Key Points

• Ex-cyclone Kirrily has finally left Australia after dumping several months' worth of rain in NSW.
• Thirteen flood warnings remain active in Queensland after widespread heavy rainfall in the past week.
• Showers and thunderstorms are expected in northeast NSW, southeast Qld and northern Qld in the coming days.

Ex-cyclone Kirrily has finally left Australia after dumping several months' worth of rain in NSW while the flood emergency remains in parts of Queensland.

Some 86 millimetres fell at White Cliffs in northwestern NSW in the 24 hours to 9am on Tuesday — four times the February average, according to Bureau of Meteorology senior metrologist Dean Narramore.

He said much of the state was hit with 30mm to 50mm, noting 86mm was recorded at Kiama on the south coast and 64mm at Orange.

"(It was) widespread soaking rainfall, some of those fell in quick time, which led to localised flash flooding particularly around the White Cliffs area," Narramore told AAP.

The SES rescued two people from cars at Albion Park on the south coast and one at Campbelltown, with volunteers called to 174 incidents in 24 hours.

The Warragamba Dam in the Blue Mountains is at 97 per cent capacity, up from 94 per cent on October.

Queensland flood warnings remain after widespread heavy rainfall

Thirteen flood warnings remain active in Queensland after widespread heavy rainfall in the past week.

Major warnings have been issued for the state's northwest at the Burketown airstrip following rapid river rises over the weekend and Walkers Bend along the Flinders River.

Major alerts are also in place for towns along the Moonie and Balonne rivers in southeast Queensland.

Narramore said the area of greatest concern was Burketown, which was expected to reach flooding of 6.5 metres on Tuesday evening.

"It's not going to be as bad as what we saw in 2022 where we saw it reach over seven metres but still, any flooding is bad flooding and definitely going to impact Burketown," he said.

He expected showers and thunderstorms in northeast NSW, southeast Queensland and northern Queensland in the coming days, but said the conditions were still considered "typical wet season" activity for this time of year.
