An Australia-wide storm event is set to bring even more rain this weekend, with all major cities forecast to be wet and cloudy.
Persistent rain is forecast to batter central and northeast Queensland from Friday bringing heavy rain from Longreach down to northeast NSW.
That wet weather system is expected to form a rain band that will move east towards Brisbane.

As this is happening a separate system in NSW will also move north towards the Sunshine State, creating wide spread storm spanning from Queensland’s central coast to NSW’s north on Saturday morning.
Weatherzone meteorologist James Rout said the rain will bring dangerous conditions along Queensland’s south coast and NSW’s north coast.
‘The strongest winds will develop Friday night and Saturday morning and could reach up to 80km while waves could reach up to 6metres,’ he said.
The heavy rain and showers are forecast to hang around Sydney through to late next week
Windy conditions could also affect NSW’s Illawarra region and Sydney.
Mr Rout warned the heavy rain could cause flooding in already saturated areas.
‘There’s a chance of flooding in southeast Queensland and northeast NSW overnight and tomorrow morning,’ he said.
‘Inland regions should be on alert for minor flooding, particularly the Northern Rivers in NSW and the Darlings Downs and Granite Belt in Queensland.’
Mr Rout urged residents in these regions to monitor flood alerts.
Rain is expected on Australia’s east and west coasts from Friday with three major wet weather systems set to bring several months worth of rain and minor floods
The rain will ease in Queensland’s over Saturday afternoon with spiralling winds forcing heavy rain over NSW’s central coast by Saturday night.
The storm is forecast to centre over Port Macquarie alongside bringing windy and dangerous conditions.
Light showers are expected to spread to Moree, Lismore and Newcastle.
The storm system will begin easing on Sunday morning but southerly winds will continue to bring light showers the Blue Mountains and Canberra until late next week.
Sydneysiders can expect up to nine days of rain before showers finally clears late next week.
Wet weather in Sydney will be worsened by a positive Southern Annular Mode that is set to stay for about two weeks
‘Southerly and easterly winds will clear on Wednesday before a new system moves in on Sydney from the west on Thursday,’ Mr Rout said.
He said a high pressure system is expected to ease the rain next Sunday and give Sydney residents a couple days of sunny weather.
Further down south, Melbourne is forecast to see light showers on Friday morning which will ease heading into the afternoon.
It’s a similar story for Saturday with light showers expected for the morning but easing later in the day.
Melbourne and Sydney are forecast to see showers over the weekend, heading into next week
The city is expected to stay cloudy heading into next week alongside minimum temperatures under 10C and maximums in the mid teens.
Heavy rain driven by a low pressure system and trough will move in on WA’s coast from Friday afternoon.
Overnight the system will form into a rain band that will move east throughout Saturday and slowly ease on Sunday as it moves over Alice Springs.
The heavy rain system is set to bring several months worth of rain to some areas set to see up to 25mm.

Darwin will dodge most of the rain but will stay cloudy over the weekend with possible light showers early Saturday morning.
Tasmania is forecast to cop the tail-end of the QLD and NSW heavy rain system with light showers forecast through to early next week.
Adelaide will see some of the cloud from the system but is not expected to see any rain.
While many flooded towns are still reeling from the devastation caused by La Nina, meteorologists warned a new wet-weather system is on the way, a Southern Annular Mode.
‘The Southern Annular Mode, or SAM, is a climate driver that lasts a couple of weeks,’ Mr Rout said.
A positive Southern Annular Mode is expected to bring more rain to southern and southeastern Australia for the next two weeks
‘It’s a belt of high pressure that goes around the globe and sometimes it’ll sit further south or further north.
‘At the moment it’s sitting further north, so in a positive position, which blocks cold fronts from travelling further up into Australia and concentrates rainfall in Australia’s south and east.’
SAM’s positive position is expected to last for about two weeks.
The positive SAM means NSW and ACT can expect a very wet start to Spring with parts of the states forecast to get more than 300mm in the four weeks.
