Klagenfurt, 30 June 2026
GeoSphere Austria and the Austrian Severe Weather Center (UWZ) have issued the red severe weather warning for parts of Carinthia, as severe thunderstorms with hail, gale-force gusts, and heavy rainfall are expected on Monday evening.
Current Warning Levels in Carinthia
The red warning level, the highest category in Austria's severe weather warnings, applies to the districts of Hermagor, Spittal an der Drau, and Villach-Land, according to the UWZ. "Für die Bezirke Sankt Veit an der Glan und Wolfsberg wurde eine markante Wetterwarnung (Stufe Gelb/Orange) ausgegeben. Für die Bezirke Hermagor, Spittal an der Drau und Villach-Land bereits die Warnstufe Rot (akute Unwetterwarnung vor Gewitter und Hagel)", the statement says. Meteorologists expect localized heavy rainfall and stormy wind gusts in the sultry-hot air.
As current data from the Austrian Severe Weather Center (UWZ) and GeoSphere Austria shows, Upper Carinthia and the adjacent mountainous terrain are particularly affected. "Besonders in Oberkärnten sowie im Bergland ist am Montagabend mit teils schweren Unwettern zu rechnen", the meteorologists warn. The central area around Klagenfurt (city/rural district), Villach-Stadt, Feldkirchen, and Völkermarkt is currently still spared according to the latest warnings.
Hail and Thunderstorms Also in Styria
Severe thunderstorms have also been breaking out across other federal states since the afternoon. "Seit dem Nachmittag ziehen über weite Teile Österreichs kräftige Gewitter hinweg", the Severe Weather Center reported. The high lightning activity stretched from Tyrol to Styria. How intense the storms became is evident in images from the municipality of Parschlug in the district of Bruck an der Mur: According to the footage, hail piled up to approximately eight centimeters high. The Severe Weather Center UWZ notes: "Auf den ersten Blick erinnern sie an den vergangenen Winter".
Meteorologist Peter Hinteregger described the development in dramatic terms: "Gewaltige Gewitter-Türme schießen in die Höhe", meteorologist Peter Hinteregger explained. Satellite images continue to show powerful thunderstorm cells across the Alpine region in the evening. The thunderstorms are accompanied by heavy rainfall and hail, significantly increasing the risk of flooding and mudslides.
Warnings of Mudslides and Flooding
Clemens Grohs of Kachelmannwetter warns of "erheblichen Wassermassen in kurzer Zeit". This could cause regional flooding, and mudslides are also possible in the Alpine region. GeoSphere Austria warns that "punktuell kann es zu kleinen Muren, überfluteten Straßen und vollgelaufenen Kellern kommen" could occur. Isolated power outages due to lightning strikes or fallen trees are also possible.
Safety Recommendations from GeoSphere Austria
GeoSphere Austria has also activated a thunderstorm warning and is issuing specific behavioral tips. "Fenster und Türen sowie Dachfenster umgehend schließen" – this appeal is directed by the authority to all residents in the affected districts. "Wanderer im Gebirge sollten rechtzeitig Schutz suchen", it continues. Swimmers are also addressed: "Badegäste sollten bei herannahendem Gewitter sofort die Seen verlassen".
Traffic disruptions are to be expected according to GeoSphere Austria. "Rechne mit Verzögerungen im Straßen- und Bahnverkehr", the weather service warns. Commuters should check their routes before setting off and allow for longer travel times. Fallen trees and flooded roads can significantly disrupt rail and road traffic.
Outlook for Tuesday and Wednesday
On Tuesday, the situation will only calm down temporarily according to the forecast from ubimet. "Vom Alpenhauptkamm aus breiten sich anschließend wieder Schauer aus, am Nachmittag sind stellenweise heftige Gewitter zu erwarten". Maximum temperatures on Tuesday will range between 25 and 38 degrees – the enormous span illustrates how differently the air masses are distributed across Austria. According to the ubimet forecast, the day will begin on the northern side of the Alps with residual clouds before the sun appears intermittently during the morning.
Wednesday will bring turbulent weather once again. "Am Mittwoch ziehen im Westen und Norden bereits in den Morgenstunden Schauer und Gewitter durch", the forecast states. "Im Donauraum und im Osten weht lebhafter West- bis Nordwestwind, im Süden macht sich gegen Abend Nordföhn bemerkbar". Temperatures will reach 20 to 29 degrees on the northern side of the Alps, while 30 to 35 degrees continues to be reached in the south. "Im Süden und Südosten zeigt sich zunächst noch häufig die Sonne. Im weiteren Tagesverlauf steigt dort jedoch ebenfalls die Wahrscheinlichkeit kräftiger Gewitter mit erheblichem Unwetterpotenzial".
The current warning situation makes clear the force of this year's severe weather season in Austria. Only the day before, according to the ubimet forecast, severe thunderstorms had raged in Upper Styria, leaving hail accumulations meters high in the district of Bruck an der Mur. The Severe Weather Center UWZ had already warned on Sunday evening of the combination of heat, high humidity, and rising air – ideal conditions for severe thunderstorms.
For the emergency services in Carinthia, Styria, and Tyrol, the red warning level means increased readiness. Fire departments and rescue services are prepared for possible mudslides, flooding, and lightning-related operations. The public is asked to closely follow the official warnings from the UWZ and GeoSphere Austria and to take the behavioral recommendations seriously.
Numerous images and videos of the hail swarms from Styria and Carinthia are circulating on social media. Many recordings show white hail surfaces covering streets and gardens, indeed reminiscent of a winter landscape. The UWZ comments on the footage with the note: "Auf den ersten Blick erinnern sie an den vergangenen Winter".
For the coming hours, the situation remains tense. The meteorologists at GeoSphere Austria continue to closely monitor the development of the thunderstorm cells. Should the warnings extend to additional districts, such as the central area around Klagenfurt, the authorities will escalate them at short notice. Citizens can stay continuously informed via the official channels of the UWZ and GeoSphere Austria.
The combination of sultry heat, approaching thunderstorm fronts, and orographic effects in the Alps creates, according to the experts, the ideal conditions for supercells and severe hailstorms. Peter Hinteregger and Clemens Grohs emphasize in unison that the coming hours and Tuesday must be approached with particular caution. "Erhebliche Wassermassen in kurzer Zeit" can trigger local flooding that pushes even well-developed drainage systems to their limits.
In conclusion, all involved weather services advise actively monitoring the warnings throughout the night. Those living in an affected district should keep a mobile phone, flashlight, and emergency bag ready as a precaution. With the end of the thunderstorm front late in the evening or during the night leading into Tuesday, the situation is expected to ease – before the next wave follows on Wednesday.
However, it remains unclear how much rain will actually fall and which regions will be hit hardest. The models from ubimet, Kachelmannwetter, and GeoSphere Austria are updated hourly. What is certain: the coming 24 to 48 hours remain a period of heightened vigilance for large parts of Austria, in which every severe weather warning should be taken seriously.
