And then on Saturday, we see rain and damaging winds building across south-western and southern parts of the state. First, let's have a look at the latest radar imagery.
And we can see here on Friday afternoon, Tropical Cyclone Narelle crossing the coast near Coral Bay and then moving southwards into range of the Carnarvon radar.
With that, we are now seeing heavy rainfall wrapping into the centre of the cyclone and those rainfall totals are building across the Gascoyne coast.
We have also seen significant wind gusts, and those wind gusts are building across the Carnarvon area, where a wind gust of 133 km an hour was recorded.
Further north, we are still seeing damaging to destructive wind gusts, including around the Learmonth area. But as Narelle moves south, those winds will gradually start to subside as we head into Friday night.
Further south, we are also seeing a rain band pushing through the south-west of the state, including around the Perth area, with a lot of tropical moisture pouring down from the north.
We have seen some moderate rainfall totals and isolated thunderstorms around the south-west of the state, and since 9:00 am this morning, rainfall totals across the Perth area have generally been between 20 to 40 mm, but some locations now approaching 50 mm.
And inland, we have also seen rainfall building across the Wheatbelt, and there is more rainfall to come as we head into Friday night and also Saturday across south-western WA.
And so now the latest Tropical Cyclone Warning. Tropical Cyclone Narelle, currently a Category 2 system just to the east of Carnarvon.
But as it's moving south, we have contracted that warning away from the Onslow area, but it does still include areas all the way from Exmouth in the north and down to Jurien Bay in the south, and also inland.
That does still include Carnarvon, Denham, Kalbarri, Geraldton and northern parts of the Wheatbelt. And through this area on Friday night and into Saturday morning, we will also continue to see damaging to destructive winds, heavy to intense rainfall, as well as a dangerous storm surge along the Gascoyne coast.
And now looking at the track map, we can see here Tropical Cyclone Narelle moving southwards along the coast as a Category 2 system through Friday night into Saturday morning, just to the east of Kalbarri and also Geraldton, and into the early hours of Saturday and also the afternoon, it will rapidly weaken back into a tropical low, moving through the Wheatbelt but still bringing heavy rainfall as well as damaging winds.
And because of that, we have also issued a Severe Weather Warning, which extends from the Tropical Cyclone Warning for damaging to destructive winds and heavy rainfall.
That extends all the way from the Gascoyne and northern Wheatbelt just to the east of Perth and down along the south coast, and that does also include Esperance.
Now through this area here, we could see destructive winds of up to 125 km an hour through northern parts of the warning area through Saturday morning as the system pushes down towards the south.
As well, we could also see heavy rainfall, with 6-hourly totals between 30 to 50 mm and higher isolated falls are possible. And because of this, we also do have a Flood Watch current across much of western and south-west WA, with the possibility of flash flooding as well as riverine flooding.
So now, looking at the rainfall expectation as Tropical Cyclone Narelle pushes down through the south, we'll see rainfall building across that warning area, but also building across the south of the state before finally moving off the south coast as we head into Saturday night. And it will ease back to showers on Sunday.
But we can still see here very high rainfall totals across pockets of the south-west and also particularly through that warning area.
And so if you are in that warning area or across the south-west of WA today and into tomorrow, do keep across those latest forecasts and warnings.
You can get those on our website and app.
