Heavy rain is set to lash almost every state in the next 10 days, exacerbating flood risks in regions that are already on high alert.
Fourteen active flood warnings remain as major flooding continues on the Macquarie, Namoi, Bogan and Lachlan rivers in NSW.
“It‘s not going to rain everywhere, every day, let’s be clear about that, but a series of weather systems will deliver rain to virtually all parts of Australia over the coming 10 days,” Weatherzone meteorologist Anton Sharwood said.
NSW and Victoria are expected to be hit with the heaviest rain, followed by Western Australia.
The Bureau of Meteorology has warned the deluge will exacerbate flood risk.
“Flooding continues across many inland catchments and many other catchments are saturated,” the bureau said.
“Showers and thunderstorms moving through with a trough over the next couple of days may exacerbate existing flooding and possibly lead to renewed riverine flooding.”
Residents are urged to monitor local alerts for further warnings.
“Numerous weather systems are expected to impact the country in the next 10 days or so,” Mr Sharwood said.
A low pressure trough could deliver significant unseasonal rainfall to the Kimberley and Pilbara districts in northwest WA early next week.
“Those two regions experience almost no rainfall on average at this time of year,” Mr Sharwood said.
Broome, on the Kimberly coast, typically endures its two driest months in September and October, with an average of just 1.4mm in each month.
Yet, Broome may experience between 50-80 mm over the course of the next 10 days.
Darwin is likely to get an early October drenching, although this is not unusual for the Top End at this time of the year.
Showers and the chance of afternoon thunderstorms persist until Sunday with the worst rainfall expected on Thursday when up to 15mm is forecast in a single day.
New South Wales
A strong wind warning is in place for the NSW coastal regions of Byron Bay and Coffs Harbour throughout Tuesday.
There is a high chance of showers and the possibility of thunderstorms in Sydney from Tuesday to Thursday.
A strong south-westerly wind is likely to arrive by Thursday afternoon with gusts of up to 40km/h.
A minor flood warning remains in place for the Orara, Gwydir, Murrumbidgee, Warego and Paroo rivers.
A low pressure system will bring rainfall to the flood watch area on Tuesday, as moderate flooding is occurring at Stevens Weir and Barham on the Victorian-NSW border.
Catchments in the Flood Watch area are wet as a result of the recent rainfall, with elevated river levels within some catchments.
Up to 30mm of rain is forecast for the central and western parts of the state with some isolated areas forecast to receive a downpour of up to 50mm.
Minor flood warnings are current in the Loddon and Kiewa Rivers.
A strong marine wind warning is in place for the East Gippsland coast, with up to 30mm of rainfall likely to arrive by Wednesday.
A chance of showers will carry through the week in Adelaide, though the southern state is likely to miss the downpour forecast in other states.
No more than 2mm is forecast for any one day in the capital city.
Showers are likely each day for the rest of the week in Hobart where a marine wind warning is currently in place.
The territory is also unlikely to receive the drenching that the other states are forecast to.
Minor flooding is occurring at the Upper Dawson River Catchment and Upper Ballone River where river levels will continue to rise as rain persists throughout the week.
Moderate flooding is taking place at the Bokhara River and Lower Macintyre River as saturated soils are unable to absorb continued rainfall.
Up to 15mm are predicted to fall for the rest of Tuesday with a possible thunderstorm in the afternoon.
A north-easterly wind of up to 25km/h is likely to settle as the evening falls.
