Life-threatening flash flooding and up to 300 millimetres of rain are possible in parts of northern Queensland as ex-Tropical Cyclone Imogen tracks across the region.
The Bureau of Meteorology has advised Imogen was located 60 kilometres east-northeast of Georgetown at 4am AEST and is forecast to track slowly in an east-southeast direction.
A trough extends eastwards through the North Tropical Coast and Tablelands to the south of Innisfail and is forecast to slowly move south.
Widespread heavy rainfall could affect areas between Tully and Townsville in the morning before it extends to about Ayr during the rest of Tuesday.
Several flood warnings are current throughout the area for locations including Townsville, Ingham, Cardwell, Ayr, Giru, Atherton, Ravenshoe, Greenvale and Charters Towers.
Tropical Cyclone Imogen crossed the coast north of Karumba shortly before 11pm on Sunday before slowly weakening to a tropical low on Monday.
About 1400 houses were left without power, but there were no reports of injuries, Police Commissioner Katarina Carroll said.
"It would appear at this stage there is no massive damage either, but there is a lot of water," she told reporters on Monday.
The system dumped 262mm of rain in Normanton, with 186mm of that falling in six hours up until 3am on Monday, the Bureau of Meteorology's Pieter Claassen told AAP.
