Flooding is among Australia's most deadly natural disasters. So, what causes floods and how will you know if there's one on the way?
Flash flooding is a significant threat across Australia. It can cause roads to become rivers, washing away cars and people. And it's not just people living near rivers who are at risk; flash floods are particularly dangerous because they can affect areas away from watercourses and happen with little or no warning. So, what causes them and how can you stay safe?
Huge downpours of rain brought devastating floods to parts of northern Queensland and the Northern Territory early in 2019. This water made a slow journey south, filling the Georgina, Diamantina and Warburton rivers and flooding desert towns as it travelled. A second rain system in late March brought more water, extending across vast flood plains and eventually flowing into Kati Thanda-Lake Eyre many weeks after it fell, bringing life and colour to this dry country. So how and why did the water end up in Australia's largest lake?
