Several areas of south east Queensland copped a month's worth of rain during the very wet weekend, while Brisbane recorded its wettest February day in 46 years with 218 millimetres falling on Sunday.
The Gold Coast recorded around 150mm, the Hinterland was drenched with more than 300mm, while Townsville collected 232mm on Saturday alone, almost the town's monthly average.
Bureau of Meteorology forecaster Lachlan Stoney said more thunderstorms are expected to hit most of the state on Monday afternoon, thanks to a southerly change pushing up the coast.
"That's likely to kick off more thunderstorms that could be quite gusty at times. Once that change pushes through it'll be quite cloudy and a bit drizzly, but we'll return to some more stable conditions, just a few showers pushing in from the coast, then mostly sunny conditions throughout the week," he said.
It's the same deal down south, with Sydney likely to have its heaviest rainfall since winter tonight, between 25mm and 50mm expected to fall by tomorrow morning.
