The full extent of south-east Queensland’s flooding damage may soon be revealed with rain finally set to ease.

Thousands lost power, more than 20 schools were closed, roads were cut and 39 swiftwater rescues were completed as severe weather lashed the area on Tuesday.

Some of the worst hit were north of Brisbane in the Moreton Bay area and the Sunshine Coast, while Lockyer Valley further west was also inundated.

Queensland Premier Steven Miles said authorities had tried to assess the damage on Tuesday but crews kept getting called away for swiftwater rescues.

Dozens of homes are believed to be damaged in Bray Park alone.

There were concerns on Tuesday night for other people in the Moreton Bay area as well as the Sunshine Coast, particularly in the Caboolture River’s low-lying catchment with rain continuing.

Evacuation centres have been set up in the Moreton Bay region where the SES responded to 100 calls for help.

A severe weather warning was current from north of Brisbane on the Sunshine Coast up to Bundaberg, with six-hourly rainfall totals between 80-150 millimetres possible through to Wednesday morning.

Severe thunderstorms were set to extend rainfall totals up to 250 millimetres in some areas, leading to more flooding.

Miles was to outline financial assistance to be made available for flood victims on Wednesday.

“I want all Queenslanders to know wherever they are affected by these floods we will be there to make sure that they are supported through the clean-up and getting back on their feet,” he told Seven Network.

Mother Nature may also provide some flood relief to the south-east on Wednesday, with rain expected to drift north through the Wide Bay and Burnett areas.

By Wednesday night showers and storms are forecast for the tropical north but the southeast is set to be dry.

“We have dry weather on the way from Wednesday onwards and that should last us through to the end of the weekend,” a bureau spokesman said.

However heavy rain causing flooding is still lingering in the Mount Isa area in the state’s north-west due to the remnants of ex-Tropical Cyclone Kirrily, days after it crossed the coast.
