Weather Sydney, Melbourne, Brisbane, Canberra: Heavy snow strikes cutting off thousands from Sydney

>

Thousands of people have been cut off from Sydney after two major roads are closed forcing drivers to wait in freezing conditions. 

The Great Western Highway in Katoomba, which connects the Blue Mountains to the the city, has been closed after a minor accident on Wednesday morning. 

Motorists have been warned the highway may not reopen until 10 or 11am with the closures to cause mayhem during peak hour traffic. 

The minor accident is believed to have been caused by black ice on the road with police on the scene to ensure the ice melts before the road reopens.

The winter wonderland comes as an icy polar blast struck Australia’s east coast on Tuesday bringing wild weather including heavy rain, hail stones and snowfall. 

The cold front has moved through Tasmania, South Australia and Victoria before making its way northeast across the NSW and the ACT.

The mercury was predicted to reach a low of 7C in Sydney and Melbourne, with the southerly wind chill is making it feel like sub-zero temperatures.

Sydney experienced its coldest afternoon of the year on Tuesday with the cold front causing temperatures to plummet to just 10.2C by 3pm – which felt more like 1.8C with the addition of the rain and wind. 

Residents in NSW’s Central Tablelands awoke to see their suburbs transformed into winter wonderlands while one man snapped a photo of the snow flurries at Katoomba train station late on Tuesday night.

Joel Pippard from Weatherzone said the snow fell across NSW’s Central Tablelands from about 4pm on Tuesday to 2am on Wednesday morning. 

The forecaster estimated snow had gotten as low as 600m to 700m in some areas with about 5 to 10cm falling in Leura, Blackheath, Lithgow and Orange. 

He said those areas are unlikely to see more snow tonight as the cold front responsible moves off the NSW coast to New Zealand but said the alps and snow slopes could see some ‘light dustings’.

Yoska Hernandez from Weatherzone said parts of NSW should expect some snow on Wednesday morning with the wild weather forecast to last until the end of the week. 

‘This will be for parts of the Central Tablelands, Bathurst, Lithgow, Orange and Katoomba and in the Northern Tablelands as well,’ he said on Tuesday. 

‘We could see snow accumulations of about five to ten centremetres of snow.’

The sudden drop in temperatures and rainfall has been caused by a cold air mass with southerly winds blowing in its wake. 

Sydney will see moderate rain Tuesday night with showers expected to continue until the weekend.

The storm system is going to move as far as Brisbane with showers expected to fall into the evening before clearing to a warmer 19C on Wednesday. 

Light showers will also hang around Melbourne on Tuesday night and won’t ease until Friday. 

The bitter cold snap has also seen heavy snowfall in Victoria and NSW’s highland regions with powder forecast down to 800m with up to 30cm possible.

Snow was forecast to fall above 800m in Victoria and NSW on Tuesday with up to 30cm of settled snow possible (pictured, forecast for snow on Tuesday)

Canberrans and the ACT were drenched by the southerly buster rain band on Tuesday with temperatures dropping to -2C and expected to get even colder as the evening goes on.

While the nation’s capital will remain cloudy for the rest of the week, rain is forecast to ease heading into Wednesday. 

Hobart is forecast to see separate showers Tuesday and Wednesday after days of bitterly cold conditions ravaged Tasmania.

In central Australia minimum temperatures are forecast to be just above freezing for Alice Springs overnight

Darwin will stay sunny with maximum temperatures of 33C and minimums around 20C expected through to early next week.

Adelaide avoided the brunt of the rain band but should expect light showers through to the end of the week.

Perth is set to see cloudy weather coupled with maximum temperatures in the low 20Cs through to Friday before possible showers move in on Saturday.
