The weather bureau predicts a category one tropical cyclone which has formed off the Queensland coast will be very weak by the time it reaches the Northern Territory.
Tropical Cyclone Zane is currently about 600 kilometres north-east of Cooktown and moving west towards Cape York Peninsula at 17 kilometres an hour.
With wind gusts at the centre of about 100 kilometres an hour, it is expected to cross Cape York late Wednesday night or early Thursday morning.
A cyclone warning has been issued for Queensland coastal areas between Cape Tribulation and Cape Grenville, where the cyclone is expected to bring strong gales as it makes landfall.
The bureau says communities north of Cape Grenville to Mapoon and the Torres Strait Islands should also be on alert.
Forecaster Sally Cutter says all indications are the cyclone will be broken up by unfriendly weather conditions before it hits the Northern Territory.
"It's highly unlikely Cyclone Zane will reach the Top End," she said.
"What we will see is an increase in humidity brought across in the good easterly winds to the south of the system, being brought across to the Top End.
"So there will be an increase in shower and storm activity late in the week.
"But we won't actually experience a cyclone.
"It's just moving into a really unfavourable environment.
"One part, the low part, is heading off west.
"And the high-level part gets pushed off down to the south-east, so it just gets ripped apart."
