Communities recovering from recent floods in central and southern Queensland are being warned to prepare for more heavy rainfall this weekend.
The Bureau of Meteorology says the combination of an upper-level low and a surface trough near the Capricornia and Wide Bay coast will bring thunderstorms and moderate to heavy rainfall today and tomorrow.
Almost 120 millimetres of rain has fallen in Mackay since yesterday morning, and senior forecaster Brett Harrison says the rain extended further south overnight.
"We had the highest at Goose Ponds, near Mackay, with 141mm, and Rockhampton [had] 101mm."
He says large totals are expected around the Bundaberg area, with further heavy falls expected in the Darling Downs and Capricornia regions.
"We have seen some heavy rainfall already through the central and Capricorn coastal areas," said.
"We also have had some moderate rainfall through and area south of Toowoomba, as well pushing through to Warwick."
Mt Harrison says Brisbane will escape the worst of the bad weather.
"Brisbane is expecting scattered showers through today and tomorrow [with] moderate falls possible," he said.
"The Darling Downs is seeing more than other areas around the state.
"In terms of what is expected later today, [heavy rainfalls] are going to be around the Capricornia district."
