Australia’s east coast is set for another drenching today with up to 100mm of rain bringing flash floods and power outages.
The Bureau of Meteorology issued a severe thunderstorm warning late on Tuesday for parts of the northern rivers, mid north coast, north west slopes and plains and northern tablelands forecast districts.
Rain will also hit Sydney where forecasters predict 6-25mm on Wednesday and 15-35mm on Thursday.
In Queensland, tropical cyclone Uesi is threatening to cause four-metre swells and coastal erosion after forming in the Coral Sea northwest of Vanuatu.
The cyclone, 1,400km off Australia, is tracking south to south-southwest and is expected to affect conditions from Fraser Island to northern NSW.
It is forecast to weaken as it approaches the coastline and is not expected to make landfall.

In the northern rivers, Byron Bay and Tweed Heads could each receive 15-50mm on Wednesday. On the mid-north coast, Coffs Harbour could get 15-40mm.
The BOM is saying 15-45mm is possible in Nowra on Wednesday, while on Thursday the South Coast town could get 40-80mm.
Also on the South Coast, Huskisson could get 20-60mm of rain on Wednesday and 40-80mm on Thursday, while Ulladulla could receive 45-90mm on Thursday.
The NSW coast was drenched over the weekend, with up to 550 millimetres of rain falling across parts of the northern rivers, mid-north coast, Central Coast, Sydney, Blue Mountains and the Illawarra.
Sydney recorded its heaviest rain in three decades and was battered by gale-force winds, with emergency services on Tuesday left to clear fallen trees, remove debris and extract cars from floodwaters.
The SES on Tuesday night said it had received some 12,951 requests for help since last Wednesday night, with 10,660 call-outs completed.
Tens of thousands of NSW households were still without power on Tuesday night, with Ausgrid asking customers to prepare for outages into the weekend.
Residents in New South Wales have been warned to prepare for flooding and property damage, the State Emergency Service said.
Those with properties at risk of inundation should raise moveable items such as furniture as high as possible onto benches or tables, placing electrical items on top.
Farmers on low-lying land close to rivers and creeks were urged to monitor livestock, pumps and other equipment.
There are fears another storm this weekend could bring more coastal erosion to the northern beaches area of NSW.
In Queensland, flood warnings remain current for coastal catchments stretching from Bundaberg to the NSW border, with the southern inland also bracing for heavy falls.
The region’s catchment areas are saturated after days of rain, leading to heavy runoff and possible flash flooding, Bureau of Meteorology forecaster Kimba Wong says.
‘There has been significant rainfall and as the catchment is very wet, its capacity to soak up more rainfall is reduced,’ Ms Wong said.
‘So when we have the significant rainfalls that we have seen in recent days, there can be rapid responses from the rivers with the catchments so wet.’
More rain is also forecast for the drenched towns of Dalby, Oakey, Applethorpe, Warwick and Roma, which have already surpassed their average February rainfall total.

Oakey and Warwick exceeded their monthly average in a day.
‘We are expecting further showers and thunderstorms to pop up in the next couple of days, with the potential for heavy rainfall continuing through southeast Queensland,’ Ms Wong said.
‘Widespread rainfall totals (of) 50 to 100mm are not out of the question and certainly some higher rainfall total will be dotted in the mix as well as severe storm pop-up.’
Shark nets and baited hooks have been pulled from all Gold Coast and Sunshine Coast beaches, Rainbow Beach, Bribie Island and North Stradbroke Island ahead of the wild weather.
The falls have been welcomed across the water grid, with storage capacity at almost 60 per cent, rising from 56.4 per cent on February 7.
