State bracing for damaging wind blasts
Tasmanians are being warned to expect damaging winds up to 120km per hour as Australia’s southeastern states continue to feel the blast of wild winter weather.
The Bureau of Meteorology forecasts damaging winds will hit Tasmania, ranging from 60km/h in the Western Highlands on Wednesday night to peak gusts reaching 120km/h on the east coast on Thursday morning.
“Vigorous northwesterly airstream ahead of a cold front will start to develop in parts of the western half of Tasmania on Wednesday evening and move eastwards during the night,” the Bureau stated on Wednesday.
“The front will contract to the east and northeast during Thursday morning, then clear later in the afternoon.
“Winds will shift more westerly behind the front.
“Damaging winds are expected to contract to the northeast of the state during late Thursday morning, then clear later on Thursday afternoon.”
Those areas impacted include Devonport, Burnie, Launceston, St Helens, Swansea, Strahan, New Norfolk and Hobart.
Damaging wind gusts to 100km/h are possible over much of #Tasmania overnight, contracting to the east later Thursday morning. Peak gusts of around 120 km/h are possible for a period during Thursday morning about the east coast, including Swansea.https://t.co/NHL3HY0zFOpic.twitter.com/5LH2sOWQV7

Meanwhile, the rest of the country continues to brace for more cold weather as the weekend nears.
Sky News Weather meteorologist Bradlyn Oakes said there continues to be a high pressure system across most of the county, which is causing a cold front to continue to blast the southeast.
“When we have clear conditions and high pressure, a lot of the warmth at the surface escapes into the atmosphere, dropping those temperatures,” Ms Oakes said
She said the winds in Tasmania will be the “main concern” as they push the cold front towards the mainland.
“Through the evening tonight, it will push through Tasmania and into western parts of Victoria, continuing to pass eastwards throughout the day tomorrow,” Ms Oakes said.
“Then overnight Thursday night into Friday morning, we’re going to see more precipitation into NSW. That is going to see snowfall as well.”
“Through the night tonight, over 110km/h winds will be recorded in Tasmania.
“This large area of high pressure will dominate the country for the last weekend of May, with a lot of below freezing temps through the southeast on the weekend.”
The air mass will push across the Great Australian Bight on Wednesday before bringing plummeting temperatures, blustery winds, rain, snow and hail in the coming days.
The cold snap will see average daytime temperatures drop by about 4 to 6C on Friday.
The temperature will likely feel as low as 10C below average in some places as wind chill brings an icy bite.
Snow is forecast to fall in four states as early as Thursday, with a decent dump due to hit the mainland alps in NSW and Victoria.
The polar blast could even see snowfall in the northern highlands of NSW on Friday morning when the cold air surges north.
It is welcome news for skiers and snowboarders who are hoping for a strong snow base ahead of the snow season start in the second week of June.
Snow is expected to fall around 600m elevation in Tasmania, 800m in Victoria and about 1000m in southern and central NSW and the ACT.
Damaging wind gusts are due to smash coastal areas and the ranges in most of the southeastern states before the end of the week.
