Supercell storms are the most serious thunderstorm events Australians experience, and they are dangerous for a number of reasons.
They last for a relatively long time and can maintain intense power for many hours.
They also have what forecasters call highly organised circulation – a continuous, strong updraught which means supercell storms can exert control over the surrounding atmosphere.
Thursday’s supercell event was proof of how powerful and destructive they can be, producing wind gusts of 140km/h, which is equivalent to a category 2 cyclone.
