Monster Cyclone Jasper is on track to hit parts of Queensland and has intensified into a Category 4 storm.
The tropical cyclone is moving south through the northeastern Coral Sea, about 350 kilometers northeast of Cairns.
Weather officials say the cyclone could weaken this weekend as it turns west towards the Queensland coast, before regaining its ferocity when it hits land.
The Bureau of Meteorology said it is not yet known when the cyclone will make landfall, but several towns along Queensland's north coast will be affected.

“While the timing of a coastal impact remains highly uncertain, the greatest risk of a cyclone impact is between Cooktown and Mackay, including Cairns and Townsville,” they said.
'As Jasper approaches the coast there is a risk of re-intensification and the potential for serious consequences.'
Popular Australian weather tracker John's Weather Channel said in a post on Facebook that the cyclone was likely to make landfall in Cairns but could hit as a category three.
“In terms of strength, some models are showing the upper end of Cat (Category) 2, while some are re-intensifying close to the coast and landing as Cat (Category) 3,” the forecasters said.
The 'unusual' cyclone was moving south-southwestwards in the Coral Sea, with gusts expected to reach 195 kilometers per hour on Thursday evening.
The Bureau of Meteorology issued a warning on Thursday afternoon saying the severe tropical cyclone could become a category five by late Friday.
Jasper is not only the first tropical cyclone of the season, but it is also believed to be the first to emerge off the coast of Australia during an El Nino in December.
“It is rare to see a cyclone in December, let alone one involving El Nino,” an agency spokesperson said.
