UP to 60 homes on the Gold Coast are expected to be swamped by rising floodwaters within the next three hours.
Evacuations have been ordered on the northern Gold Coast as overflow from the Albert and Logan Rivers approach the region.
Police fear floodwaters could hit residents near the northern suburbs of Stapylton and Jacobs Well around 2pm AEST and have begun door knocking residents, asking them to evacuate.
Residents are also being warned that if they don't evacuate they could risk being trapped for several days.
The evacuation order affects the following streets: Quinns Hill Road East, Rossmans Road, Wohlsen Road, Zipfs Road, Bruckner Road, Cooks Road, Rotary Park Road.
Authorities are also assessing how wide the flood impact may be. Residents in these streets should also consider evacuating: Cowley Road, Finglas Road, Goldmine Road, Creek Street, Minka Lane and Halfway Drive.
Police Commissioner Ian Stewart earlier residents in low-lying areas in Logan and the northern Gold Coast should consider leaving for higher ground.
"There are urgent alerts and we'd ask the community to take them seriously," he said.
"I would suggest many thousands of people would live in that area."
Commissioner Stewart said people in those areas were required to move to safety.
