00:00Hello it's Angus here at the Bureau and it's going to be a very windy week across Tasmania.
00:04Cold fronts will be delivering damaging wind gusts to our southern state as early as today.
00:10That's right the winds are picking up on Monday, could stay strong into Tuesday potentially even into Wednesday as well.
00:16Let's jump in and take a look, see what is going on.
00:19So on this map we've put the wind at 1.5 kilometres above sea level
00:24and the reason we look at winds at that altitude is it lets us see the overall flow of the atmosphere
00:28without having to worry about things like mountains and valleys.
00:32At the time of recording which is late Monday morning it's already getting quite windy across Tasmania
00:37but the key thing we're really looking for on this map is when those colours turn dark red and purple
00:43showing us not just the strong winds at this altitude but we know those strong winds will be reflected
00:48by damaging wind gusts down at the surface.
00:51Let's play through the remainder of Monday and watch as this front out to the west gets closer and closer
00:56and see how the wind over the state responds to that, it just gets stronger and stronger.
01:00This comes to a pause at 2am tomorrow morning so overnight tonight
01:04and that is really when the winds are expected to be the strongest
01:07is through the early hours of tonight into Tuesday morning
01:11and basically the entire state covered by those very strong winds.
01:14We also see a few stronger winds around southern Victoria
01:17although at this stage it looks like those winds in Victoria will stay below the threshold required for a warning.
01:23Let's continue to play through Tuesday, we'll actually see the wind ease off a little bit during the morning
01:28and afternoon but in the evening yet another front approaches from the west
01:32and those winds they get reinvigorated once again
01:35so it will be another very windy night from Tuesday night into Wednesday morning
01:39we continue to play through the loop now
01:41and we'll see a gradual easing on Wednesday into Thursday
01:44as the reds turn to oranges to yellows to greens
01:47telling us that those wind speeds are gradually easing across the state
01:51particularly on Thursday.
01:54So Monday to Wednesday is the key time period
01:55we have got a warning in place which covers much of the state
01:58let's zoom in for a little bit more detail
02:00and basically all of the central elevation
02:03the central plateau, the west coast
02:04that is all included in the warning area
02:06as is Hobart, the capital is included in the warning
02:10parts of the northeast and northeastern mountains as well.
02:12If you live in the yellow area here anticipate those winds to really pick up later on today
02:17this afternoon and this evening
02:19and wind gusts could approach 100km an hour
02:22probably more than that if you live at elevation
02:24the strongest winds are expected tonight and overnight
02:27tapering off a little bit through the early hours tomorrow
02:30Tuesday morning not quite as windy
02:32still a pretty windy day
02:34and then we could see those winds pick up once again
02:36on Tuesday night into Wednesday morning
02:38so it's a couple of very windy days
02:40if we do see winds of this speed 100km an hour or so
02:43that can bring down trees and branches
02:45they can fall over roads potentially closing those roads
02:48and they may damage cars and property
02:50winds of this strength can also lead to power outages
02:54the warnings in place are covering the winds
02:56but there will be some rain at the same time
02:59bands of rain really anticipated to cross Tasmania
03:02over the next few days
03:02perhaps around three different pulses of wet weather
03:05between Monday and Wednesday
03:07most of the falls will be in the mountains and on the west coast
03:10but we'll see a few showers spilling across to the north and east
03:13from time to time as well
03:15the key thing with this rain to note is that it could come
03:17embedded with some thunderstorm activity
03:20particularly on Monday afternoon and Monday evening
03:23into the night as well
03:25we may see some severe thunderstorms through central and western parts of Tasmania
03:29if we do see severe thunderstorms once again
03:31it will be because they are generating damaging wind gusts
03:35through these yellow areas
03:37so if you'd like to stay up to date with the warnings
03:39or just your local forecast and wind
03:41you can find that on the Bureau's website
