Queensland is bracing for a possible cyclone later this week, with heavy rains - and potential flash flooding - forecast for the state.

Far North Queenslanders warned to expect gale-force winds, flash flooding and higher-than-normal tides in the coming days.

One thing gaining traction in scientific circles is the consensus that warmer oceans caused by climate change are giving storms extra energy.

Parts of Queensland are drenched after more than 200 millimetres of rain fell in less than 24 hours — and there is more rain and potentially a cyclone on the way.
