What would you classify as a "severe" storm?

A "severe" storm - what does it mean exactly? "This is always a very arbitrary choice, so what one person might consider βsevereβ, another would only call βmarginalβ. It also depends on where you are, because if you are walking in the mountains, even one flash of lightning can be extremely dangerous. If you are sitting inside your warm, cosy house, it is not so threatening", explains TomΓ‘Ε‘ PΓΊΔik, a Researcher and Senior Trainer at ESSL (European Severe Storms Laboratory) in the interview on the EUMETSAT blog.
TomΓ‘Ε‘ also gives us the criteria a severe thunderstorm must meet to be classified as a "severe" in the ESSL's severe weather reports. To classify, it has to meet at least one of the following:
- The storm produces some wind-gust damage (if the wind exceeds 90 km per hour)
- There are hailstones larger than 2cm in diameter
- There is a tornado present
- The storm produces flash flooding
