A cyclone WATCH is now in place from Maningrida to Croker Island, including Goulburn Island.

Tropical Cyclone Nathan has been upgraded to a category 2 system and at 10:56pm CST was estimated to be 225 kilometres southeast of Nhulunbuy and 225 kilometres east northeast of Alyangula and moving west northwest at 18 kilometres per hour.

Gales expected between Nhulunbuy and Alyangula in the next few hours as Tropical Cyclone Nathan approaches the Northern Territory.



GALES, with gusts up to 125 kilometres per hour, are expected to develop on the coast between Nhulunbuy and Groote Eylandt tonight or early Sunday morning and extend west along the north coast between Nhulunbuy and Elcho Island, including Gapuwiyak during Sunday morning.


Gales are expected to extend further west between Elcho Island and Maningrida Sunday afternoon and may extend west to Crocker Island overnight on Sunday or Monday morning. Gales may extend to Numbulwar if the cyclone takes a more westerly or southerly track.



DESTRUCTIVE winds with gusts up to 155 kilometres per hour extend approximately 50 kilometres from the centre of the cyclone, and may impact coastal and adjacent inland locations between Nhulunbuy and Groote Eylandt during Sunday morning, extending to Elcho Island and Gapuwiyak later in the morning.


Heavy rainfall, which may lead to flash flooding, is expected to develop across coastal parts of eastern Arnhem Land as the cyclone approaches tonight and Sunday morning.



Coastal residents between Groote Eylandt and Nhulunbuy are specifically warned of a DANGEROUS STORM TIDE as the cyclone centre crosses the coast. Tides are likely to rise significantly above the normal high tide, with DAMAGING WAVES and DANGEROUS FLOODING.

“If you do not have accommodation constructed to the Building Code or are unsure of your present accommodation you should PROCEED IMMEDIATELY to shelter with family, friends, or one of the local emergency shelters. Take your emergency kit and plenty of water with you.


“For residents in other communities under cyclone WARNING now is the time to make final preparations to their home shelter or identify which public emergency shelter or strong building to use and prepare to make your way to the most appropriate of the shelters once they are opened.


“People should now have your emergency kit complete and ready, including ensuring you have plenty of water to take with you or available in your home.


“Private Sector businesses and organisations still open at this time are strongly advised to consider securing and closing their premises. Employers are reminded of their Duty of Care to ensure the safety of any employees still at work.


Communities under WATCH

“For those communities under cyclone WATCH, residents from Maningrida to Croker Island, including Goulburn Island, now is the time to put together your emergency kit, clear your yards and commence home shelter preparations. Fill any water containers you may have to ensure that you have at least three litres of water per person per day for at least 72 hours and fill your vehicles' fuel tanks.


“If you do not have accommodation constructed to the building code or are unsure of your present accommodation you should determine now where to shelter. This may include arranging to shelter with family, friends, or in public emergency shelters or appropriately strong buildings that are available in your community.

“Please ensure that friends, family and neighbours have heard and understood this message, particularly new arrivals to the area.

“Tune in to your local radio and/or television stations for further information and warnings,” said Superintendent Bacon. 



Superintendent Bacon said that the Power and Water Corporation advises that building occupants should fill bath tubs and water containers with water before the cyclone arrives. Do not use chemical or fuel containers to store drinking water. After the cyclone has passed as a precautionary measure, it is recommended that tap water used for drinking and oral hygiene be boiled first and allowed to cool.


Power stations in the communities will continue to operate as long as it is safe to do so. 


After a cyclone, downed powerlines might be live and lethal. Stay away and stay safe.


After a cyclone you should flush toilets with a bucket to reduce the likelihood of blockages.
