Northern Queensland is in the firing line for rainfall totals exceeding triple digits through to the end of the week just a month after floodwaters subsided.
The Bureau of Meteorology has forecasted rain extending across the tropical coast, inland to central Queensland and south towards Mackay.
Townsville and the coastal range will likely see the heaviest falls on Tuesday through to Thursday.
"It's likely that some locations, particularly about the North Tropical Coast, will receive triple digit rainfall totals day after day," meteorologist Miriam Bradbury said.
"This will result in river rises and potentially significant flooding."
The heavy rainfall is expected to ease later in the week but river levels may remain swollen, Ms Bradbury warned.
Multiple flood warnings are already in place for the Tully and Bohle Rivers, and more catchments are expected to be added in the next few days.
It follows the region being drenched by heavy rain over the last day around Tully, Innisfail and Townsville.
Some of the highest rainfall totals include 248mm at Paradise Lagoon with 75mm of that within an hour on Tuesday morning.
There was 235mm at Paluma, 226mm near Innisfail and 127mm at flood-weary Ingham which was one of the worst affected areas in the February disaster
Floodwaters claimed the lives of two women in Ingham after the nearby Herbert River, in the Hinchinbrook Shire, broke a record level set back in 1967.
The remote town saw the army step in to help rebuild a bridge crossing after it was completely isolated by floodwaters.
February 2025 was the wettest month in history for some north Queensland towns with Paluma near Townsville recording more than two metres of rain - double what Sydney receives in a year.
At one stage, 70 schools were inundated and more than 30,000 homes lost power.
As of last week, insurers had received more than 7600 claims estimated to cost more than $164 million across Townsville, Ingham, Innisfail, Mission Beach and Cardwell.
