Slovenia is preparing for significant weather changes on the evening of September 5, 2025, as a cold front moves in from the north. The Slovenian Environment Agency (ARSO) has issued an orange thunderstorm warning for its eastern regions, signaling a heightened risk of severe weather conditions.
The anticipated storms are expected to form over southern Austria before moving into Slovenia, with the northeastern parts of the country most likely to experience intense thunderstorms. These storms could bring strong wind gusts and hail. Precipitation is forecast to move southeastward and gradually decrease by the early morning hours of September 6. Following the storm system's passage, northerly winds are predicted to become dominant across Slovenia, with a possibility of weak bora winds along the coast.
Authorities are advising residents and visitors in the affected areas to stay informed through official updates and to take necessary safety precautions. This warning comes after a wave of extreme weather impacted Central and Southern European countries, including Slovenia, in early July 2025. That event brought hurricane-force winds, torrential rain, and large hail, causing considerable damage. In Slovenia, towns such as Ptuj, Maribor, and Murska Sobota reported damaged rooftops, fallen trees, and power outages, with ARSO recording wind gusts exceeding 90 km/h in multiple locations.
The recent weather events underscore the importance of heeding official warnings and preparing for potential disruptions. Slovenians generally demonstrate a high level of awareness and preparedness for disasters, with a recent survey indicating that citizens feel most vulnerable to extreme weather events. This proactive stance is crucial when facing the unpredictable nature of severe storms, which can lead to flash floods, landslides, and disruptions to transportation networks.
