Strength was unpredictable, warning time short

Fire brigade deployments and record rain have already been reported in the afternoon in Vorarlberg – more information at But as the new extreme weather threatens, the shock from Thursday’s storm is still profound. Several experts from the Central Institute of Meteorology and Geodynamics (ZAMG) said on Friday that their strength was hardly predictable. According to ZAMG, the storm line developed very rapidly and more violently than predicted by the forecast models and also had a slightly more eastern focus.

The storm was unpredictable in Carinthia. As Christian Stefan, head of the ZAMG in Klagenfurt, said in an interview with the APA, such a meteorological phenomenon is extremely rare there: in a few minutes there was a shift from a light wind to just over 100 km / h. In the Carinthian Lavant Valley, for example, the storm raged for only ten minutes. It is possible that the strength of the hurricane was also achieved in places without measuring points.

Thunderstorm warning was given, an exact forecast or the specific storm pattern was therefore not recorded well. To some extent, thunderstorms are unpredictable, says Stefan. The fact that the potential for severe thunderstorms existed was already relatively well estimated: “But it is difficult to estimate where they will then rise and fall.” – More information on

20 minutes notice

According to the Styrian civil protection, there was only about 20 minutes’ notice, too little to warn the population by radio, chief Harald Eitner told the “Kleine Zeitung”. The state alert center itself was surprised by the intensity of the storm because it could hardly have been predicted.

According to ZAMG experts, the storm front pushed hot air in front of it. The storm itself was harmless, but the storm was even stronger. However, the models did not foresee this. “You can’t see the wind on the satellite image,” Eitner says.

Shock and damage after the storm

The day after the severe thunderstorms with five deaths in Carinthia and Lower Austria, things are sorting themselves out. In western Austria, forecasters expect heavy rains, landslides and floods.

The storm lasted perhaps ten minutes at around 3:30 pm and the blast that cut down the trees only took seconds. According to the rescue service in the water, such an elementary event has never occurred in the area: the lifeguards who wanted to warn the swimmers of the sudden storm were swept away and waves 50 centimeters high were recorded. Trees have fallen on visitors to the bathroom. The area could not be cleared at that time. The area was cordoned off by the Public Prosecutor’s Office. An expert has taken the job, he should check, among other things, whether the trees have been cut correctly.

The storm front also left a picture of devastation in many regions of Styria. Most counties reported damage, some severe, from falling trees on roads, buildings and vehicles. Numerous roofs of houses were covered. In the Gösting district of Graz, a tree crashed into the windshield of a moving car. The three occupants remained unharmed. The same applies to the occupants of a bus in St. Peter Hauptstrasse, on which parts of a roof had fallen.

extreme weather

Although individual extreme events cannot be traced directly to a specific cause, according to the Intergovernmental Panel on Climate Change it is clear that extreme weather events such as floods, storms and heat are becoming more frequent and more intense due to the climate crisis. This means: rainfall and storms are getting heavier, heat waves are getting hotter, and drought is getting drier.

Several hikers had to be rescued from the Styrian mountains – as helicopter rescue was not possible, the mountain rescue team came on foot. On Thursday in Gaal, in the Styrian district of Murtal, about 60 people, including small children, had to be taken out of the danger zones, some by helicopters. Access to Ingersee was blocked after the storm. No one was injured, more information on
