Austria's national weather agency issues warnings for potentially dangerous weather on a scale from yellow to red. But what does the weather alert system mean, and what should you do if there's a warning?


As Austria gets more affected by global warming, the frequency of extreme weather increases. 

Austria has an advanced system of warnings led by the country's Meteorological Service GeoSphere Austria. "Our regular verification shows a high level of accuracy in the warnings. This is very important for the acceptance and behaviour of the population," said Dr Andreas Schaffhauser, Scientific Director General of GeoSphere Austria. 

He added: "The better and more comprehensible warnings of major weather events are, the more seriously they are taken and the greater the chance that people will respond to them."

Austria follows a traditional weather warning system consisting of three colours: yellow, orange, and red.

A yellow warning means caution (Vorsicht!). It means that caution in the current weather scenario is urged, but only isolated weather-connected endangerment and/or damages are anticipated.

An orange warning means attention (Achtung!!), as the current weather scenario can lead to endangerment, disturbances in everyday life and damages. People should pay close heed to the ongoing weather forecasts.

Finally, a red warning means danger (Gefahr!!!). In this case, the current weather scenario is expected to lead to extensive endangerment, disturbances of everyday life and/or considerable damage. People should pay close heed to the ongoing weather forecasts and comply with the instructions of the Civil Defence. 

Each warning is usually issued for one or more weather conditions such as wind, rain, snow, black ice, thunderstorm, heat stress and cold stress.

Avalanche risk

The European Union has an online tool to check the dangers of avalanches, the European Avalanche Warning Services. You can zoom in and click on the province where you are travelling to get more information, or just check using the links below:

There are no high mountains with a risk of avalanches in large parts of Upper Austria, Lower Austria, and the entire provinces of Burgenland and Vienna.

There are five danger levels in Austria: 1 – low (green), 2 – moderate (yellow), 3 – considerable (orange), 4 – high (red) and 5 – very high (red and black). These colours are also used to mark avalanche risk in loco, so if you see an avalanche sign in orange, for example, it indicates a considerable risk in that area.

Danger level 5 is rarely forecasted, while danger level 3 is forecasted for around 30 percent of the winter season. Approximately 50 percent of avalanche fatalities happen while the level is “considerable”.


Warning systems

In case of more severe or sudden alerts, Austria also has emergency systems in place. For example, the country's civil defence alarm has nationwide warning siren systems.

Different sounds mean different things: 

  • TESTING (15 seconds continuous tone): A quick continuous tone to test whether sirens work correctly.

What to do: don’t panic; this is only a test. You can check ORF on radio, TV or online to confirm this.

  • WARNING (3 minutes continuous tone): A constant continuous tone with a length of 3 minutes means “warning”. This signal is triggered when the population is warned of approaching danger.

What to do: Switch on radio or TV on public broadcaster ORF, or check and follow the rules of conduct.

  • ALARM (1 minute rising and falling wailing tone): An ascending and descending wailing tone of at least 1 minute duration means “alarm” and alerts that the danger is imminent.


What to do: Switch on radio or TV on public broadcaster ORF, or check and follow the rules of conduct. Look for protective areas or rooms.

  • ALL CLEAR (1-minute continuous tone): A constant continuous tone of 1 minute (only after the alarm signal) means “all clear”, i.e. end of danger.

What to do: Continue to pay attention to the announcements on the radio, TV or ORF online, as there may be certain temporary restrictions.

The Ministry of the Interior's official smartphone app, KATWARN, is a system that displays information and warnings from various authorities on a location-based or topic related to smartphones.

The app complements the existing warning options such as sirens, loudspeakers and media broadcasts. The advantage is that it can immediately warn people of any significant events, informing them of the danger and, just as important, giving immediate information on how to behave.

If you live in Vienna or go there often, the official Stadt Wien app is very useful. It brings essential news and pushes notifications on traffic disruptions near you, weather alerts or civil emergencies.
