Residents across New South Wales' flood-ravaged north have been hit by a severe thunderstorm warning.
The Bureau of Meteorology (BoM) has issued the warning for damaging winds and heavy rainfall for parts of the Northern Rivers, Mid North Coast, Hunter, North West Slopes and Plains and Northern Tablelands Forecast Districts.
The BoM said it is likely the storm may lead to flash flooding.
"A humid and unstable air mass east of an inland trough will produce thunderstorm activity across the northeast quarter of the state this afternoon and early evening," the BoM said.
"Locations which may be affected include Tenterfield, Glen Innes, Murwillumbah, Casino, Kyogle and Tabulam."
A severe thunderstorm warning has also been issued for the Gold Coast in Queensland.
Flood warnings in place
Earlier today, the BoM warned up to 25mm to 50 mm could fall across areas of the NSW mid-north coast, Northern Rivers and Hunter regions.
Several flood warnings have already been issued for the state, ranging from minor to major alerts.
A moderate flood warning has been issued for Wollombi Brook at Bulga after 40 to 50mm of rain fell in the area since 6am.
"Further moderate to heavy rainfall is possible into the early afternoon," the BoM said.
Minor flooding for the Bellinger, Nambucca and Severn rivers is also possible.
"A separate minor to major Flood Warning is current for the Culgoa, Birrie, Bokhara and Narran rivers," the BoM said.
Residents can stay up to date with the latest warnings here.
People have been urged to take care on the roads over the coming days with rain expected to continue.
'News that no-one in NSW wants to hear right now'
Speaking to Today yesterday senior meteorologist at the BoM Jonathan How said the heaviest falls will be felt on Thursday and Friday.
"It is the news that no-one in NSW wants to hear right now...across eastern NSW, there's plenty of wet weather to come," he said.
"We're set for another seven days of showers, rain and storms - really anywhere north of Wollongong up towards Sydney and Northern Rivers as well.
"Isolated places could see 200mm fall from tomorrow and into the weekend."
Firefighters share photos of inferno threatening homes
The Northern Rivers was hard-hit by the deadly flood crisis which left towns such as Lismore and Woodburn underwater.
Flooding also occurred in Ballina and as the waters receded a housing crisis only got worse in Byron Bay.
Byron Community Centre General Manager, Louise O'Connell said the coastal town had the highest number of homeless, outside of metropolitan capitals Sydney and Melbourne, before COVID-19.
Then the floods came.
"We have 15,000 people displaced from floods," she told Today as she announced the opening of a new hub to provide relief for those in need.
"It was already a housing emergency. So it is very scary where we are at now.
"We can operate this until the end of the year. I have no full-time staff here. I would love to put on some full-time social workers. We really need some more help."
Rain could be heading for WA
Some western parts of Western Australia could be hit with damaging winds and rain as Tropical Cyclone Charlotte swirls offshore.
Weatherzone is tracking the storm system but said its future path is uncertain, meaning it could impact parts of the coastline.
"There is potential for ex-tropical cyclone Charlotte to impact the west coast of WA anywhere between Carnarvon and Lancelin from this weekend into early next week," it said,
"If it does approach the coast, damaging winds and heavy rain could develop.
"However, the system may also remain offshore and spare WA from any severe weather impacts."

Weatherzone explained the storm system is weakening over the ocean.
"It was downgraded to category two system early on Thursday morning," it wrote.
"At 6am AWST on Thursday, Charlotte was located around 500km to the northwest of Coral Bay and moving slowly towards the southwest."
