Australia came overnight as temperatures plummeted to minus 5 degrees in some parts of New York and new snowfalls were added to ski resorts.
Australia's capital cities cooled sharply in the early hours of Sunday.
Temperatures dropped to 8 degrees in Sydney, Adelaide and Hobart, 7 degrees in Melbourne and Perth, 9 degrees in Brisbane and 1 degree in Canberra, according to Weatherzone.
The piercing southeastern wind woke residents of New, Victoria and Tahrena to a chill.
Weatherzone meteorologist Jacob. Kroger (Jacobus Cronje) said temperatures in southeastern Australia fell as a result of a cold front.
"there is a cold front on the southeast coast and a low pressure system," he said.
Cold air is forming in the southeast, making it particularly cold today. While much of the new state, capital territory and eastern Victoria are still cold, temperatures are expected to rise gradually.
In western Victoria, eastern South Australia and the far west of New York, temperatures will begin to pick up, Croger said. At the same time, he predicts rain and gale weather will hit Sydney and other parts of New York's east coast in the next few days.
The cold weather is good news for those who scrub their hands for the ski season.
In the past 24 hours, snow has reached 60 centimeters in new state snow mountains and is expected to fall 10 centimeters the next day.
On Saturday night, Thredbo and Charlotte Pass had about 10 to 20 centimeters of snow, Kranger said.
On Saturday, Thredbo launched the 2018 ski season, the best day of the year, with temperatures below 5 degrees and snow of 55 centimeters, and snow is expected to continue until Tuesday.
Meteorological Bureau meteorologist Bimal KC says it could also snow in the capital territories, especially in Brindabellarange..
The KC warned that the Hunter Coast of (Hunter coast) and Illawarra Cliffs in the new state would face destructive winds of 60-70km/h, sometimes more than 90 km / h.
The wind comes from a complex depression in the Tasman Sea and directs a westerly stream over the new state, according to the Meteorological Service.
It is predicted that strong winds will continue south along the coast until tomorrow on Sunday night.
