Tropical Cyclone Owen is expected to U-turn away from the Northern Territory coast before gathering force and striking Queensland but that's taking longer than expected leaving residents with a nervous wait.
Owen on Thursday afternoon was near the coast in the Gulf of Carpentaria with inland Borroloola, with a population of nearly 900, the nearest town at risk from gale force winds.
People were warned to expect gale force to very destructive winds between Numbulwar in the NT to Aurukun in Queensland.
In Queensland, the state was on an emergency footing with people in Pormpuraaw on emergency alert, battening down for the destructive winds expected there from Friday afternoon.
The cyclone could also spark flooding and landslides in other parts of the state which is still recovering from its recent bushfire crisis.
Authorities are taking no chances and have already evacuated some medically vulnerable residents from the danger zone.
In the NT, the Bureau of Meteorology's Laura Boekel told reporters that Owen was expected to head back towards Queensland and build from a category three to a four system.
But it hasn't yet happened.
"The U-turn has taken a little bit slower and is a little bit further to the coast than we were expecting yesterday," she said.
"Systems in this area are notoriously erratic and move quite quickly and the situation can move quite quickly as well."
If it moves further south than expected, Borroloola won't cop the brunt, but winds could damage electricity sources, houses and caravans.
Hurricane force winds of 120km/h with gusts of up to 205km/h and rainfall of up to 200mm are expected on the coast between Port Roper and Port McArthur.
Dangerous storm surges and flash flooding are possible.
The Macarthur River Mine port and loading facility at Bing Bong, have been evacuated.
NT Police rescued three fishermen in distress when their boat failed in the Gulf and their EPIRB was activated on Wednesday.
The few people living in the affected coastal area had been spoken to or left, including a man who lives alone on one of the nearby Pellew group of islands, police regional controller Travis Wurst said.
Schools were closed and emergency centres opened as communities in the firing line braced for winds that could peak at about 280km/h.
Owen is expected to head south after crossing the peninsula, bringing rain that could cause flash flooding to Queensland's east coast.
Premier Annastacia Palaszczuk says authorities are worried about heavy rain in central Queensland, where landscapes have been destroyed by recent bushfires. Eungella, inland from Mackay, is of particular concern.
"Once you have bushfires through an area, with large amounts of rain, there is then the potential for landslides," she told reporters.
Queensland BOM senior forecaster Richard Wardle said upper trough in the west of the state was also going to generate extreme weather over the parched southern interior over the next few days.
While decent rain was expected, he stopped short of calling it drought breaking.
Queensland's disaster coordination centre has been activated and the state's disaster management committee will continue to meet as the cyclone nears.
Extra rescue and emergency crews have been sent into the cyclone warning area.
