Southeast Queensland smashed by a month's worth of rain in 24 hours

Southeast Queensland has copped a drenching in the last day with more than 70mm of rain falling overnight and more expected this evening.

The region is set to be hit with a further month's worth of rain in coming days with a chance of thunderstorms in Brisbane and on the Gold Coast.

"It was a very wet night last night," Dean Narramore from the Bureau of Meteorology told Today.

"We saw 25-45mm pretty much from the Sunshine Coast all the way to the NSW border and well inland towards Toowoomba and out into the Darling Downs as well."

Another round of rain is expected to move in from the west and some areas could see up to 50mm of rainfall with storms, Mr Narramore said.

Mr Narramore said the bureau was not expecting any major flooding as a result of the rain given the weather had been fairly dry over the last few months.

At Evans Head, 85.2mm of rain was recorded today, marking the wettest October day for the region in 11 years.

In Brisbane, 40mm has been recorded since yesterday, and 79mm at Mt Glorious.

On the Sunshine Coast there has been 67mm and in the Upper Springbrook 62mm.

A severe thunderstorm warning has since been issued for heavy rain and large hail in the state's south-east.

Rain and showers will mostly ease on Wednesday, but more showers and storms will return on Thursday, with further severe storms possible.

Queensland is heading towards cyclone season, which begins in November and lasts through to April.

"We normally average 11 cyclones in our area of responsibility which is a huge part of ocean from west to east across Australia," Mr Narramore said.

"There's always a risk every year particularly towards November through to April where could see a crossing cyclone on the Queensland coast.

"It's good to be prepared in the coming months."
