00:00A strong cold front is crossing southeastern Australia today, with the risk of damaging winds

00:04across multiple states into tomorrow. Taking a look at our current severe weather warnings for

00:09damaging winds, we can see that they span multiple states. In South Australia, those winds are already

00:15increasing across parts of the southeast, likely to persist until later today. In Victoria, a warning

00:20covers many of our elevated parts of the state, as well as some exposed coastal areas. Most notably,

00:26large parts of the Melbourne metro area are included in this warning today and could see

00:31those damaging winds. Now, those winds are starting to ramp up this morning, but are likely to ease

00:36back through western parts of the warning area later today. We could see the risk of damaging winds

00:41persisting through the east into early tomorrow. In parts of Tasmania, the risk is expected to develop

00:48from late tonight into tomorrow across central and eastern parts of the warning area. It's worth

00:53noting that Hobart is included in that warning area. For the west coast, though, we could see

00:58some of those damaging wind gusts through this afternoon. In New South Wales, our warning covers

01:03parts of the southern tablelands, southern ranges, snowy mountains and even parts of the Australian

01:09Capital Territory. In those warning areas, winds are likely to pick up late today, going into tomorrow

01:14and continue through much of tomorrow as well, with the possibility that this warning could extend

01:19further north across the central tablelands. Now, we've already seen some strong and gusty winds

01:25developing over the past few hours, with some damaging wind gusts. Looking at some of those

01:29gusts that we've recorded since nine o'clock this morning, we can see we've already had a 93

01:34kilometer an hour wind gust at Strathalban in South Australia, 96 kilometers an hour at Kilmore Gap

01:40in Victoria. Down in Tasmania, we've seen 115 kilometers an hour at Kunanyi, Mount Wellington.

01:45So let's take a look at the weather system driving these strong winds now.

01:51It's this cold front you see here. It impacted southern parts of Western Australia yesterday

01:56and is now moving across the Bight. Ahead of this frontal system, we've got strong northerly winds,

02:02so winds coming from the north, pulling down to the southeast. They're bringing warm conditions

02:06ahead of the frontal system. We are expecting a top of 25 degrees in Adelaide today, 24 in Melbourne

02:12and 23 in Hobart, with these gusty winds continuing as the cold front approaches.

02:19Showers and thunderstorms may develop with the front, mostly with those thunderstorms along our

02:25coastal areas. The front will move through Adelaide this afternoon, likely reaching Melbourne later

02:30tonight. Most areas are going to see fairly patchy showers with rainfall totals on the low to locally

02:36moderate side of things. Our cold front will continue to sweep eastwards overnight tonight,

02:41but we have got another weather system approaching for Tasmania. That's what we call a follow-up front,

02:47another cold front that's coming through hot on the heels of our first one. That means that even as

02:52this first front moves eastwards through the course of Tuesday, windy and wet conditions are likely to

02:57persist over Tasmania a little bit longer. We are likely to see small hail and some thunderstorms

03:03continuing in the wake of our frontal system as cooler air starts to move in. It's worth noting

03:09that our maximum temperatures on Wednesday are significantly lower than what we're expecting

03:13today. For example, Hobart is only expecting 13 degrees on Wednesday, 10 degrees less than what

03:18we're forecasting today. Taking a look at our rainfall totals expected between midnight last night

03:25all the way out to six o'clock Wednesday morning. You can see that most areas are expecting generally

03:30low to moderate accumulations over the next couple of days. That's why we're seeing a lot of these

03:34blue-green colours and this pale orange here. That's indicating less than 10 or 15 millimetres or so.

03:40Some areas will see slightly more rainfall accumulating with this cold front, most notably about parts

03:46of eastern Victoria, southeast Alpine New South Wales, and through parts of western and northern Tasmania,

03:52especially as that second cold front comes through. So it's not going to be a terribly wet cold front,

03:57it's more going to be a windy one. Key weather impacts we could see with those strong to damaging winds.

04:05Damage to trees and property as those strong winds move through, particularly across our metro areas as

04:11well. That could lead to hazardous driving conditions as dangerous crosswinds develop or debris is moved over

04:16the roads. We could also see some disruptions to travel and utilities, depending on where those

04:22strong winds may produce some damage. So if you or someone you know lives across the southeast, it is

04:28essential to stay on top of those warnings as they'll tell you what to expect. You can find all the details

04:33via the Bureau's website, the BOM Weather app and via our social media. Stay safe and we'll catch you next time.
