Communities in the far north of Australia's Queensland state are bracing for torrential rain as a tropical low weather system in the Gulf of Carpentaria moves east.
A cyclone warning has been issued for coastal communities from Karumba to Cape York, including Mornington Island.
The low has gusts of up 85 kilometres per hour and is about 115 kilometres north of Mornington Island, moving east at 23kph.
Forecasters say the system will dump torrential rain across the state's far north as it moves over land.
Senior forecaster Brett Harrison said the system was likely to become a cyclone on Monday or Tuesday.
"It is expected to move over land throughout the day," he said.
"A pretty strong monsoon is affecting all of the Gulf of Carpentaria with heavy rainfall pretty damaging winds and also abnormally high tides.
"The main towns we are concerned about are Aurukun, Weipa, Torres Strait Islands and through Burketown, Normanton, Karumba, Kowanyama for very heavy rainfall.
"There is some pretty dangerous weather about.
"The low pressure system at this stage is moving pretty slowly and developing very slowly as well."
