Being out in the nature while a thunderstorm is imminent can be very dangerous. While some people or companies rely on lightning radars and detectors for their work, some might feel better and more safe if they know about upcoming thunderstorms and the risk of lightnings. Nevertheless, detection systems are most of the times very expensive and not really affordable for an ordinary person. Luckily, those detection devices are often used to, obviously, detect the thunderstorms and lightnings, but then people are actually willing to provide the data online.
