Victorians and Tasmanians are being warned to brace for the “coldest day of the year” as two cold fronts smash the two southern states on Sunday.
Bureau of Meteorology senior forecaster Jackson Browne said the cold fronts had started to move across Tasmania and central Victoria on Saturday before the brunt of the winter blast hits in the evening and into Sunday.
Temperatures will plummet to 15 in Melbourne and just 13 in Hobart on Sunday, making it the “coldest day of the year” for the two states.
Victoria can expect overnight lows of 9C.
Mr Browne forecast enormous swell, rain, hail, frost and even low-level snow in areas on higher ground.
By Sunday snow levels would drop to 700-800m in Tasmania, and 900-1000m in Victoria.
“The air is cool enough to support snow right now, but there won’t be snow until this evening and Sunday. Tasmania could even get a dusting in areas on lower ground,” Mr Browne said.
The alpine and Eastern Highlands regions could also see snowfall in Victoria on Sunday.
Mr Brown also warned Tasmanians to expect sea levels up to 10m with gale force winds smashing the western coast.
“We haven’t seen seas this large since about July, 2011,” he said.
“It’s an unusual event from a marine standpoint.”
Mr Browne warned there could even be coastal erosion in sheltered coastal areas around high tide and urged any beach goers to “practice a bit more caution”.
Temperatures in Victoria have already plunged this week, down from 30 degrees on Thursday to 16C on Saturday.
Meanwhile Canberra is expected to plunge below zero on Monday.
The low will be -1C, while it‘ll be a warmer 17C in the daytime.
Hobart will be a cool 7C overnight at the weekend, with snow on Mt Wellington possible.
Adelaide will see a low of 12C over the weekend, with Sunday reaching 19C.
Sydney will escape the cold blast, with highs of 25C expected on Saturday.
