Queensland is staring down another week of storms, with the central coast predicted to cop a battering of heavy rain which could flood already drenched towns.

A deepening coastal trough is forming off the central coast of the Sunshine State with rain forecast to begin on Tuesday and worsen through to Thursday.

Some models predict a low-pressure system could also form, increasing the risk of heavy rain and flooding to sodden coastal towns.

More than 200 millimetres of rain is predicted to hit between Mackay and Rockhampton this week while inland towns around Roma will get more than 100 millimetres.

“There is potential for heavy rain and flooding in the state’s central coastal districts around Thursday,” Weatherzone’s Ben Domensino said.

The Bureau of Meteorology says there will be widespread rain and sporadic “hit and miss” thunderstorms on Tuesday as a rain band extends from the south-east through to the Gulf Country.

“Storms may be severe, with heavy rainfall about the Central Highlands extending into the Darling Downs Granite Belt, and also about the Maranoa and south east coast,” meteorologist Sarah Scully said.

People in those areas are being urged to heed warnings after weeks of wet weather that’s already left the ground saturated.

North-eastern NSW will also experience widespread showers and isolated thunderstorms with potentially heavy rainfall.

The high-risk weather season in Queensland has begun with regular storms hitting the south-east.

One storm last Wednesday drenched Brisbane with more than 50 millimetres of rain in an hour.

Another brought winds of more than 100km/h to the central-western NSW town of Carinda on Sunday, smashing roofs from buildings and bringing down power poles.

The high-risk season also brings the potential for cyclones to form from December. The weather bureau forecasts that at least one will make landfall on the Queensland coast.
