Two states are in line for more drenching, amid warnings some residents in one could find themselves isolated by flooding.
Sydney’s drenching start to the year is set to continue this week as some Queenslanders brace for the possibility of being cut off by major flooding.
According to the weather bureau, Sydney has experienced more rainy than sunny days this year.
Of the 142 days since the new year, 94 have been wet, driven by the La Nina event in the Pacific.
La Nina is not expected to ease until late autumn and more rain is on the way in Sydney for the rest of the week.
Up to 20mm was forecast for Sydney on Sunday, with moderate falls of between 15mm to 25mm likely on Monday.
The trend would continue on Tuesday with falls of 8mm to 20mm and then 6mm to 15mm on Wednesday.
The wet weather is tipped to begin clearing on Thursday with minor falls forecast for the rest of week.
It comes after Queensland endured a drenching with some parts of the state copping over 100mm over the last 24 hours.
Maroochydore on the Sunshine Coast had 122mm of rain over that period, according to the bureau.
At Burleigh Waters on the Gold Coast, 78mm was recorded over the last 24 hours.
The trough moving down the coast dumped heavy falls on some parts of the south east corner and is expected to move offshore on Sunday.
Up to 15mm is forecast for Brisbane on Sunday, with up to 25mm for the Gold and Sunshine Coasts.
The rain is expected to stick around the south east corner until Friday, though lighter falls are expected.
A raft of flood warnings for up and down the Queensland coast have been issued.
There has been major flooding at Condamine in the Western Downs after falls of up to 30mm around the catchment on Saturday.
The Western Downs Regional Council warned residents to prepare for the possibility the Condamine Bridge could be closed.
The Condamine River was expected to peak at 9.30am on Sunday and it’s expected to remain at major flood levels into the rest of the day.
There has also been major flooding along the Balonne River to Surat, with water flowing downstream from the Condamine River.
The bureau on Sunday morning issued a gale warning for the Capricornia Coast, in central Queensland, as well as offshore at the Great Barrier Reef.
There is also a strong wind warning for much of the Queensland coast from the Cooktown Coast down to the Gold Coast for Sunday.
The bureau has said a strong wind warning will be in place for the Fraser Coast, Sunshine Coast and Gold Coast on Monday.
