There's a high chance the second tropical cyclone to hit northern Australia this year will develop in coming days, the weather bureau has advised.
The likelihood of a tropical low in the Gulf of Carpentaria intensifying into a cyclone increases from very low (less than five per cent) on Tuesday to high (over 50 per cent) on Thursday.
There is some uncertainty the weather system will stay over water, but meteorologist Pieter Claassen said it was likely.
"Conditions are favourable for it to intensify and we are expecting it to remain over water over the next couple of days at least, so it's likely to become a tropical cyclone by Thursday," he said.
A tropical cyclone watch has been declared between Aurukun and Karumba in Queensland's far north as well as Mornington Island.
If it does develop, it will be the second cyclone this year for the region after Tropical Cyclone Imogen crossed the coast near Karumba on January 3.
Systems forming "back to back" is not usual and the bureau forecast an above average cyclone season due to the influence of the La Nina weather pattern.
Cyclones in the region can be slow moving, erratic and change direction, which makes predicting their path more challenging.
Gales with gusts to 110km/h may develop about coastal and island communities late on Wednesday and into Thursday, and the developing system coincides with very high tides.
"If the system does form, it is likely that we'll see abnormally high tides with tides exceeding the highest astronomical tide," Mr Claassen said on Monday.
