More thunderstorms and rain on New Year's Day

Severe thunderstorms have eased across eastern Australia but are expected to redevelop around eastern Queensland and northeast NSW from December 30 into the New Year.

Parts of Australia are set to face wet and potentially wild weather on New Years Eve and New Year's Day.

BoM senior meteorologist Sarah Scully said isolated thunderstorms are possible for parts of Queensland, NSW, Victoria and South Australia.

"Severe thunderstorms are possible in Queensland between St Lawrence and Redcliffe, although activity will not be as widespread compared to previous days," Ms Scully said.

"Isolated gusty thunderstorms are also possible over western South Australia."

Showers and storms are possible across parts of southern and eastern Australia, mainly NSW, eastern South Australia, and northern Victoria on December 29.

There is a risk of severe thunderstorms in Sydney, the Blue Mountains and the Hunter regions.

Severe thunderstorms will become more widespread from this weekend concentrating in north-east NSW, and south-east and central Queensland.

BoM said there are indications that isolated, very dangerous thunderstorms with destructive winds, giant hail and intense rainfall may be possible across southeast Queensland on Saturday.

BoM has encouraged the community to stay up to date with the latest forecasts and warnings using the BOM Weather app and website.

Queensland will also experience heatwave conditions along the east coast affecting Brisbane, the Sunshine Coast and areas surrounding Cairns.

Northern and Western Australia will also face heatwave conditions with temperatures reaching the mid to high 40 degree Celsius in some areas.
