Triple Antarctic blast smashes Australia's southeast
Parts of Australia’s south have been battered by a triple antarctic blast with heavy rain and damaging winds hitting hard.
South Australians are experiencing damaging winds, rain and hail when one of the biggest storms of the season hits the state.
Bureau of Meteorology senior forecaster Matt Bass said the front would cross the state today and hit Adelaide's CBD later in this afternoon.
"What we're looking at is quite a windy front coming through, one of the most significant fronts we've seen so far this winter," he said.
"There is a risk of damaging winds across a broad area of the state, roughly south of Streaky Bay to Port Pirie to Renmark - this includes the Adelaide metropolitan area.
"The heaviest rainfall and strongest winds for Adelaide are likely to be from mid-afternoon through to the evening, including the afternoon commute, so drive to the conditions and stay safe."
SES chief of staff Trevor Arnold expected driving conditions and outdoor activities to become dangerous.
"We're asking communities to be aware this could cause minor street flooding," he said.
"We're urging motorists to not drive, ride or walk through floodwater and keep clear of creeks and storm drains. And also check your gutters."
The Mount Lofty Ranges, parts of the lower southeast of the state and Kangaroo Island are expected to receive between 15 and 30mm of rainfall on Wednesday, with rainy conditions to continue to the end of the week.
Wave heights of more than five metres are expected along exposed southern coasts, while heights could increase to eight metres by Friday.
Wet and damaging winds have also hit central parts of Victoria as a cold front covers the state.
Damaging winds up to 70km/h with peak gusts to 100km/h are expected above coastal parts of western Victoria this afternoon, extending to central and eastern parts, the Bureau of Meteorology warns.
Damaging wind gusts of up to 90 km/h are also expected in remaining parts of the state's southwest, likely associated with showers or thunderstorms.
Locations which may be affected include Hamilton, Warrnambool, Portland, Kyneton, Ballarat, Mt Buller, Mt Hotham and Falls Creek.
Further north, NSW has remained dry however there are hazardous surf warnings in place for coastal areas and western suburbs saw frost and early morning fog.
In Queensland, showers are likely along the northeast coast with chances of showers in the central inland.
It will be fine and mostly sunny elsewhere according to the Bureau of Meteorology.
In Western Australia, there is a strong chance of showers along the state’s south coast, with additional wet weather around Perth and Jurien Bay clearing up by this afternoon.
In Tasmania, light rain in the north and west will increase to heavier showers later this afternoon.
North to northwesterly wind gusts will also increase as the day continues.
Showers are less likely for the Australian capital however a cold front will skim across southern districts and patches of frost and fog will make the morning drive into work tricky.
In the Top End, there is a slight chance of showers along the northeast Arnhem District coast and some cloud in other areas.
