Tropical Cyclone Narelle crossed the eastern coast of the Top End in the early hours of Sunday morning as a Severe Category 3 system. It has since been downgraded back to a tropical low, but as it moves towards the west, continues to bring heavy rain, damaging wind and flooding risk to communities right across the Top End.

First, let's have a look at overnight satellite imagery. And we can see here on Saturday night Severe Tropical Cyclone Narelle moving towards the eastern coast of the Gulf, crossing just near Cape Shield in the early hours of Sunday morning. It did then continue moving over land and gradually weakening back into a tropical low.

But it is still drawing a lot of tropical moisture down from the north, with heavy rain as well as strong and damaging winds wrapping into the centre of the system itself. Overnight, we did see some pockets of heavy rainfall about the coast, with some locations recording more than 100 mm, and we also did see a number of locations recording wind gusts of more than 90 km/h.

But this is quite a remote part of the country, and so the observations network is quite sparse. So it is likely that we did see much stronger wind gusts right near where the centre of the cyclone did cross. And so with Tropical Cyclone Narelle now an ex-tropical cyclone, we have now cancelled that Tropical Cyclone Warning across the Top End.

However, you will notice that we have issued a new Tropical Cyclone Warning, and that includes the northern parts of the Kimberley coast in Western Australia as the low tracks towards the west. And we will look at that in just a moment. Although Tropical Cyclone Narelle is now a tropical low, we are still experiencing and expecting severe weather across the Top End.

We do have a Severe Weather Warning current for heavy to intense rainfall and damaging winds. This extends from eastern parts of the Top End through Katherine and towards the west coast, and also takes in the Darwin area. As the low pressure system moves towards the west during Sunday, we see heavy rainfall totals up to 230 mm over the 24 hour period, and even higher localised falls, particularly just to the north of Katherine.

And we may also see damaging wind gusts, particularly on the southern flank of this low pressure system. Additionally, we do have abnormally high tides across parts of the Gulf Coast, with very strong winds still pouring onto the coast, and we will see these conditions gradually easing from the east as we head into Sunday night and also into Monday morning.

Now, having a look at the latest flooding situation. We still do have Flood Watches current right across northern Australia. For Queensland river levels remain high, so do check latest conditions before you head out there.

But through the Top End, we do have Major Flood Warnings for the Katherine, Waterhouse and Daly rivers. With rainfall totals expected to exceed 200 mm, we are expecting to see the Katherine and Waterhouse rivers return to major flooding, and for the Daly River that is already in major flood, we are expecting to see that major flood peak maintained for quite some time.

And we also do have a Flood Watch current which extends all the way towards Broome in Western Australia. So now let's have a look at the track map again.

For the rest of Sunday we see Ex-Tropical Cyclone Narelle moving towards the west over the Top End, and by Monday morning it is expected to move over the Gulf of Joseph Bonaparte. And we do have a Tropical Cyclone Warning current all the way from King George River mouth over towards the Northern Territory border.

It really only has a low chance of becoming a tropical cyclone over open water, but we are still expecting to see gale force winds within this warning area on Monday. Now, as we head into the next few days after that, we see the tropical low moving over the northern Kimberley, bringing heavy rain and also possibly damaging winds.

And then as we head into Tuesday, it is expected to rapidly intensify back into a tropical cyclone as we look into Wednesday, and by Thursday morning could reach severe category three strength. At this stage, it is expected to remain off the coast, where we could still see very strong to gale force winds right along the coast, as well as large waves and showers pushing down into the second part of next week.

And so now what does it look like towards the weekend. Well, we do see the models continuing to start to curve the tropical cyclone back towards the Western Australian coastline, but there is still a range of scenarios still possible. One scenario does keep that tropical cyclone well off the coast, but still bringing some large waves and winds onto the west coast of Western Australia.

But another scenario which is possible, that the tropical cyclone does actually curve a little bit further towards the east and move over the Gascoyne and also midwest coast of Western Australia, potentially bringing showers down towards the Wheatbelt and even as far south as Perth.

So if you are across Western Australia in the coming week, do check with that latest track map as well as forecast over the next few days. And so with Tropical Cyclone Narelle now an ex-tropical cyclone, we are still anticipating severe weather right across the Top End this weekend.
