The presser has wrapped up so that's where we'll leave our live coverage. 

We'll continue to keep you up-to-date on Tropical Cyclone Fina and the latest advice at abc.net.au/news

If you're yet to prepare a cyclone kit — now could be the time! 

Cyclone kits are essential if you lose power, water or communication.

A kit should include enough to support you and everyone you live with for three days.

Our explainer below lists everything you need to get ready.

Acting Assistant Commissioner O'Brien says people in the Top End should "be prepared, but don't panic". 

"There is no need to panic at the moment," he said.

"My advice is we as controllers have done this many, many times over and we know where we're currently sitting.

"We are very well prepared, very well planned, pre-planned and that's what we ask of the community.

"Just heed the advice that we will be sending out."

He says people can find the latest advice from Secure NT, NTES and the police.

"Now that the EOC [emergency operations centre] is up and running, we will be sending out more information to update the community," he said.

Darwin has not experienced a cyclone since Cyclone Marcus crossed as a category two system in 2018.

It left more than a third of Darwin properties without power.

The strongest cyclone to ever hit Darwin was Cyclone Tracy in December 1974, which devastated the city and killed 66 people.

Cyclone Tracy made landfall as a category four system and at the time was the most compact cyclone on record worldwide.

Mr Snell says there are no plans to evacuate anyone from remote communities and islands "at this stage".

"But that's a decision that will be made by the incident controller in consultation with a whole range of organisations, a whole range of people and directly with the local communities," he said.

Ms Scott says there's a possibility Tropical Cyclone Fina could intensify to a category three system.

"With these systems, they move erratically, and there is always the possibility that it may intensify further into a category three system as it makes its way towards the coast," she said.

"It is forecast to intensify to a category two system overnight tonight, and it's so far the expectation that it will remain at cat two for the coastal crossing. 

"But we can't rule out the possibility of a category three."

BOM senior officer Jude Scott says Darwin can expect "heavy rain and windy days ahead" as the cyclone moves towards the city.

"Tropical Cyclone Fina will first of all make landfall in the Cobourg Peninsula area and then from there travel through the Van Diemen Gulf," she said.

"Now that's a very narrow waterway. It's quite hard to say sort of whether the impacts will be to the north or the south at this early stage of the system, but it's clear that from the way that the cyclone's moving, we're likely to see the impacts in Darwin.

"There will be heavy rain and windy days ahead.

"It's probable that Saturday will be the main day when the cyclone will impact the Darwin area, although depending on how the track moves, that may start from as early as Friday night."

Mr Snell says Darwin residents not living in a home that's up to code may consider going to a cyclone shelter, if Tropical Cyclone Fina was to make landfall near the city later this week. 

"The emergency shelters are not serviced, you have to take all of your own equipment with you, all of your own support with you," he says.

"In developing that plan, you need to take into account what you're going to do with your pets, because most of the shelters do not support pets.

"You also need to establish a way of communicating with your family members, should you be in different locations.

"One of the things of course we all know from the Top End is that communication systems as well as electricity systems and other essential services can be disrupted at this time."

Darwin remains in the forecast track zone but no alert has been issued for the city so far.

Mr Snell says Darwin residents should "have a plan for your family that includes what you were going to do should the cyclone make landfall here".

"You should consider that there are shelters across Darwin, but the general advice in Darwin is that most of our buildings are built to code now, and that the safest place for you to is to actually stay in your residential home," he says.

"But what you should also do and should have been doing for a period of time now is to check to make sure that your emergency kit is ready."

Wayne Snell, chief officer of the NT Emergency Service, says the service has been planning its response in partnership with the police since last Wednesday. 

"That's included preparing all of the volunteer forces to support the police as we transition into the response phase," he said.

"There are units in the Top End of the Northern Territory who are ready, and then there are units south in the Northern Territory who will come through in relief if and when required."
