More wet and wild weather threatens to rain down Australia’s east coast even after the La Niña summer ends.

South-east Queensland is at particular risk of being hit by a ‘zombie’ cold air vortex, with an ocean temperature anomaly developing off the Gold Coast.

The Bureau of Meteorology is still predicting that the wet weather will ease in January and bring with it a reprieve from months of rain.

However, the presence of a “cold pool” developing off the Queensland/NSW border could spell trouble for the east coast as the rain is set to end.

It is possible that below average water temperatures could mix with warmer water, leading to convection and another heavy rain event.

“There’s going to be a warming trend along the coast between January and February and if we get some warming temperatures between that cold pool and the coast it’s really going to feed off the moisture which I think should cause significant flooding for SEQ and NSW ” said the founder of Brisbane Weather Courier Mail.

“If this happens, parts of southern Queensland and New South Wales could face the worst flooding since the 1800s.”

The Bureau of Meteorology still predicts that rain will return to normal levels at the end of La Niña in early 2023, but cannot completely rule out heavy rain in January.

“It is not possible to predict rainfall that will lead to specific flooding in a local area more than 3-5 days in advance,” a BOM spokesman said.

More rain would spell disaster for Australia’s east coast, where New South Wales and Queensland are already suffering major flooding.

A ‘triple threat’ weather event is expected on the East Coast in the coming days, with heavy rainfall and possibly severe thunderstorms expected.

New South Wales was hit with the heaviest rain and more dangerous weather was expected during the week.

The wild weather is set to culminate over the weekend when a band of rain passing through NSW “develops into a low pressure system that strengthens [the weather]Sky News meteorologist Rob Sharp reports.

Rainfall is expected to be around 50mm across most of New South Wales, with showers of up to 100mm in parts of the state.
