This change in direction is characteristic of a supercell thunderstorm, which is a powerful rotating storm that can cause heavy rain, huge hail and sometimes, tornadoes.
Soon after the storm, photos and videos starting to emerge on social media showing what looked be a tornado or waterspout near the Port of Brisbane just after 10am.
Shortly after midday AEST, the Bureau of Meteorology confirmed that a tornado had indeed tounched down in Brisbane on Friday morning.
