event near Warsaw during the weekend. Authorities are examining the incidents as part of routine investigations while medical experts continue to remind the public about the serious health risks associated with strenuous physical activity during periods of extreme heat.
As Europe and North America face another week of unusually high temperatures, governments, emergency responders, and health agencies continue urging the public to follow official safety guidance. Scientists warn that prolonged heatwaves are becoming more frequent and more intense, making preparation, public awareness, and climate resilience increasingly important in protecting lives and communities.
