Monster trough brings heavy rain to south-east Queensland

A slow-moving system is enveloping Queensland’s south-east, bringing an excess of rain to the region.

Already one carpark at Garden City Shopping Centre in Brisbane has been flooded, while the rains have left some roads in Archerfield submerged.

An unlucky Gold Coast motorist attempted to ford floodwaters, only to have their car overturned.

It was the Sunshine Coast however that received the heaviest falls, with more than 100mm falling at Sippy Downs in a few hours.

Mount Nebo recorded 90mm while Inala, south of Brisbane, received 69mm.

Mount Mee received 65mm in just one hour, compared to 62mm in an area west of Tewantin.

Flooding was reported both in the Sunshine Coast and in Rockhampton and Bundaberg.

The rain was the result of a trough delivered flooding rains throughout southern Australia.

“It's basically the top extension of what we call the upper-level trough which caused all that damage and widespread rainfall in Victoria and New South Wales,” Bureau of Meteorology forecaster Diana Eadie told 9NEWS.

“For Brisbane in particular we're expecting slightly cooler than average temperatures but beautiful clear skies (going forward).”

Earlier today, the Bureau of Meteorology issued severe thunderstorm warnings for a large swath stretching from Coolangatta to the Sunshine Coast.

Heavy rain posed a flash flooding risk in parts of Brisbane City, the Sunshine Coast, Gold Coast, Logan, Moreton Bay and Redland City.

Beenleigh, Logan City, Cleveland, Redcliffe and Caloundra were all listed as being within the area of immediate threat, while surrounding areas like Ipswich, Brisbane CBD, Caboolture, Maroochydore, Noosa Heads and

Gympie were placed on alert.

Damaging winds and large hailstones were also forecast for the south-east coast and parts of the Central Highlands, Coalfields, Wide Bay and Burnett regions.

Residents in affected areas have been advised to avoid floodwaters, fallen trees and powerlines, while seeking shelter and steering clear of using landlines during thunderstorms.
