More heavy rain and flash flooding is expected to hit Queensland's Gulf Country on Monday with falls up to 250mm over the next day.
A severe weather warning stretches from the Gulf Country across the tropical coast and down to the Burdekin region.
Between Tully and Ayr, including flood-hit regions like Ingham, rainfall is expected to ramp up until Wednesday.
"This rain is falling onto saturated land, particularly along the north-east coast, as well as flash flooding, we may still see further river rises," meteorologist Miriam Bradbury said.
Multiple flood warnings are in place for major rivers across northern Queensland including the Herbert River at Ingham which reached beyond the 1967 disaster level last week.
It comes after a wet weekend with rainfall totals of 143mm at Rollingstone on the tropical coast, 104mm at Kowanyama in the state's northwest, and 88mm at Paradise Lagoon on Sunday.
There were more than 60 requests for State Emergency Service assistance in flood-affected regions in the past 24 hours, including tarping requests due to leaking ceilings, sandbagging requests due to groundwater entering homes, and resupply.
The persistent wet weather has hit regions already impacted by flooding, marking more than a week since some towns like Ingham were submerged.
Around 1900 residents remain without power across northern Queensland with Ergon Energy hoping to restore most services on Monday.
