35 à 38 degrés La prochaine vague de chaleur se poursuit La sécheresse s'intensifie

The water level of Lake Constance has fallen to its lowest point in recorded history, according to recent reports. The lake’s current level is 1.5 meters below historical averages, marking a critical situation for one of Europe's largest freshwater lakes. This decline comes amid prolonged drought conditions affecting much of Switzerland, with temperatures forecasted to rise sharply in the coming weeks. The situation has worsened as a new heatwave is expected to hit the region starting mid-next week, with temperatures predicted to reach up to 38 degrees Celsius in parts of the country. Meteorologist Jan Eitel noted that temperatures could potentially exceed previous records, with some models suggesting that Basel might see temperatures surpassing 39 degrees Celsius. Despite brief periods of rainfall over the weekend, these isolated storms have done little to alleviate the ongoing drought. According to the Swiss Federal Office for the Environment (Bafu), there are currently no signs of sustained, widespread precipitation to ease the dry spell. The drought has affected large areas of western and eastern Central Switzerland, including regions stretching from the Jura Mountains to Basel. These areas have experienced a rainfall deficit of up to 70 percent over the past 30 days. Across the entire country, over a 90-day period, nearly all regions show significant to extreme rainfall deficits. The impact extends beyond the land, with rivers throughout Switzerland carrying unusually low water levels. In several lakes, including Lake Constance, Walen湖, Vierwaldstättersee, Zurichsee, and Lago Maggiore, water levels are far below seasonal norms. According to Eitel, the dry conditions have persisted almost every month since last December, with February being the sole exception when it was overly wet. He expects this pattern to continue until at least mid-August. The federal government anticipates continued below-average rainfall in the upcoming weeks, which will likely exacerbate the drought in many parts of the country. The effects of the drought extend beyond environmental concerns, impacting ecosystems and wildlife. Recent studies indicate that the dry conditions are negatively affecting tick populations and invasive beetle species in Switzerland. The lack of moisture has made it difficult for these organisms to survive, altering local ecological dynamics. Researchers suggest that the prolonged dryness may lead to a temporary reduction in certain pest populations, though long-term consequences remain uncertain. Local authorities and environmental agencies are monitoring the situation closely, with officials expressing concern over the potential impacts on agriculture, tourism, and water supply systems. Water management strategies are under review, particularly in regions reliant on Lake Constance for drinking water and irrigation. Some communities have already begun implementing water conservation measures, while others are exploring alternative sources to mitigate the risk of shortages. As the heatwave approaches, residents and officials are bracing for further challenges. Emergency services are preparing for increased demand due to higher temperatures and potential health risks associated with heat exposure. Public advisories urge caution during outdoor activities and emphasize the importance of staying hydrated. Meanwhile, scientists continue to analyze weather patterns and climate trends to better understand the frequency and intensity of such extreme conditions. The situation underscores the growing vulnerability of Switzerland’s environment to climate change, with experts warning that similar events may become more common in the future. As the country faces this unprecedented challenge, the focus remains on adapting to the changing climate while safeguarding natural resources for future generations.
