Heavy rain has fallen over large parts of southeastern Australia overnight, and flood warnings are in place as weather typical of a La Niña summer returns with a vengeance after a relatively dry period over Christmas and New Year.

• Extremely heavy totals were recorded at numerous High Country weather stations to 9 am this morning, with 108.2 mm at Mt Hotham Airport in the Victorian Alps. This was the heaviest January fall in 45 years.
• Omeo, about half an hour south of Hotham on the teblelands just below the mountains, recorded 114 mm, its highest daily rainfall in 10 years.
• The NSW Snowy Mountains and South Coast also recorded falls in excess of 40 mm at several locations.

A moderate flood warning was issued early on Thursday morning for Victoria's Mitta Mitta River, and you should check the Weatherzone warnings page for updates if you live or are holidaying anywhere in southeastern Australia's mountain or coastal districts.

More rain to come

The rain that fell overnight and yesterday could be just a taste of things to come.

As you can see on this morning's synoptic chart, a slow-moving low pressure trough sits over inland Vic, NSW and Qld. It is being fed by a stream of moisture from ex-Tropical Cyclone Seth, and rain and storms are expected to persist for at least the next couple of days.

As we write this story, a significant rainband is centred over the NSW/Vic border region around Albury/Wodonga. It is moving slowly southeast, which could mean more rain on the already very soggy mountain areas and surrounds.

We'll keep you posted throughout the coming days with news of any flooding and/or severe storms in SE Australia. We've also got an eye on Tasmania, where severe weather warnings (heavy rainfall) are in place for several districts.
