A CYCLONE warning is current for remote communities north and east of Darwin as a tropical low develops off the Top End coast.
The weather bureau expects a category one cyclone to form early on Christmas morning, before intensifying into a category two system later in the day.
Residents in an area stretching from from Cape Fourcroy to Milingimbi, including the Tiwi Islands, Cape Don and Croker Island are being warned to prepare for an impending cyclone.
The weather bureau predicts a category one system will form in the area around 4:00am (ACST) tomorrow and it is then expected to strengthen into a category 2 cyclone around 10:00pm on Christmas night.
The bureau says the system should remain slow moving north of the coast over the next 24 hours, before heading south.
