Heavy rainfall leads to flash flooding in parts of south-east Queensland, with more wet weather to come

A rainband is falling over an already-sodden Queensland, with flash flooding reported across parts of the south-east.
Pieter Claassen from the Bureau of Meteorology (BOM) said the region is in for another wet week, with rainfall predicted to peak either Tuesday or Wednesday.
The senior meteorologist said the region is expected to see between 10 and 40 millimetres on both days, kicking off the beginning of "a really wet few days".
Locally heavy falls have already resulted in flash flooding across parts of the Brisbane CBD and Milton, south-west at Warwick, Luscombe near the Gold Coast, Washpool and Mutdapilly in the Scenic Rim, plus Miles and Chinchilla on the Western Downs, according to QLD Traffic.

Mr Claassen said severe thunderstorms could form across the Darling Downs, Maranoa and Warrego districts, but scattered showers were more likely.
"Some isolated rainfall over 50mm [are] possible in the south-east region," he said.
"Yesterday, parts of the Darling Downs saw up to 81mm [in] Warwick, with all of that rainfall falling in just one hour.
"That's indicative of some of the locally heavy rainfall that is a risk across parts of the south-east, particularly the interior over the next day or so."

The BOM said south-easterly gusts were combining with an upper trough approaching from the west to "form this rainband across south-east Queensland".
"It's a turnaround from the severe thunderstorms we were seeing … the atmosphere is very saturated, so very cloudy conditions [are predicted]," Mr Claassen said.
Risk of riverine and flash flooding
On early Tuesday, Western Downs Regional Council issued a "prepare to leave" warning for residents in low-lying areas of Jandowae, a rural town north of Dalby.
The watch and act alert said the local dam was "approaching the flood level of 0.5m" with "further water level rises expected".

Mr Claassen said he couldn't rule out the risk of riverine and flash flooding "anywhere in south-east Queensland" given the already-sodden ground in some areas.
"Obviously, catchments are quite saturated [currently], so rainfall does bring with it the risk of elevated river levels," he said.
"We're not likely to see flood levels exceeded at our forecast locations … but that's something we're keeping a very close eye on."

On Thursday, the Central Queensland coast could see locally heavy rain and widespread moderate falls.
"The other risk area that we're looking at [includes] Mackay, up to Hamilton Island, even down to Yeppoon," Mr Claassen said.
"Remaining very wet in those parts right through the rest of the week, but the risk of that heavy rainfall should start to ease from the weekend."
Cooler temps in the south, heat further north
While rainfall totals in the south-east should peak on Tuesday or Wednesday, cloudy conditions and "usual" cooler temperatures will continue.
"We're seeing temperatures up to seven degrees below average by Wednesday, and really throughout the week temperatures are forecast to be at least a few degrees below average," Mr Claassen said.
"Quite a cool week ahead as well — 25 degrees is the top today, then down as low as 22 degrees by tomorrow.
"We do start to see some of that cloud clear, particularly from late in the weekend, and that will help those temperatures warm up a little [then] approaching more average temperatures."

Further north, tropical regions above Gladstone are expected to see the wet weather too, with rainfall on the Cairns coast peaking around Friday.
A heatwave warning is also in place around the Peninsula and Gulf Country regions, which currently extends to Thursday and includes maximum daytime forecasts of temperatures in the mid-30s to low-40s.
