New flash flooding danger as treacherous storm conditions head south

Several towns on NSW’s Mid North Coast are facing the prospect of dangerous flooding while the treacherous conditions which have battered the state’s north and southern Queensland head south.

While the heaviest rainfall subsides after days of wild weather across the area, a severe weather warning now stretches along the coast to as far as Blueys Beach, 130km north of Newcastle.

Heavy rainfall and abnormally high tides are expected between the town and the Queensland border, the NSW State Emergency Service said.

Multiple rivers in northern NSW continued to rise on Tuesday evening. Rain that has already fallen will continue to drive floods higher on Wednesday, the Bureau of Meteorology warns.

Meteorologist Jenny Sturrock said isolated storms will continue in the coming days, which could bring flash flooding.

NSW communities including Lismore, Taree, Scone, Mudgee, Dubbo, Walgett and Narrabri braced for heavy rainfall on Tuesday evening after the BoM issued a severe thunderstorm warning for a large part of the state.

Flash flooding from fresh rainfall could be life-threatening, the BoM warned on Tuesday evening.

Strong winds are also set to continue on Wednesday along the Macquarie and Hunter coasts.

Flood warnings were also issued for much of the Northern Rivers and Mid North Coast, including communities along the Richmond, Wilsons, Hastings, Orara, Macleay, Nambucca, Bellinger and Kalang Rivers.

The BoM said on Tuesday between 400 and 500 millimetres has been recorded in the Northern Rivers and on the Mid North Coast in recent days.

Evacuation order for hundreds remains

An evacuation order from the State Emergency Service remained in place on Tuesday evening from Condong to Tumbulgum and surrounds, with an evacuation warning still current around the Tweed River at South Murwillumbah.

The order came after the Tweed River burst its banks near Tumbulgum on Tuesday, with minor to moderate flooding in the area.

It has been a wild week for weather in NSW and Queensland.

A low pressure system causing strong wind and heavy rainfall combined with king tides to wash away much of Byron Bay's Main Beach on Monday.

On the Gold Coast the weather system also caused massive coastal erosion, with the surf club at Currumbin becoming an island.
