HUGE swathes of the Queensland coastline are expected to be hit by heavy rains, gale-force winds and flash flooding from Sunday afternoon.
Emergency Management Queensland has warned those living from Bowen to the New South Wales border to prepare for the weather onslaught.
Thunderstorms are expected to develop on Saturday afternoon in Central Queensland, including the highlands, with those spreading to include south-east Queensland by the end of the weekend.
Those in these areas should begin preparing for the flash flooding and damaging winds expected to accompany the storms.
Weatherzone meteorologist Josh Fisher said wind gusts of between 90kmh and 100mh were being predicted.
"That has the potential to bring down trees and cause minor structural damage, but it would be mostly be trees and powerlines," he said.
The Bureau of Meteorology warned the weather system could pause over Bundaberg, a region still reeling from the flood devastation delivered by cyclone Oswald earlier in the year.
EMQ assistant director-general Bruce Grady warned Queenslanders needed to be ready.
He said home emergency kits needed to be checked, easily accessible and stocked with essentials.
"If you are located in an area which could potentially be impacted by localised flooding, move vehicles, outdoor equipment, indoor items, garbage, chemicals and poisons to higher locations," Mr Grady said.
"Also be alert to the dangers associated with falling trees as a result of the anticipated high wind gusts.
"People should stay informed by tuning into their local radio and monitoring the BoM website for the latest information."
Mr Grady said Queenslanders must not consider crossing roads or waterways hit by floodwaters.
"Under no circumstance should people enter flooded creeks or causeways by road or on foot and if you come across rising floodwaters, turn around and seek an alternative route," he said.
"Parents, please also discourage your children from playing or swimming in flooded creeks and drains.
Floodwaters are deadly and the dangers are lurking beneath the surface."
