Slovenia is anticipating 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 storm warning for the eastern parts of the country, indicating a considerable risk of severe weather.
The storms are expected to originate from southern Austria and move into Slovenia, with the northeastern regions most likely to experience intense thunderstorms. These could be accompanied by strong wind gusts and hail. The anticipated rainfall is forecast to move southeastward and subside by the early morning of September 6. Following the passage of the front, northerly winds are expected to prevail across the nation, with a possibility of weak bora winds along the coast.
Authorities are advising residents and visitors in the predicted impact zones to monitor official updates and implement necessary safety measures. Severe weather, including thunderstorms, heavy downpours, and hail, has been a recurring issue in Slovenia, as seen in early June 2025 when similar warnings were issued for central and eastern regions, causing travel and business disruptions.
Historically, Slovenia has also experienced flash floods due to heavy rainfall, such as the events in August 2023, which led to evacuations and infrastructure damage, highlighting the country's vulnerability to extreme weather phenomena. ARSO had previously issued red warnings for northeastern, northwestern, and central Slovenia due to prolonged downpours, underscoring the importance of vigilance regarding changing weather patterns.
The public is urged to remain alert and follow the latest weather information from official sources to ensure personal and family safety. Preparedness is key in navigating these dynamic weather conditions.
